We're seeing inconsistent architecture decisions, unclear ownership, and technical debt accumulating. Teams are blocked waiting for platform features. We need shared principles to enable autonomous decision-making while maintaining quality and consistency. + +**Who this is for:** +Platform Engineering team (15 engineers, 3 teams: Infrastructure, Developer Tools, Observability) + +**Last updated:** 2024-11-15 + +--- + +## North Star + +**Build infrastructure that developers trust and love to use.** + +Every platform we build should make developers more productive, not add cognitive load. Systems should be so reliable that product teams never think about them. + +--- + +## Core Values + +### 1. Simplicity Over Cleverness + +**What it means:** +We choose boring, proven technology over exciting new tools. We value systems that operators can debug at 3 AM over systems that are technically impressive. Every abstraction must pay for itself in reduced complexity. + +**Why it matters:** +Complex systems fail in complex ways. When product teams are down, they need fixes fast, not archaeology. Our 3 AM self will curse our 3 PM clever self. + +**What we optimize for:** +- Debuggability and operational simplicity +- Fewer moving parts +- Standard solutions over custom code +- Clear mental models + +**What we de-prioritize:** +- Resume-driven development +- Micro-optimizations that add complexity +- Novel approaches when proven ones exist +- Being first to adopt new tech + +**Examples:** +- Use managed PostgreSQL instead of building our own database cluster +- Choose nginx over a custom written load balancer +- Pick Kubernetes standard patterns over clever custom operators + +### 2. Reliability Over Features + +**What it means:** +Every service has SLOs and we honor them. We say no to features that compromise reliability. Reliability is a feature, not a phase. When in doubt, we prioritize preventing incidents over shipping features. + +**Why it matters:** +One platform outage affects every product team. Our unreliability multiplies across the organization. Lost trust takes months to rebuild. + +**What we optimize for:** +- SLO compliance (99.9%+ uptime for critical paths) +- Graceful degradation +- Observable systems +- Rollback capability + +**What we de-prioritize:** +- Shipping fast at the cost of stability +- Features without monitoring +- Experimentation that risks critical path +- Tight coupling that prevents safe deploys + +**Examples:** +- We run chaos engineering tests before Black Friday +- New features launch behind feature flags with gradual rollout +- We have automated rollback for all critical services + +### 3. Developer Experience is Not Optional + +**What it means:** +APIs should be intuitive, documentation should exist, and errors should be actionable. If developers are frustrated, we've failed. We design for the developer using our systems, not just for the system itself. + +**Why it matters:** +Friction in platform tools slows every product team. 100 developers × 10min friction = 1000min lost daily. Good DX multiplies productivity; bad DX multiplies frustration. + +**What we optimize for:** +- Clear, actionable error messages +- Comprehensive, up-to-date documentation +- Simple onboarding (< 1 hour to first deploy) +- Fast feedback loops + +**What we de-prioritize:** +- Internal-only jargon in APIs +- Optimization for our convenience over user experience +- Tribal knowledge over documentation +- Complex configurations + +**Examples:** +- All APIs have OpenAPI specs and interactive docs +- Error messages include links to runbooks +- We measure "time to first successful deploy" for new services + +### 4. Ownership Means Accountability + +**What it means:** +If you build it, you run it. Teams own their services end-to-end: development, deployment, monitoring, on-call. Ownership includes making your service operationally excellent, not just functionally correct. + +**Why it matters:** +Throwing code over the wall creates unmaintainable systems. Operators who didn't build it can't improve it. Builders who don't operate it don't feel the pain of poor operational characteristics. + +**What we optimize for:** +- End-to-end ownership +- Operational maturity (monitoring, alerting, runbooks) +- Empowered teams +- Learning from production + +**What we de-prioritize:** +- Separate "ops" team for platform services +- Deploying without runbooks +- Services without clear owners +- Handoffs between teams + +**Examples:** +- Infrastructure team is on-call for Kubernetes cluster +- Developer Tools team owns CI/CD pipeline end-to-end +- Each team has SLO dashboards they review weekly + +--- + +## Decision Tenets + +### When Choosing Technology + +**When evaluating new tools:** +- ✓ Choose managed services (RDS, managed K8s) over self-hosted when quality is comparable +- ✓ Pick tools with strong observability out-of-the-box +- ✓ Prefer tools our team has expertise in over "better" tools we'd need to learn +- ✗ Don't adopt because it's trending or looks good on résumé +- ⚠ **Exception:** When existing tools fundamentally can't meet requirements AND we have capacity to support + +**When building vs buying:** +- ✓ Build when our requirements are unique or when vendors don't exist +- ✓ Buy when it's undifferentiated heavy lifting (observability, databases) +- ✗ Don't build for the joy of building +- ⚠ **Exception:** Build when vendor lock-in risk outweighs development cost + +### When Making Architecture Decisions + +**When designing APIs:** +- ✓ Choose RESTful JSON APIs as default (boring, widely understood) +- ✓ Design for the developer experience, document before implementing +- ✗ Don't create bespoke protocols without strong justification +- ⚠ **Exception:** gRPC for high-performance internal services + +**When choosing between perfection and shipping:** +- ✓ Ship with known minor issues if they don't affect SLOs +- ✓ Document technical debt and schedule fixes +- ✗ Don't ship if it compromises security, data integrity, or violates SLOs +- ⚠ **Exception:** Never compromise on security, payments, or PII handling + +### When Prioritizing Work + +**When product teams request features:** +- 🔴 **Critical:** SLO violations, security issues, data loss risks +- 🟡 **Important:** Developer friction affecting >3 teams, technical debt preventing new features +- ⚪ **Nice-to-have:** Single-team requests, optimizations, new nice-to-have features + +**When allocating time:** +- 70% Product work (features product teams need) +- 20% Platform health (tech debt, improvements) +- 10% Innovation (experiments, R&D) + +--- + +## Observable Behaviors + +### In Code Reviews + +- We comment on operational characteristics (What happens when this fails?

Can't fix what we can't observe. + +✗ **Optimize prematurely** - even when we see potential improvements + - **Because:** Simplicity > Performance. Measure first, optimize if needed. + +✗ **Build custom solutions for solved problems** - even when it seems fun + - **Because:** Maintenance cost exceeds initial development 10x.

Our job is to say no to bad ideas. + +✗ **Deploy Friday afternoon** - even when it seems low-risk + - **Because:** Reliability matters more than shipping fast. Weekend incidents aren't worth it. + +--- + +## How to Use This + +### In Decision-Making + +**When stuck between two options:** +1. Check decision tenets above +2. Ask "Which choice better serves our North Star?" +3. Consider which value is most relevant +4. Document decision in ADR with rationale + +### In Hiring + +**Interview questions tied to values:** +- **Simplicity:** "Tell me about a time you refactored complex code to be simpler. What drove that decision?" +- **Reliability:** "How do you decide when to ship vs. when to delay for quality?" +- **Developer Experience:** "What makes a good API? Show me an API you love and why." +- **Ownership:** "How do you approach on-call? What makes a service operationally mature?" + +### In Onboarding + +**Week 1:** New engineers read this document and discuss in 1:1 +**Week 2:** Shadow on-call to see ownership in practice +**Week 3:** Pair on feature to see values in code review +**Month 1:** Present one architectural decision using these tenets + +### In Performance Reviews + +We evaluate on: +- **Simplicity:** Do they choose boring solutions? Do they reduce complexity? +- **Reliability:** Do their services meet SLOs? How do they handle incidents? +- **Developer Experience:** Is their code/APIs/docs easy to use? +- **Ownership:** Do they own services end-to-end? Do they improve operations? + +### When Values Conflict + +**Simplicity vs Developer Experience:** +- **Winner:** Developer Experience.

Self-hosted gives more control and learning opportunity. + +**Decision:** Chose AWS RDS PostgreSQL (managed service). + +**Values applied:** +- ✓ Simplicity > Cleverness: Less operational burden +- ✓ Ownership: Team doesn't have DB expertise yet +- ✓ Reliability: AWS has better uptime than we'd achieve + +**Outcome:** Service launched in 2 weeks vs. estimated 6 weeks for self-hosted setup and learning. Zero database incidents in 6 months. + +### Example 2: Said No to Real-Time Features + +**Situation:** Product team requested real-time notifications (WebSockets) for dashboard. + +**Decision:** Said no, proposed 30-second polling instead. + +**Values applied:** +- ✓ Simplicity: Polling is simpler than WebSocket infrastructure +- ✓ Reliability: Don't risk stability for nice-to-have feature +- ✓ Developer Experience: Team lacks WebSocket experience + +**Outcome:** Shipped in 1 week with polling. User research showed 30s delay was acceptable.

Example: "Product feature will achieve >20% adoption within 3 months" - matters for launch decision. + +**Step 2: Establish prior beliefs** + +Set initial probability using base rates (general frequency), reference class (similar situations), specific differences, and explicit probability assignment with justification. Good priors are based on base rates, account for differences, honest about uncertainty, and include ranges if unsure (e.g., 40-60%). Avoid purely intuitive priors, ignoring base rates, or extreme values without justification. + +**Step 3: Identify evidence and likelihoods** + +Assess evidence (specific observation/data), diagnostic power (does it distinguish hypotheses?), P(E|H) (probability if hypothesis TRUE), P(E|¬H) (probability if FALSE), and calculate likelihood ratio = P(E|H) / P(E|¬H). LR > 10 = very strong evidence, 3-10 = moderate, 1-3 = weak, ≈1 = not diagnostic, <1 = evidence against. + +**Step 4: Calculate posterior** + +Apply Bayes' Theorem: P(H|E) = [P(E|H) × P(H)] / P(E), or use odds form: Posterior Odds = Prior Odds × Likelihood Ratio. Calculate P(E) = P(E|H)×P(H) + P(E|¬H)×P(¬H), get posterior probability, and interpret change. For simple cases → Use `resources/template.md` calculator. For complex cases (multiple hypotheses) → Study `resources/methodology.md`. + +**Step 5: Calibrate and document** + +Check calibration (over/underconfident?), validate assumptions (are likelihoods reasonable?), perform sensitivity analysis, create `bayesian-reasoning-calibration.md`, and note limitations. Self-check using `resources/evaluators/rubric_bayesian_reasoning_calibration.json`: verify prior based on base rates, likelihoods justified, evidence diagnostic (LR ≠ 1), calculation correct, posterior calibrated, assumptions stated, sensitivity noted.

Suspend criticism (all ideas valid during divergence), aim for quantity and variety (different types, scales, approaches), and use creative prompts: "What if unlimited resources?", "What would competitor do?", "Simplest approach?", "Most ambitious?", "Unconventional alternatives?". Output: Numbered list of raw ideas. For simple topics → generate directly. For complex topics → Use `resources/template.md` for structured prompts. + +**Step 3: Cluster (group themes)** + +Organize ideas into 4-8 distinct clusters by identifying patterns, creating categories (mechanism, user/audience, timeline, effort, risk, strategic objective), naming clusters clearly, and checking coverage (distinct approaches). Fewer than 4 = not enough variety, more than 8 = too fragmented. Output: Ideas grouped under cluster labels. + +**Step 4: Converge (evaluate and select)** + +Define criteria (from step 1), score ideas on criteria (1-10 or Low/Med/High scale), rank by total/weighted score, select top 3-5 options, and document tradeoffs (why chosen, what deprioritized). Evaluation patterns: Impact/Effort matrix, weighted scoring, must-have filtering, pairwise comparison. See [Common Patterns](#common-patterns) for domain-specific approaches. + +**Step 5: Document and validate** + +Create `brainstorm-diverge-converge.md` with: problem statement, diverge (full list), cluster (organized themes), converge (scored/ranked/selected), and next steps. Validate using `resources/evaluators/rubric_brainstorm_diverge_converge.json`: verify 20+ ideas with variety, distinct clusters, explicit criteria, consistent scoring, top selections clearly better, actionable next steps.

Weighted Synthesis** +- "We'll prioritize X, while incorporating safeguards for Y's concerns" +- Example: "Ship fast (PM's priority), but with feature flags and monitoring (Engineer's concern)" + +**2. Sequencing** +- "First we do X, then we address Y" +- Example: "Launch MVP to test market (Growth), then invest in quality (Engineering) once product-market fit is proven" + +**3.

Debate + +### Key Points of Disagreement + +**Dimension 1: Timeline - Fast (Buy) vs. Perfect (Build)** +- **VP Sales**: Need it in 3 months to support Q4. Cannot wait 12+ months for custom build. +- **Engineering Lead**: 6-month build timeline is achievable with focused team. SaaS implementation still takes 2-3 months (not that much faster). +- **Finance**: Every month of delay costs $3K in lost productivity. Time is money. +- **Tension**: Speed to value vs. building it right + +**Dimension 2: Fit - Good Enough (Buy) vs. Perfect (Build)** +- **VP Sales**: 80% fit is fine if it's reliable and fast. Sales reps can adapt process slightly. +- **Engineering Lead**: 80% fit means 20% pain forever. Our 2-stage approval is core to how we sell. +- **Finance**: "Perfect fit" is theoretical. Custom builds often ship with missing features or bugs. +- **Tension**: Process flexibility vs. tool flexibility + +**Dimension 3: Cost - Predictable (Buy) vs. Upfront (Build)** +- **VP Sales**: $50K/year is predictable, budgetable, and includes support/updates. +- **Engineering Lead**: $50K/year = $250K over 5 years. Build is $300K once, then $30K/year = $420K over 5 years. But we own it. +- **Finance**: Engineering track record suggests $300K becomes $400K. Risk-adjusted, not clear build is cheaper. +- **Tension**: Upfront vs. ongoing, certain vs. uncertain + +**Dimension 4: Risk - Operational (Buy) vs. Execution (Build)** +- **VP Sales**: Execution risk is high (engineering track record). Operational risk with SaaS is low (proven, 99.9% uptime). +- **Engineering Lead**: Vendor risk is real (lock-in, pricing changes, product direction). We control our own destiny with custom build. +- **Finance**: Both have risks. Mitigatable? SaaS = switching costs. Build = timeline/budget overruns. +- **Tension**: Vendor dependency vs. execution capability + +### Debate Transcript (Point-Counterpoint) + +**VP Sales Opening Case:** + +Look, I get the appeal of building our perfect CRM, but we cannot afford to wait 12-18 months. Our sales team is losing deals *right now* because we don't have proper pipeline tracking. I had a rep miss a $50K deal last month because a follow-up fell through the cracks in our spreadsheet system. + +The reality is that engineering has a track record of delays. The deal calculator took 14 months instead of 8. The reporting dashboard was 6 months late. If we start a custom build today, best case is 12 months to launch, realistically 18 months. By then, we'll have lost $100K+ in productivity and missed deals. + +A SaaS solution like HubSpot can be operational in 2-3 months. Yes, it's not a perfect fit for our 2-stage approval, but we can adapt our process slightly or use workflow automation. The key is: it works, it's reliable, and my sales team will actually use it because it's polished and familiar. + +The $50K/year cost is worth it for the speed, reliability, and ongoing support. We get updates, new features, and 24/7 support included. If we build custom and it breaks during Q4, who fixes it? Engineering is focused on product features, not internal tools. + +**Engineering Lead Response:** + +I appreciate the urgency, but "speed at any cost" is how we end up with tools that don't fit our needs and frustrate users. Let me address the timeline concern: I'm proposing a 6-month build, not 12-18 months. We scope it tightly to core CRM features (contacts, deals, pipeline, basic reporting). No gold-plating. + +Yes, past projects have run over, but those were exploratory with unclear requirements. This is a well-defined problem. We've built CRMs before (I personally built one at my previous company in 5 months). With 2 senior engineers dedicated full-time, 6 months is realistic. + +On the "good enough" point: Our 2-stage approval process is non-negotiable. It's a compliance requirement and competitive differentiator. SaaS CRMs make this painful or impossible. I've demoed HubSpot - their approval workflows are clunky and don't match our needs. Sales reps will work around the system, undermining data quality. + +On cost: Yes, $50K/year seems manageable, but that's $250K over 5 years, $500K over 10 years, *forever*. And that's today's price. SaaS pricing increases 5-10% per year. We're also locked in - switching CRMs later is a $100K+ migration project. Build once, own forever, total control. + +And let's not forget: We can build exactly what we need. Want a custom integration with our accounting system? Done. Want automated deal scoring based on our proprietary criteria? Done. SaaS tools require expensive consultants or hacky API integrations that break on upgrades. + +**VP Sales Rebuttal:** + +Six months is your *best case* estimate. But you're assuming everything goes perfectly: no scope creep, no technical challenges, no distractions from product team priorities. Even if you hit 8 months, that's 5 months longer than SaaS, costing us $15K+ in lost productivity. + +On the 2-stage approval: I've seen it work in HubSpot via custom workflows and approval automations. It's not perfect, but it's workable. And honestly, maybe our process could use some optimization. SaaS CRMs embody industry best practices - might be an opportunity to streamline. + +On the "locked in" concern: Sure, switching CRMs is painful. But building custom and then replacing it later is *also* painful (arguably more so - you're throwing away $300K of investment). At least with SaaS, you can evaluate competitors and switch if needed. With custom, you're locked into your own technical debt. + +Here's my core concern: *Adoption risk*. Sales reps have used Salesforce or HubSpot before. They know the interface, the mobile app, the workflows. Your custom CRM, no matter how well-built, will feel unfamiliar. Adoption could be slow or fail entirely. Then we've spent $300K on a tool no one uses. + +**Engineering Lead Rebuttal:** + +On timeline: I hear your skepticism given our track record. What if we mitigate that risk? We could do a phased approach: MVP in 3 months (just contact management and deal tracking), then add features incrementally. If the MVP works, we continue. If not, we bail after $75K and switch to SaaS. That's a middle ground. + +On adoption: Fair point. But I'd argue familiarity cuts both ways. Sales reps are frustrated with *current* tools that don't fit our process. A custom tool that matches their workflow could actually drive *better* adoption than a foreign SaaS tool they need to work around. We'd design with sales team input from day one. + +On process optimization: I'm not opposed to improving the process, but the 2-stage approval isn't arbitrary - it's a compliance requirement from our legal team. We can't just "streamline" it away. A SaaS tool that doesn't support it is a non-starter, full stop. + +On the cost trajectory: You're right that switching from custom later is painful. But switching from SaaS is *also* painful, *plus* we've paid $250K in subscription fees *plus* we've built dependencies on their platform. At least with custom, we own the asset. + +**Finance Cross-Examination:** + +**Finance to Engineering**: "You say 6 months and $300K. Our historical data shows engineering projects run +40% over budget. Shouldn't we plan for 8-9 months and $400K as the realistic case?" + +**Engineering**: "Fair. If we scope tightly and use my phased approach (MVP first), I'm confident in 6 months. But yes, let's budget $350K to be safe." + +**Finance to VP Sales**: "You say SaaS is $50K/year. Have you confirmed that price includes 30 users, all features we need, and API access for integrations?" + +**VP Sales**: "I've gotten quotes. HubSpot Professional is $45K/year for 30 users. Salesforce is $55K/year. Both include core features. API access is included, though there are rate limits." + +**Finance to both**: "Here's the cost comparison I'm seeing: +- **SaaS (HubSpot)**: $20K implementation + $50K/year × 3 years = $170K (3-year TCO) +- **Build**: $350K (risk-adjusted) + $30K/year × 3 years = $440K (3-year TCO) + +SaaS is $270K cheaper over 3 years. Engineering, what would need to be true for build to be cheaper?" + +**Engineering**: "Two things: (1) We'd need to run the custom CRM for 7+ years for TCO to break even. (2) If SaaS costs increase to $70K/year (SaaS companies often raise prices), break-even is 5 years. I'm thinking long-term; you're thinking 3-year horizon." + +**VP Sales to Engineering**: "What happens if you start the build and realize at month 4 that you're behind schedule or over budget? Do we have an exit ramp, or are we committed?" + +**Engineering**: "That's why I proposed phased approach with MVP milestone. At 3 months, we review: Is MVP working? Is it on budget? If yes, continue. If no, we pivot to SaaS. That gives us an exit ramp." + +### Cruxes (What Would Change Minds) + +**VP Sales would shift to Build if:** +- Engineering commits to 6-month delivery with phased milestones and exit ramps +- MVP is demonstrated at 3 months with core functionality working +- Sales reps are involved in design from day one (adoption risk mitigation) +- There's a backup plan (SaaS) if custom build fails + +**Engineering Lead would shift to Buy if:** +- SaaS demo shows it can handle 2-stage approval workflow without painful workarounds +- Cost analysis includes long-term subscription growth (10-year TCO, not 3-year) +- We retain option to migrate to custom later if SaaS limitations become painful +- Data export and portability are guaranteed (no vendor lock-in on data) + +**Finance would support Build if:** +- Timeline is credibly 6 months with phased milestones (not 12-18 months) +- Budget is capped at $350K with clear scope controls +- Adoption plan is strong (sales team involvement, training, change management) +- Long-term TCO analysis shows break-even within 5-7 years + +**Finance would support Buy if:** +- 3-year TCO is significantly lower ($170K vs $440K) +- Predictable costs with no surprises +- Adoption risk is low (familiar interface for sales reps) +- Operational in 2-3 months to start capturing productivity gains + +### Areas of Agreement + +Despite disagreements, all three roles agree on: +- **Current state is unacceptable**: Spreadsheets are costing us deals and productivity +- **Timeline pressure**: Need solution operational before end of year +- **Adoption is critical**: Doesn't matter if we build or buy if sales team doesn't use it +- **2-stage approval is non-negotiable**: Compliance requirement can't be compromised +- **Budget constraint**: ~$150K available this year, need to stay within bounds + +--- + +## 4.

If MVP fails, we pivot to SaaS and only lost 3 months. + +- **Risk of $100K sunk cost if MVP fails** + - **Rationale**: $100K is our "learning cost" to validate whether custom build can work. Still cheaper than committing to $250K+ full build that might fail. + +**We're NOT accepting:** +- **Blind commitment to custom build** (Engineering's original proposal) + - **Reason**: Too risky given track record. MVP + gate reduces risk. + +- **Immediate SaaS adoption** (Sales' original proposal) + - **Reason**: Doesn't test whether custom fit is achievable. Worth 3 months to find out. + +- **Waiting 12+ months for full custom solution** (original concern) + - **Reason**: Phased approach with exit ramps means we pivot to SaaS if build isn't working by month 3. + +### Addressing Each Role's Core Concerns + +**VP Sales's main concern (speed and adoption) is addressed by:** +- MVP in 3 months (not 12-18 months) +- Exit ramp at month 3 if build is behind schedule +- Sales team involved in MVP design (adoption risk mitigation) +- Fallback to SaaS if build doesn't work out + +**Engineering Lead's main concern (custom fit and control) is addressed by:** +- Opportunity to prove custom build is feasible via MVP +- If MVP succeeds, we complete the build (Phases 3) +- 2-stage approval built exactly as needed +- Only pivot to SaaS if custom build *demonstrably* fails (data-driven decision) + +**Finance's main concern (cost and risk) is addressed by:** +- Capital-efficient: Only $100K at risk before decision gate +- Clear decision criteria at month 3 (on budget? on schedule? working?) +- Capped budget: $250K total if we complete build (vs. $350K uncapped original proposal) +- Predictable costs: SaaS fallback available if build overruns + +--- + +## 5. Recommendation + +**Recommended Action:** +Pursue phased build with MVP milestone at 3 months and decision gate (continue build vs. pivot to SaaS). + +**Rationale:** + +This synthesis is superior to either "pure build" or "pure buy" because it: + +1. **Tests feasibility before full commitment**: The MVP validates whether we can build the custom CRM on time and on budget. If yes, we continue. If no, we pivot to SaaS with only $100K sunk cost. + +2. **Mitigates execution risk (Sales' top concern)**: Exit ramp at month 3 means we're not locked into a long, uncertain build. If engineering can't deliver, we bail quickly and go SaaS. + +3. **Preserves custom fit option (Engineering's top concern)**: If MVP succeeds, we get the perfectly tailored CRM with 2-stage approval. If SaaS doesn't fit our needs (as Engineering argues), we've built the right solution. + +4. **Optimizes cost under uncertainty (Finance's top concern)**: We only invest $100K to learn whether custom build is viable. If it works, total cost is $250K (less than original $350K). If it doesn't, we pivot to SaaS having "paid" $100K for the knowledge that custom wasn't feasible. + +The key insight from the debate: **The real uncertainty is execution capability, not which option is better in theory**. By building an MVP first, we resolve that uncertainty before committing the full budget. + +**Key factors driving this decision:** +1. **Execution risk** (from Sales): Phased approach with exit ramps mitigates this +2. **Custom fit value** (from Engineering): MVP tests whether we can actually build it +3. **Cost efficiency** (from Finance): Capital-efficient with decision gate before full investment + +--- + +## 6.

What am I doing wrong?" + +**Chef Assistant response**: +1. **Diagnosis**: Likely overcooked. Chicken breast has little fat, so it goes from juicy (145-150°F) to dry (165°F+) fast. +2. **Technique fix**: Use meat thermometer, pull at 150-155°F (carryover brings to 160°F safe). +3. **Flavor fix**: Dry brine (1% salt by weight, 6-24h) keeps it juicy. +4. **Science**: Salt denatures proteins, allowing them to hold more water during cooking. +5. **Texture add**: Finish with crispy skin or crunchy topping for contrast. +6. **Cultural reference**: Japanese yakitori uses skin-on thighs for fat insurance; French paillard pounds thin to cook fast before drying. + +**Result**: User understands problem (overcooking), science (protein structure), solutions (temp + brine), and context. + +## Workflow + +Copy this checklist and track your progress: + +``` +Chef Assistant Progress: +- [ ] Step 1: Define cooking goal and constraints +- [ ] Step 2: Identify key techniques and principles +- [ ] Step 3: Build flavor architecture +- [ ] Step 4: Plan texture and contrast +- [ ] Step 5: Execute with sensory cues and precision +- [ ] Step 6: Plate and present with intention +``` + +**Step 1: Define cooking goal** + +Specify what you're making, dietary constraints, equipment available, skill level, and time budget.

Season proteins before cooking (dry brine or salt 30min+ ahead), season base aromatics, season sauce, finish with flaky salt for texture. + +2. **Use meat thermometer**: Visual cues alone are unreliable. Invest in instant-read thermometer. Pull temps: chicken 150-155°F (carries to 160°F), pork 135-140°F (medium), steak 125-130°F (medium-rare), fish 120-130°F depending on type. + +3. **Taste as you go**: Adjust seasoning incrementally. Add salt/acid/fat in small amounts, taste, repeat. Can't un-salt, but can always add more. + +4. **Mise en place before heat**: Prep everything before you start cooking. Dice all vegetables, measure spices, prep aromatics. High-heat cooking moves fast—no time to chop mid-sear. + +5. **Control heat**: Most home cooks cook too hot. High heat for searing only. Medium for sautéing aromatics. Low for sauces and gentle cooking. Preheat pans properly (water droplet test). + +6. **Rest meat after cooking**: Allow proteins to rest 5-10 min after cooking (longer for roasts). Juices redistribute, carryover cooking completes. Tent with foil if worried about cooling. + +7. **Acid brightens**: If dish tastes flat despite salt, add acid (lemon, lime, vinegar, tomato). Acid wakes up flavors and balances richness. + +8. **Fat carries flavor**: Aroma compounds are fat-soluble. Toast spices in oil/butter to release flavor. Finish sauces with fat for body and sheen. + +**Common pitfalls:** + +- ❌ **Overcrowding pan**: Creates steam, not sear. Leave space between items. Cook in batches if needed. +- ❌ **Moving food too much**: Let it sit to develop crust. Don't flip steak 10 times—flip once. +- ❌ **Cold ingredients into hot pan**: Bring meat to room temp (30-60 min) before searing. Cold center = overcooked outside. +- ❌ **Using dull knives**: Dull knives slip and are dangerous. Sharp knives cut cleanly with control. Hone regularly, sharpen periodically. +- ❌ **Ignoring carryover cooking**: Meat continues cooking after removal from heat. Pull 5-10°F below target temp. +- ❌ **Undersalting**: Most home cooking is undersalted.

Food Science Fundamentals + +### Heat Transfer Methods + +**Conduction** (direct contact): Heat through molecular contact. Examples: Pan searing, grilling. Control: Surface temp (400-450°F for Maillard, 500°F+ for pizza). Preheat thoroughly, don't move food. + +**Convection** (fluid movement): Hot air/liquid circulates. Examples: Roasting, frying, boiling. Control: Oven/liquid temp, air circulation. Space items for airflow. + +**Radiation** (infrared): Energy as electromagnetic waves. Examples: Broiling, grilling over coals. Control: Distance from heat. Broil close for crust, far for gentle cooking. + +### Maillard Reaction + +**What**: Chemical reaction between amino acids and reducing sugars creating flavor compounds. + +**Requirements**: Temp 300-500°F (accelerates 310°F+), dry surface (moisture inhibits), slightly alkaline pH helps, time for complexity. + +**Applications**: Searing meat, roasting vegetables, toasting nuts/spices/bread, browning fond for sauces. + +**Optimization**: Dry brine proteins (draws moisture, concentrates surface proteins), high smoke-point fat (avocado, grapeseed, clarified butter), don't crowd pan (steam inhibits), let crust form before flipping. + +### Protein Denaturation + +**Process**: Heat causes proteins to unfold and bond, changing texture. + +**Temperature stages**: 120-130°F myosin denatures (rare steak), 140-150°F collagen shrinks squeezing water (drier), 160°F+ actin denatures (well-done, dry), 180°F+ collagen converts to gelatin (braising temp for tough cuts). + +**Implications**: Tender cuts cook to 125-145°F, tough cuts with collagen cook to 180°F+ (collagen → gelatin), fish 120-140°F (delicate), eggs 145°F whites set, 155°F yolks set, 180°F rubbery. + +**Techniques**: Brining (salt denatures proteins, allows water retention), marinades (acid denatures surface, can make mushy if too long), resting (proteins relax and reabsorb liquid). + +### Emulsions + +**Definition**: Suspension of one liquid in another (fat in water or vice versa). + +**Types**: Oil-in-water (vinaigrette, mayo, hollandaise), water-in-oil (butter). + +**Emulsifiers**: Lecithin (egg yolks, mustard), proteins (milk, egg whites), gums/starches. + +**Technique**: (1) Start with emulsifier, (2) add oil dropwise at first, (3) whisk vigorously, (4) can add faster once emulsion forms, (5) if breaks: start with fresh emulsifier, slowly whisk in broken emulsion. + +**Applications**: Vinaigrette (mustard emulsifier), mayonnaise (egg yolk), hollandaise (egg yolk + butter warm), pan sauce (butter emulsified into reduced liquid—monte au beurre), beurre blanc (butter into wine-vinegar reduction). + +### Starch Gelatinization + +**Process**: Starch granules absorb water and swell, thickening liquids. + +**Temp ranges**: 140-150°F granules begin swelling, 180-212°F full gelatinization (max thickness), 212°F+ boiling (granules rupture if over-stirred, losing thickness). + +**Applications**: Roux-based sauces (béchamel, velouté, gravy), corn starch slurries (stir-fries, pie fillings), rice/pasta cooking (starch releases into water, creates sauce body). + +**Technique**: Cold start for roux (cook flour in fat before liquid to avoid lumps), slurry for corn starch (mix with cold water before adding to hot), pasta water for sauce (starchy water emulsifies, helps cling). + +--- + +## 2. Mother Sauces & Derivatives + +### Five Mother Sauces + +**1. Béchamel** (white): Milk + white roux. Ratio: 2 Tbsp roux per cup milk. Derivatives: Mornay (+ cheese), soubise (+ onions). + +**2. Velouté** (blond): Light stock (chicken/fish/veal) + blond roux. Ratio: 2 Tbsp roux per cup stock. Derivatives: Allemande (+ egg yolk + lemon), suprême (+ cream). + +**3. Espagnole** (brown): Brown stock + brown roux + tomato paste + mirepoix. Ratio: 3 Tbsp roux per cup stock. Derivatives: Demi-glace (+ reduced stock), bordelaise (+ red wine + shallots). + +**4. Tomato**: Tomatoes + aromatics + stock. Slow simmer to concentrate. Derivatives: Marinara (garlic + herbs), arrabbiata (+ chili). + +**5. Hollandaise** (emulsified butter): Egg yolks + melted butter + lemon. Gentle heat (double boiler), slow butter addition. Derivatives: Béarnaise (+ tarragon + shallots), maltaise (+ orange). + +### Modern Pan Sauce Formula + +**Template**: (1) Fond (brown bits after searing), (2) aromatics (shallots/garlic/thyme 30 sec), (3) deglaze (¼-½ cup wine/stock/juice, scrape fond, reduce by half), (4) enrich (swirl 1-2 Tbsp cold butter—monte au beurre), (5) finish (lemon juice + herbs + salt). + +**Variations**: Red wine sauce (red wine + beef stock + thyme), white wine sauce (white wine + chicken stock + tarragon), citrus sauce (OJ + stock + ginger), cream sauce (wine + stock → reduce → cream → reduce again). + +--- + +## 3. Flavor Pairing Systems + +### The Flavor Mixing Board (10 Elements) + +**1. Salt**: Enhances all flavors, reduces bitterness. Types: Kosher (cooking), flaky (finishing), sea (complex). Dosage: 1-2% by weight. Timing: Multiple stages (proteins early, sauces throughout, finish at end). + +**2. Acid**: Brightens flavors, cuts richness, balances sweet. Types: Citrus (bright, aromatic), vinegar (clean, sharp), wine (complex), tomato (savory-acid). Dosage: Start ½ tsp, build. Timing: Add at end (heat dulls) or simmer to mellow. + +**3. Fat**: Carries aroma, creates body, balances acid/heat. Types: Butter (rich, milk solids), olive oil (fruity), cream (smooth), nuts (texture + fat). Timing: Toast spices in fat early, finish sauces with fat for sheen. + +**4. Heat/Spice**: Excitement, complexity. Types: Black pepper (sharp), chili (capsaicin), ginger (warm), wasabi (nasal). Dosage: Build slowly, can't remove. Timing: Toast early for depth, add raw for brightness. + +**5. Sweet**: Balances acid/bitter/spice, caramelization. Types: Sugar (clean), honey (floral), fruit (complex), mirin (savory-sweet). Dosage: Subtle in savory. Timing: Early for Maillard, late for balance. + +**6. Bitter**: Complexity, palate cleansing. Types: Charred vegetables, dark greens, coffee, dark chocolate. Dosage: Use restraint. Timing: Controlled charring, blanch to reduce bitterness. + +**7. Umami**: Savory depth, "fifth taste." Types: Glutamates (parmesan, tomato, soy), nucleotides (mushrooms, seafood, aged meats). Dosage: Layer multiple sources. Timing: Build throughout cooking. + +**8. Aroma**: 80% of flavor. Types: Herbs (fresh/dried), alliums (garlic/onion), citrus zest, spices. Dosage: Dried herbs early, fresh late. Timing: Fat-soluble (cook in oil), volatile (finish fresh). + +**9. Water/Liquid**: Carrier, dissolves, dilutes, creates texture. Types: Stock (umami), wine (acid + complexity), coconut milk (fat + sweet). Timing: Reduce to concentrate, add to thin. + +**10. Texture**: Mouthfeel, satisfaction. Types: Crispy, creamy, chewy, tender, crunchy, smooth. Dosage: At least one contrast per dish. Timing: Crispy elements added last (stay crisp). + +### Flavor Pairing Strategies + +**Complementary**: Ingredients share aroma compounds. Examples: Strawberry + basil (methyl cinnamate), chocolate + coffee (pyrazines), lamb + rosemary (terpenes). + +**Contrasting**: Opposing flavors create balance. Examples: Sweet + salty (salted caramel), rich + acid (fatty fish + lemon), spicy + sweet (Thai chili-lime-sugar). + +**Bridge ingredients**: Connect disparate flavors. Examples: Balsamic bridges strawberries and black pepper, miso bridges chocolate and berries, orange bridges beets and goat cheese. + +--- + +## 4. Advanced Cooking Techniques + +### Dry-Brining + +**Principle**: Salt draws moisture out via osmosis, then protein reabsorbs with salt dissolved, seasoning deeply. + +**Benefits**: Even seasoning throughout, moisture retention during cooking, crispy skin (dry surface). + +**Method**: (1) Calculate 0.8-1.2% salt by weight (weigh protein × 0.01), (2) rub salt evenly, (3) place uncovered on rack in fridge, (4) wait (fish 30-90min, chicken/steak 6-24h, roasts 24-48h), (5) pat dry, cook (no additional salt). + +**Science**: Salt denatures surface proteins, breaking structure to hold more water. + +### Sous Vide + +**Principle**: Cook in vacuum-sealed bag in water bath at precise temp for even, edge-to-edge doneness. + +**Benefits**: Perfect doneness throughout, impossible to overcook (at target temp), tenderization over long times (tough cuts at 140-165°F for 24-72h). + +**Method**: (1) Season, seal in bag, (2) set water bath to target final temp (130°F for medium-rare), (3) cook (steaks 1-4h, chicken 1-3h, short ribs 48-72h), (4) sear after for crust (30 sec/side, screaming hot pan). + +**Limitations**: No Maillard crust (must sear after), requires equipment. + +### Confit + +**Principle**: Cook and preserve in fat at low temp (180-200°F) until tender, store in fat. + +**Traditional**: Duck confit (legs in duck fat 2-3h). **Modern**: Olive oil confit (garlic, tomatoes, fish at 180°F until tender). + +**Method**: (1) Season (salt, herbs), (2) submerge in fat, (3) cook low (180-200°F) until tender (1-3h duck, 30-60min fish/garlic), (4) cool in fat, store submerged (weeks in fridge), (5) reheat by crisping in oven. + +**Science**: Low temp tenderizes without drying, fat seals from oxygen (preservation). + +### Braising + +**Principle**: Sear for crust, then slow-cook partially submerged in liquid until collagen converts to gelatin. + +**Ideal for**: Tough cuts with collagen (short ribs, shanks, brisket, pork shoulder). + +**Method**: (1) Sear all sides (Maillard, fond), (2) sauté mirepoix, (3) deglaze with wine (scrape fond), (4) add stock (halfway up protein), herbs, cover, 275-325°F oven, (5) cook 2-4h until fork-tender (collagen → gelatin at 180°F+), (6) remove protein, reduce liquid to sauce. + +**Science**: Collagen breaks into gelatin at 180°F+, requires time. Sauce is rich and glossy. + +### Fermentation + +**Principle**: Microbes transform ingredients, creating complex flavors (umami, acid, funk). + +**Common applications**: Lacto-fermentation (vegetables + salt → lactic acid, sauerkraut/kimchi), koji fermentation (rice + *Aspergillus oryzae* → miso/soy sauce), wild fermentation (sourdough). + +**Quick ferment** (3-7 days): (1) Submerge vegetables in 2-3% salt brine (20-30g per liter water), (2) keep submerged (weight down), (3) room temp loosely covered, (4) taste daily (tangier over time), (5) refrigerate when desired. + +**Benefits**: Umami, probiotic, shelf-stable, complex acid. + +--- + +## 5. Cultural Cooking Methods + +### French Classical + +**Philosophy**: Precision, technique mastery, sauce-centric, refinement. + +**Core techniques**: Mother sauces, mise en place rigor, knife skills (brunoise, julienne, chiffonade), stock-making (fond de cuisine). + +**Flavor approach**: Layered, technique-driven, butter and cream for richness, wine for acidity, fine herbs (tarragon, chervil, parsley). + +**Example**: Coq au vin (braise chicken in red wine, lardons, pearl onions, mushrooms). + +### Italian Rustic + +**Philosophy**: Simple ingredients, quality-driven, seasonal, carb-centric (pasta, bread, polenta). + +**Core techniques**: Pasta making and saucing (emulsify with pasta water), risotto (slow stock addition, constant stirring), braising (osso buco, ragu). + +**Flavor approach**: Minimal ingredients, let quality shine, acid from tomato/wine, olive oil foundation, parmigiano for umami, fresh basil/oregano. + +**Example**: Cacio e pepe (pasta, pecorino, black pepper, pasta water—emulsification). + +### Japanese Washoku + +**Philosophy**: Balance, seasonality, umami layering, presentation as art. + +**Core techniques**: Dashi (kombu + katsuobushi stock—umami base), delicate knife work (sashimi, vegetables), grilling (yakitori, robata), pickling (tsukemono). + +**Flavor approach**: Umami-forward (dashi, miso, soy), subtle seasoning, balance five colors/five tastes, mirin for sweet-savory. + +**Example**: Miso soup (dashi base + miso + tofu + wakame—umami layered, miso added at end to preserve probiotics). + +### Thai Balance + +**Philosophy**: Every dish balances four flavors (sweet/sour/salty/spicy), bright and aromatic, fresh herbs. + +**Core techniques**: Pounding curry pastes (mortar and pestle), stir-frying (high heat, fast), balancing nam prik (chili sauces). + +**Flavor approach**: Fish sauce (salty-umami), lime (sour), palm sugar (sweet), chili (spicy). Fresh herbs at end (Thai basil, cilantro, mint). Coconut milk for richness. + +**Example**: Tom yum (hot and sour soup—lemongrass, galangal, lime, chili, fish sauce, shrimp). + +### Mexican Layered Heat + +**Philosophy**: Chili-centric, complex heat (not just spicy), corn and beans foundation, bright acid. + +**Core techniques**: Toasting dried chilies (depth before rehydrating), masa preparation (nixtamalization—corn + lime), slow-cooked salsas (charred tomatillos, chilies). + +**Flavor approach**: Layer chili varieties (ancho=sweet, chipotle=smoky, habanero=bright heat), lime for acid, cilantro for aroma, cumin for earthy depth. + +**Example**: Mole (complex sauce—20+ ingredients, chilies, chocolate, spices, hours of toasting and blending). + +--- + +## 6. Advanced Troubleshooting + +### When Salt Doesn't Fix Flat Flavors + +**Diagnosis tree**: +1. **Missing acid**: Most common after salt. Add lemon/lime/vinegar (start ½ tsp). +2. **Missing umami**: Add parmesan, soy, fish sauce, tomato paste, or mushroom powder. +3. **Missing aroma**: Fresh herbs, citrus zest, toasted spices, garlic oil. +4. **Over-reduced**: Flavor muted from too much reduction. Add fresh stock/water + rebalance. +5. **Textural boredom**: Flavor fine, mouthfeel monotonous. Add crunch, creaminess, or temp contrast. + +### Over-Salted Beyond Saving + +**Actions**: (1) Dilute (add unsalted liquid—stock, water, coconut milk), (2) bulk up (more base ingredients—vegetables, beans, grains), (3) acid mask (lemon/vinegar can perceptually reduce saltiness—doesn't remove, but balances), (4) fat cushion (cream, butter, or coconut milk softens salt perception). + +**If still too salty**: Repurpose (use as concentrated component in larger dish—over-salted beans → burrito filling with rice and salsa), starch absorption (serve with rice, pasta, bread—absorbs and dilutes). **Potato myth**: Raw potato does NOT absorb salt (debunked). Only dilution works. + +### Burnt vs. Charred + +**Distinction**: Charred (controlled, adds complexity—charred peppers, blackened fish) vs. burnt (acrid, overwhelms—scorched garlic, blackened onions). + +**If accidentally burnt**: (1) Remove burnt bits (don't incorporate, discard fond if burnt), (2) rinse vegetables (if edges burnt but core fine), (3) balance with sweet + fat (honey/sugar + cream can mask mild bitterness), (4) char something else intentionally (grilled lemon, toasted nuts to make it seem intentional). + +**Prevention**: Lower heat, stir more, add liquid earlier. + +### Sauce Breaking + +**Causes**: Oil added too fast (didn't emulsify), temp too high (proteins coagulated—hollandaise), over-whisking (butter emulsion can break). + +**Rescue**: (1) Vinaigrette: fresh emulsifier (mustard), slowly whisk broken sauce in, (2) hollandaise: new egg yolk in clean bowl, slowly whisk broken sauce in (dropwise first), (3) butter sauce: lower heat, add cold butter gradually while whisking, don't boil, (4) mayo: new egg yolk, slowly rebuild with broken mayo as "oil". + +--- + +## 7. Professional Kitchen Practices + +### Mise en Place Discipline + +**Philosophy**: "Everything in its place"—prep all before cooking starts. + +**Benefits**: No scrambling mid-cook (high-heat moves fast), accurate seasoning (measured in advance), clean workflow (focused on technique, not chopping). + +**Method**: (1) Read recipe completely, (2) list all ingredients and prep, (3) prep in order (longest tasks first—brines, marinades; then chopping; then measuring), (4) arrange in cooking order (left to right, or by timing), (5) prep more than needed (better extra minced garlic than run out mid-sauté). + +### Timing & Orchestration + +**Multi-dish timing**: (1) Backwards planning (start with service time, work backwards), (2) identify bottlenecks (what takes longest? what needs oven? start those first), (3) holding strategies (what can sit—braises, roasts rest; what can't—delicate fish, fried foods), (4) last-minute tasks (list for final 5 min—searing, plating, garnishing). + +**Example (3-dish dinner for 6:30 PM)**: 3:00 PM start braise (3h), 5:00 PM prep vegetables and set table, 5:45 PM roast vegetables (400°F, 30 min), 6:10 PM sear protein (8 min cook + 10 min rest), 6:20 PM reduce braising liquid to sauce and plate, 6:30 PM service. + +### Knife Skills for Efficiency + +**Core cuts**: Brunoise (1-2mm dice for mirepoix, garnish), small dice (3-4mm for aromatic base), medium dice (6-8mm for sides, soups), julienne (2mm × 2mm × 4-5cm matchstick for garnish, quick-cooking), chiffonade (ribbon for herbs, leafy greens—stack, roll, slice thin). + +**Speed techniques**: Claw grip (protect fingertips, knuckles guide blade), rocking motion (keep tip on board, rock blade), batch similar cuts (dice all onions at once), sharp knife = faster + safer (dull knife slips, requires force). + +### Tasting & Adjustment + +**When to taste**: (1) After each major ingredient addition, (2) after seasoning increments, (3) before service (final adjustment). + +**What to assess**: Salt level (enough? too much?), acid balance (bright enough? too sour?), fat/body (rich enough? too heavy?), texture (right consistency? need thickening/thinning?), temperature (taste at serving temp—affects perception). + +**Protocol**: (1) Identify primary deficiency (salt, acid, fat), (2) add small increment (¼ tsp salt, ½ tsp lemon), (3) stir, wait 30 sec (flavors distribute), (4) taste again, (5) repeat until balanced. + +--- + +## 8. Seasonal Cooking Strategies + +### Spring: Bright, Fresh, Tender + +**Philosophy**: Celebrate delicate flavors, minimal cooking, acid-forward. + +**Key ingredients**: Asparagus, peas, ramps, artichokes, spring onions, baby greens, strawberries. + +**Techniques**: Blanching (bright green vegetables), quick sautés (preserve crunch), raw preparations (pea shoots, radishes). + +**Flavor profile**: Fresh herbs (dill, tarragon, mint), lemon, light vinaigrettes, butter-based sauces (not cream-heavy). + +### Summer: Bright, Grilled, Tomato-Centric + +**Philosophy**: Showcase peak produce, outdoor cooking, minimal interference. + +**Key ingredients**: Tomatoes, corn, zucchini, peppers, eggplant, stone fruit, berries. + +**Techniques**: Grilling (char + smoke), raw salads (peak flavor needs no cooking), quick pickling (preserve abundance). + +**Flavor profile**: Basil, cilantro, lime, chili, olive oil, balsamic, smoky notes. + +### Fall: Rich, Roasted, Earthy + +**Philosophy**: Comfort, depth, caramelization, warming spices. + +**Key ingredients**: Squash, root vegetables, Brussels sprouts, apples, pears, mushrooms, game meats. + +**Techniques**: Roasting (caramelize natural sugars), braising (slow-cooked comfort), stewing (rich, thick). + +**Flavor profile**: Sage, rosemary, thyme, cinnamon, nutmeg, brown butter, cider vinegar, red wine. + +### Winter: Hearty, Braised, Preserved + +**Philosophy**: Sustenance, long-cooked, umami-rich, pantry staples. + +**Key ingredients**: Cabbage, kale, celery root, citrus, dried beans, cured meats, preserved foods. + +**Techniques**: Braising (tough cuts → tender), slow-roasting (concentrate flavors), using preserved ingredients (ferments, canned tomatoes, dried mushrooms). + +**Flavor profile**: Bay leaf, peppercorns, citrus (brightens heavy dishes), red wine, stock-based sauces, fermented funk. + +--- + +## 9. Menu Design Principles + +### Flavor Arc (Progression Through Courses) + +**Course 1 (Awaken)**: Wake up palate, stimulate appetite. Flavor: Acid-forward, fresh, bright. Example: Citrus salad, ceviche, oysters. + +**Course 2 (Explore)**: Build complexity, not too heavy. Flavor: Balanced, umami introduction. Example: Pasta with light sauce, seared fish with herb butter. + +**Course 3 (Peak)**: Richest, most complex flavors. Flavor: Umami-dominant, fat-rich, savory peak. Example: Braised short rib, duck confit, aged steak. + +**Course 4 (Refresh)**: Palate cleanser, prepare for dessert. Flavor: Acid or bitter (sorbet, cheese with bitter greens). Example: Lemon sorbet, arugula salad with aged cheese. + +**Course 5 (Satisfy)**: Sweet closure, not cloying. Flavor: Sweet with acid or bitter balance (citrus tart, dark chocolate). Example: Lemon tart, panna cotta with berry compote. + +### Textural, Temperature, & Method Diversity + +**Ensure variety across courses**: +- **Texture**: Creamy → Tender → Crispy → Soft → Crunchy +- **Temperature**: Cold → Hot → Hot → Cold → Room temp +- **Method**: Raw → Roasted → Braised → Baked + +**Within single dish**: Soft protein + crispy garnish + creamy sauce + crunchy vegetable + +### Wine/Beverage Pairing Logic + +**Principles**: (1) Match weight (light food = light wine, rich food = full-bodied), (2) match or contrast intensity, (3) acid in wine cuts fat in food, (4) sweet in wine balances spice, (5) tannin pairs with protein and fat. + +**Classic pairings**: Oysters + Champagne (acid cuts brine, bubbles refresh), salmon + Pinot Noir (light red matches fatty fish), steak + Cabernet (tannin needs fat and protein), blue cheese + Port (sweet balances funk and salt). diff --git a/skills/chef-assistant/resources/template.md b/skills/chef-assistant/resources/template.md new file mode 100644 index 0000000..fc521db --- /dev/null +++ b/skills/chef-assistant/resources/template.md @@ -0,0 +1,296 @@ +# Chef Assistant - Templates + +## Workflow + +``` +Recipe Development Progress: +- [ ] Define dish goal and flavor profile +- [ ] Identify core techniques +- [ ] Build flavor architecture +- [ ] Plan texture contrasts +- [ ] Create execution timeline +- [ ] Design plating approach +``` + +--- + +## Recipe Template + +### Recipe Name +**Cuisine**: [Type] | **Difficulty**: [Level] | **Time**: [Active] / [Total] | **Serves**: [Number] + +**Flavor Profile**: [Salt/Acid/Fat/Heat/Sweet/Umami balance] +**Texture**: [Crispy/Creamy, Hot/Cold contrasts] +**Aroma**: [Dominant notes—garlic, herbs, spices] + +### Ingredients + +**Mise en place**: +- [Ingredient] – [Amount] – [Prep: diced, minced, room temp] + +**Cooking**: [Fats, aromatics, main ingredients with purpose] +**Finishing**: [Fresh herbs, acid, flaky salt, garnish] + +**Equipment**: [Skillet, thermometer, etc.] + +### Technique Breakdown + +1. **[Technique]** (e.g., Searing) + - **Why**: Maillard crust, fond + - **How**: High heat, dry surface, don't move + - **Cues**: Golden brown, nutty aroma, releases easily + - **Precision**: 400°F+ pan, 3-4 min/side + +### Instructions + +**Step 1: Prep ([X] min)** +- Mise en place, bring proteins to room temp (30-60 min), preheat oven + +**Step 2: Build flavor base ([X] min)** +- Heat fat, add aromatics until [sensory cue], toast spices until fragrant +- **Science**: Aromatics release in fat, spices bloom + +**Step 3: Main cooking ([X] min)** +- [Instruction with technique tip, sensory checkpoint, precision temp/time] + +**Step 4: Sauce/finish ([X] min)** +- Deglaze, reduce, enrich with fat, balance salt → acid → fat + +**Step 5: Rest and plate ([X] min)** +- Rest protein [time], plate using principles below + +### Flavor Troubleshooting + +| Problem | Fix | +|---------|-----| +| Too salty | Bulk/dilute + acid + fat | +| Too sour | Fat or sweet + pinch salt | +| Too spicy | Dairy or sweet + starch | +| Flat | Salt first, then acid or umami | +| Too greasy | Acid + salt + crunch | + +### Plating + +1. **Sauce**: Under / pool / swoosh / dots +2. **Foundation**: Purée / grains (center or off-center) +3. **Hero**: Protein (center, leaning, or stacked) +4. **Accompaniments**: Sides at 3, 7 o'clock (odd numbers) +5. **Garnish**: Fresh herbs, microgreens (top, restraint) +6. **Finish**: Flaky salt, oil drizzle, citrus zest + +**Principles**: Color contrast, height, negative space (1" rim), odd numbers, clean rim + +### Cultural Context & Substitutions + +**Origin**: [Where from, traditional approach, significance] +**Variations**: [Regional differences] +**Substitutions**: If missing [ingredient] → [replacement at ratio], impact on flavor/texture +**Scaling**: Up/down notes, shortcuts for weeknight + +--- + +## Technique Breakdown Template + +### [Technique Name] + +**Category**: [Dry heat / Wet heat / Combination] | **Difficulty**: [Level] | **Equipment**: [Tools] + +**Why**: [Purpose—texture, flavor, appearance] | **When**: [Dish types] | **Science**: [Mechanism—Maillard, denaturation, etc.] + +**Temp range**: [Optimal] | **Time**: [How time affects outcome] | **Variables**: [Moisture, heat, agitation] + +### Execution + +**Prep**: [Ingredient prep, equipment setup, temp management] + +**Steps**: +1.

Hierarchy of perceptual accuracy for different chart types +5. **Mental Models & Mapping** - How prior experience shapes expectations + +--- + +## Why Perception & Attention + +### WHY This Matters + +**Core insight:** Attention is limited and selective like a spotlight - you can only focus on one thing at high resolution while periphery remains blurry. + +**Implications:** +- Visual design controls where attention goes +- Competing elements dilute attention +- Critical information must be made salient +- Users scan, they don't read everything thoroughly + +**Mental model:** Human vision is like a camera with a tiny high-resolution center (fovea covers ~1-2° of visual field) and low-resolution periphery. We rapidly move attention spotlight to important areas. + +--- + +### WHAT to Know + +#### Preattentive Processing + +**Definition:** Detection of basic visual features in under 500ms before conscious attention. + +**Preattentive Features:** +- **Color:** A single red item among gray pops out instantly +- **Form:** Unique shapes stand out (circle among squares) +- **Motion:** Moving elements grab attention automatically +- **Position:** Spatial outliers noticed quickly +- **Size:** Largest/smallest items detected fast + +**Application Rule:** +``` +Use preattentive features sparingly for 1-3 critical elements only. +Too many salient elements = visual noise = nothing stands out. +``` + +**Example:** Dashboard alert in red among gray metrics → immediate attention + +**Anti-pattern:** Everything in bright colors → overwhelm, nothing prioritized + +--- + +#### Visual Search + +**Definition:** After preattentive pop-out, users engage in serial visual search - scanning one area at a time with high acuity. + +**Predictable Patterns:** +- **F-pattern:** Text-heavy content (read top-left to top-right, then down left side, short horizontal scan middle) +- **Z-pattern:** Visual-heavy content (top-left to top-right, diagonal to bottom-left, then bottom-right) +- **Gutenberg Diagram:** Primary optical area top-left, terminal area bottom-right + +**Application Rule:** +``` +Position most important elements along scanning path: +- Top-left for primary content (both patterns start here) +- Top-right for secondary actions +- Bottom-right for terminal actions (next/submit) +``` + +**Example:** Dashboard KPIs top-left, details below, "Export" button bottom-right + +--- + +#### Attention Spotlight Trade-offs + +**Attention is zero-sum:** Effort spent on decorations is unavailable for data comprehension. + +**Rule:** Maximize attention on task-relevant elements, minimize on decorative elements. + +**Squint Test:** Blur design (squint or Gaussian blur) - can you still identify what's important?

Limit 5-7 categories. Hue lacks ordering. +- **Quantitative:** Lightness gradient (light→dark). Avoid rainbow (misleading peaks). Darkness = more. +- **Diverging:** Two-hue gradient through neutral (blue←gray→orange). Shows direction/magnitude. +- **Accessible:** Redundant coding (color + icon + label). 8% males colorblind. + +--- + +#### Perceptually Uniform Colormaps + +**Problem:** Rainbow spectrum has non-uniform perceptual steps - equal data differences don't produce equal perceived color differences. Can hide or exaggerate patterns. + +**Solution:** Use perceptually uniform colormaps: +- **Viridis** (yellow→green→blue) +- **Magma** (purple→red→yellow) +- **Plasma** (purple→orange→yellow) + +**Why:** Equal data steps = equal perceived color steps = honest representation + +**Application:** Any heatmap, choropleth map, or continuous quantitative color scale + +--- + +## Why Mental Models & Mapping + +### WHY This Matters + +**Core insight:** Users approach interfaces with preconceived notions (mental models) from past experiences.

Persuasion Frameworks + +### Cialdini's 6 Principles of Influence + +**1. Reciprocity** - People feel obligated to return favors +- **Application:** Offer value first (free tool, helpful analysis, early access) before asking +- **Example:** "We've prepared a cost-benefit analysis for your team [attached]. After reviewing, would you be open to a 15-minute conversation about implementation?" + +**2. Commitment & Consistency** - People want to act consistently with past commitments +- **Application:** Get small agreement first, then build to bigger ask +- **Example:** "You mentioned last quarter that improving customer satisfaction was a top priority. This initiative directly addresses the #1 complaint in our NPS surveys." + +**3. Social Proof** - People look to others' behavior for guidance +- **Application:** Show that similar people/companies have adopted your recommendation +- **Example:** "3 of our top 5 competitors have already implemented this approach. Salesforce saw 40% improvement in metric X within 6 months." + +**4. Authority** - People trust credible experts +- **Application:** Cite recognized experts, credentials, data sources +- **Example:** "Gartner's 2024 report identifies this as a 'must-have' capability. We've consulted with Dr. Smith, the leading researcher in this space, to design our approach." + +**5. Liking** - People say yes to those they like and relate to +- **Application:** Find common ground, acknowledge their perspective, show empathy +- **Example:** "I know the engineering team has been stretched thin with the platform migration—I've felt that pain on my own team. That's why this proposal includes dedicated support resources so you're not doing it alone." + +**6. Scarcity** - People want what's limited or exclusive +- **Application:** Highlight time constraints, limited availability, opportunity cost +- **Example:** "The vendor's discount expires Nov 30. If we don't decide by then, we'll pay 30% more in 2025, which likely means cutting scope or delaying launch." + +### Cognitive Biases to Leverage (Ethically) + +**Loss Aversion** - People fear losses more than they value equivalent gains +- ❌ Weak: "This will increase revenue by $500K" +- ✅ Strong: "Without this, we'll lose $500K in revenue to competitors who've already adopted it" + +**Anchoring** - First number mentioned sets reference point +- ❌ Weak: "This costs $100K" (sounds expensive) +- ✅ Strong: "Industry standard is $500K. We've negotiated down to $100K through our existing vendor relationship" (sounds like a deal) + +**Status Quo Bias** - People prefer current state unless change is compelling +- **Counter with:** Show status quo is unstable ("we're already losing ground") + paint vivid future state + provide clear transition path + +**Availability Heuristic** - Recent vivid examples feel more probable +- **Leverage:** Use recent concrete examples ("just last week, Customer X churned citing this exact issue") rather than abstract statistics + +**Framing Effect** - Same info presented differently drives different decisions +- ❌ Negative frame: "This approach has a 20% failure rate" +- ✅ Positive frame: "This approach succeeds 80% of the time" +- ⚠️ Use ethically: Don't hide risks, but emphasize benefits + +--- + +## 3.

Need to create clean, intuitive API that developers love using. Compete with established players (Todoist, Asana, etc.) by offering superior developer experience. + +## Context + +**What's been tried:** Initial unconstrained design produced typical REST API: +- 23 endpoints across 6 resources +- CRUD operations for everything (tasks, projects, users, tags, comments, attachments) +- Complex nested routes: `/api/v1/projects/{id}/tasks/{taskId}/comments/{commentId}/attachments` +- Auth tokens, pagination params, filtering, sorting on every endpoint +- 147-page API documentation needed + +**Why we're stuck:** API feels bloated despite being "RESTful best practices." Developers in user testing confused by too many options. Onboarding taking 2+ hours just to understand available endpoints. Defaulting to "add more endpoints for more use cases" pattern. + +**Success criteria:** +- New developer can make first successful API call in < 5 minutes +- Complete API documentation fits on single page (not 147 pages) +- Differentiated from competitor APIs (memorable, not just "another REST API") +- Supports all core use cases without sacrificing capability + +## Active Constraints + +**Constraint 1: Maximum 5 HTTP Endpoints** +- **Rationale:** Forces ruthless prioritization. Can't add endpoint for every use case. Must design for composability instead of proliferation. +- **Enforcement:** API spec cannot exceed 5 endpoint definitions. Any new endpoint requires removing an existing one. + +**Constraint 2: Single-Page Documentation** +- **Rationale:** If docs don't fit on one page, API is too complex. Forces clarity and simplicity in design. +- **Enforcement:** Entire API reference (all endpoints, params, responses, examples) must render on single scrollable page. + +**Constraint 3: No Nested Routes Beyond 2 Levels** +- **Rationale:** Prevents complexity creep from deeply nested resources. Forces flatter, more intuitive structure. +- **Enforcement:** Routes like `/projects/{id}/tasks` are allowed (2 levels). Routes like `/projects/{id}/tasks/{taskId}/comments` are forbidden (3 levels). + +## Idea Generation Process + +**Technique used:** Constraint Escalation - started with 10 endpoints, progressively reduced to find creative sweet spot + +**Volume:** Generated 27 different API designs across 4 constraint levels + +**Mindset:** Initial resistance ("5 endpoints is impossible!"), then breakthrough moment when team realized constraint forced better abstraction. + +## All Ideas Generated + +### Round 1: 10 endpoints (baseline - 50% reduction from 23) + +1.

GET /{resource}/{id} + - Retrieve specific resource by ID + - Response includes _links to related resources and actions + - Example: GET /tasks/123 includes link to project, assigned user + +5. PATCH /{resource}/{id} + - Update specific resource + - Partial updates supported (send only changed fields) + - DELETE also uses this endpoint with {"deleted": true} flag + - Atomic updates with version checking +``` + +**How constraints shaped it:** + +The 5-endpoint limit forced us to stop thinking "one endpoint per use case" and start thinking "generic operations on any resource." We couldn't add `/tasks/batch` or `/projects/{id}/tasks` or `/search` - those would exceed 5 endpoints. Instead, batch operations go through PATCH with arrays, nested resources are discovered via hypermedia links, search uses query params on GET. + +Single-page documentation constraint forced us to make the API self-documenting (GET / returns structure) rather than writing extensive docs for 23 different endpoints. The API documentation became the API itself. + +No-nesting-beyond-2-levels constraint meant we couldn't do `/projects/{id}/tasks/{taskId}/comments` - instead, comments are queried via `GET /comments?taskId=123`, which is actually simpler for client code. + +**Strengths:** +- Extreme simplicity: 5 endpoints to learn (vs 23 in original design) +- Self-documenting: GET / explains the entire API +- Extensible: Add new resources without adding endpoints +- Consistent: Same pattern for all resources (POST to create, GET to list, etc.) +- Developer-friendly: First API call can happen in 2 minutes (just GET /) +- Documentation fits on single page (literally - root response + 5 endpoint patterns) +- Hypermedia enables discovery (clients follow links rather than construct URLs) + +**Implementation notes:** + +**Resource Definitions:** +```javascript +// All resources share same interface +interface Resource { + id: string; + type: string; // "task" | "project" | "user" | "tag" + attributes: Record; + relationships?: Record; + _links: { + self: { href: string }; + [key: string]: { href: string }; + }; +} +``` + +**Example: Create task** +```bash +POST /tasks +{ + "title": "Write API docs", + "completed": false, + "projectId": "proj-123" +} + +Response: +{ + "id": "task-456", + "type": "task", + "attributes": { + "title": "Write API docs", + "completed": false + }, + "relationships": { + "project": {"data": {"type": "project", "id": "proj-123"}} + }, + "_links": { + "self": {"href": "/tasks/task-456"}, + "project": {"href": "/projects/proj-123"}, + "update": {"href": "/tasks/task-456", "method": "PATCH"}, + "complete": {"href": "/tasks/task-456", "method": "PATCH", "body": {"completed": true}} + } +} +``` + +**Example: Query with filters** +```bash +GET /tasks?filter=completed:false&filter=projectId:proj-123&sort=-dueDate&limit=20 + +Response: +{ + "data": [ /* array of task resources */ ], + "meta": { + "total": 45, + "limit": 20, + "offset": 0 + }, + "_links": { + "self": {"href": "/tasks?filter=completed:false&filter=projectId:proj-123&sort=-dueDate&limit=20"}, + "next": {"href": "/tasks?filter=completed:false&filter=projectId:proj-123&sort=-dueDate&limit=20&offset=20"} + } +} +``` + +**Example: Batch update** +```bash +PATCH /tasks/task-456 +{ + "updates": [ + {"id": "task-456", "completed": true}, + {"id": "task-789", "completed": true} + ] +} +``` + +**Risks/Limitations:** +- Generic routing may feel less "RESTful" to purists +- Requires client to understand hypermedia (though _links help) +- Query param complexity could grow (mitigate with clear documentation) +- Initial learning curve for developers used to specific endpoints + +### Solution 2: Command-Query API + +**Description:** + +Extreme minimalism using Command Query Responsibility Segregation (CQRS) pattern with only 3 endpoints. + +**The 3 Endpoints:** + +``` +1. POST /command + - Send any write operation (create, update, delete) + - Body specifies command type and parameters + - Example: + { + "command": "createTask", + "data": {"title": "Write docs", "projectId": "proj-123"} + } + +2. POST /query + - Retrieve any data (list, get, search, filter) + - Body specifies query type and parameters + - Example: + { + "query": "getTasks", + "filters": {"completed": false, "projectId": "proj-123"}, + "sort": ["-dueDate"], + "limit": 20 + } + +3. GET / + - API schema and available commands/queries + - Self-documenting entry point +``` + +**How constraints shaped it:** + +3-endpoint constraint forced us completely away from REST resource-based thinking toward command/query pattern. We couldn't map resources to endpoints, so we mapped *intentions* (commands/queries) to a single endpoint each. This wouldn't exist in unconstrained design because REST resource mapping is default pattern. + +**Strengths:** +- Ultimate minimalism: 3 endpoints total +- Clear separation of reads (queries) vs writes (commands) +- All commands versioned and auditable (event sourcing compatible) +- Extremely flexible (add new commands without new endpoints) + +**Risks/Limitations:** +- Not REST (breaks HTTP verb semantics) +- POST for queries feels wrong to REST purists +- Loses HTTP caching benefits (GET query would cache better) +- Requires comprehensive command/query documentation + +### Solution 3: Smart Defaults API + +**Description:** + +5 endpoints with "intelligent defaults" that make common use cases zero-config while allowing full customization. + +**The 5 Endpoints:** + +``` +1. GET / + - Entry point + documentation + +2. POST /{resource} + - Create with smart defaults + - Example: POST /tasks with just {"title": "Write docs"} + - Auto-assigns: current user, default project, due date (24h from now) + +3. GET /{resource} + - Defaults to useful view (not everything) + - GET /tasks → uncompleted tasks for current user, sorted by due date + - Full query: GET /tasks?view=all&user=*&completed=* + +4. GET /{resource}/{id} + - Retrieve specific item + - Response includes related items intelligently + - GET /tasks/123 → includes project, assigned user, recent comments (last 5) + +5. POST /{resource}/{id}/action + - Semantic actions instead of PATCH + - POST /tasks/123/complete (vs PATCH with {"completed": true}) + - POST /tasks/123/assign?userId=456 + - POST /tasks/123/move?projectId=789 +``` + +**How constraints shaped it:** + +5-endpoint limit meant we couldn't have separate endpoints for common actions (complete task, assign task, move task, etc.). Instead of PATCH with various payloads, we created semantic action endpoint that's more intuitive for developers. The constraint forced us to think: "What actions do developers actually want?" vs "What CRUD operations exist?" + +**Strengths:** +- Developer-friendly (semantic actions match mental model) +- Smart defaults reduce API calls (get task includes related data) +- Progressive disclosure (simple cases are simple, complex cases possible) + +**Risks/Limitations:** +- "Actions" endpoint could grow complex +- Magic defaults might surprise users +- Less "pure REST" than Solution 1 + +## Evaluation + +**Constraint compliance:** ✓ All solutions respect 5-endpoint max (Solution 2 uses only 3), single-page documentation, and no deep nesting + +**Novelty assessment:** All solutions are novel (score: 5/5) +- Solution 1: Hypermedia-driven design is uncommon in modern APIs +- Solution 2: Command-Query pattern breaks REST entirely (radical) +- Solution 3: Semantic actions vs CRUD is differentiated +- None would exist with unconstrained design (would default to 23-endpoint CRUD API) + +**Problem fit:** Solutions address original challenge +- **Developer onboarding < 5 min:** ✓ GET / self-documents, simple patterns +- **Single-page docs:** ✓ All solutions achievable with 1-page documentation +- **Differentiation:** ✓ All three approaches are memorable vs typical REST APIs +- **Supports use cases:** ✓ Generic patterns support all original use cases + +**Actionability:** All three designs can be implemented immediately + +## Creative Breakthrough Explanation + +The constraint-driven breakthrough happened when we stopped asking "How do we fit 23 endpoints into 5?" and started asking "How do we design an API that only needs 5 endpoints?" + +**Thinking pattern broken:** +- Old pattern: "Each use case needs an endpoint" (additive thinking) +- New pattern: "Each endpoint should handle multiple use cases" (multiplicative thinking) + +**Unexpected angle revealed:** +Minimalism isn't about removing features - it's about better abstraction. Generic `/{resource}` pattern with query params provides MORE flexibility than specific endpoints, not less. + +**Why wouldn't this exist in unconstrained brainstorming:** +With no constraints, we defaulted to REST "best practices" which led to endpoint proliferation. The 5-endpoint constraint forced us to question whether those "best practices" were actually best for developer experience. Turns out, simplicity beats completeness for DX. + +**Real-world validation:** +- Stripe API: Uses resource patterns (minimal endpoints) +- GitHub API v3→v4: Moved from REST to GraphQL (single endpoint) for exactly this reason +- Twilio API: Consistent resource patterns across all products + +The constraint helped us discover patterns that successful APIs already use. + +## Next Steps + +**Decision:** Implement Solution 1 (Hypermedia-Driven Minimalist API) as primary design + +**Rationale:** +- Maintains REST principles (HTTP verbs matter) +- Self-documenting (GET / returns structure) +- Most familiar to developers (resource-based) +- Proven pattern (HAL, JSON:API specs exist) +- Best balance of minimalism and usability + +**Immediate actions:** +1. Create OpenAPI spec for 5 endpoints (TODAY) +2. Build prototype implementation (THIS WEEK) +3. User test with 5 developers (NEXT WEEK) +4. Measure onboarding time (target: < 5 minutes to first successful call) +5. Write single-page documentation (NEXT WEEK) + +**Success metrics:** +- Time to first API call (target: < 5 min) +- Documentation page count (target: 1 page) +- Developer satisfaction (NPS after onboarding) +- Comparison: Our 5 endpoints vs competitor's 20+ endpoints + +## Self-Assessment (using rubric) + +**Constraint Integrity (5/5):** Rigorous adherence. Solution 1 uses exactly 5 endpoints. Documentation will fit on single page (verified with draft). No nesting beyond 2 levels. + +**Constraint-Creativity Causality (5/5):** Clear causality. Generic `/{resource}` pattern exists ONLY because 5-endpoint limit forbid per-use-case endpoints. Hypermedia self-documentation exists because single-page constraint forced self-documenting design. + +**Idea Volume & Quality (5/5):** Generated 15+ distinct API designs across 4 constraint levels. Top 3 solutions all score 5/5 novelty. + +**Problem-Solution Fit (5/5):** All solutions hit success criteria: < 5 min onboarding, single-page docs, differentiation, full capability. + +**Actionability (5/5):** Solution 1 includes OpenAPI spec, code examples, implementation notes, and testing plan. Can implement immediately. + +**Technical Rigor (5/5):** Solutions are architecturally sound. Hypermedia pattern is proven (HAL/JSON:API specs). Resource abstraction is clean. + +**Differentiation (5/5):** Design differentiates through minimalism (5 vs 23 endpoints), self-documentation (GET /), and developer experience focus. + +**Risk Honesty (4/5):** Acknowledged risks (hypermedia learning curve, query param complexity).

With unlimited budget, we'd run conventional ads and never think to turn our limitation into our story. The $500 constraint became the entire narrative hook - it's not a bug, it's the feature. Platform constraint (Twitter + GitHub) forced us to storytelling formats (threads + repos) rather than polished landing pages. Organic-only constraint meant the story itself must be compelling enough to spread. + +**Strengths:** +- Authentic and relatable (most startups are resource-constrained) +- Built-in narrative tension ("Can they succeed on $500?") +- Educational value (others learn from the journey) +- Differentiates through transparency (competitors hide their budgets) +- Meta-viral (the campaign IS the story) +- Generates daily content without feeling promotional + +**Implementation notes:** + +**Week 1:** Launch announcement +- Tweet: "We're launching a B2B SaaS product with a $500 budget.

Competitors hide their budgets and processes; we make ours the whole campaign. + +**Why wouldn't this exist in unconstrained brainstorming:** With $50K budget, we'd run LinkedIn ads and content marketing - conventional but forgettable. The $500 constraint forced us to think "What can ONLY we do with $500 that creates more attention than $50K in ads?" Answer: Turn the limitation into the story. + +## Next Steps + +**Decision:** Execute Solution 1 ("The $500 Startup") as primary campaign + +**Rationale:** +- Highest narrative tension (can they succeed?) +- Generates daily content (30 days of touchpoints) +- Most authentic (real constraints, real challenges) +- Educational value outlasts 30 days (becomes permanent resource) + +**Immediate actions:** +1.

Diagnosing Creative Blocks + +Before designing constraints, diagnose WHY creativity is stuck: + +### Block Type 1: Abundance Paralysis +**Symptoms:** Too many options, can't decide, everything feels possible but nothing feels right +**Root cause:** Unlimited freedom creates decision anxiety +**Best constraint types:** Resource (force scarcity), Format (force specificity) +**Example constraint:** "Choose from exactly 3 options" or "$500 budget only" + +### Block Type 2: Pattern Fixation +**Symptoms:** All ideas feel similar, defaulting to "what we always do", conventional thinking +**Root cause:** Mental habits, industry best practices dominating, lack of novelty pressure +**Best constraint types:** Rule-based (forbid the pattern), Historical (different era), Perspective (different audience) +**Example constraint:** "Cannot use industry-standard approach" or "Design as if it's 1950" + +### Block Type 3: Complexity Creep +**Symptoms:** Ideas keep getting more elaborate, feature bloat, "we need to add X and Y and Z" +**Root cause:** Mistaking complexity for sophistication, no forcing function for simplicity +**Best constraint types:** Format (force brevity), Resource (force efficiency), Technical (force optimization) +**Example constraint:** "Explain in 10 words" or "Must work on 1990s hardware" + +### Block Type 4: Resource Anxiety +**Symptoms:** "We can't do anything with this budget/time/team", defeatism, giving up before ideating +**Root cause:** Viewing limitation as blocker rather than creative fuel +**Best constraint types:** Resource Inversion (make limitation the feature), Success Stories (show constraint-driven wins) +**Example constraint:** "Create marketing campaign that showcases our tiny budget as advantage" + +### Block Type 5: Incremental Thinking +**Symptoms:** Ideas are "better" but not "different", improvements without breakthroughs +**Root cause:** Optimization mindset, risk aversion, lack of permission for radical ideas +**Best constraint types:** Forced Connection (force novelty), Forbidden Element (force workarounds), Extreme (force dramatic shift) +**Example constraint:** "Combine your product with [random unrelated concept]" or "No gradual improvements allowed" + +### Block Type 6: Stakeholder Gridlock +**Symptoms:** Every idea gets shot down, conflicting requirements, "we can't satisfy everyone" +**Root cause:** Trying to please all stakeholders creates bland compromises +**Best constraint types:** Audience (design for ONE stakeholder only), Perspective (extreme user), Polarity (embrace the conflict) +**Example constraint:** "Design exclusively for power users, ignore novices" or "Optimize for speed OR quality, not both" + +--- + +## 2. Strategic Constraint Design + +Frameworks for designing constraints that unlock creativity: + +### Framework 1: The Counterfactual Principle +Design constraints that are the **opposite** of current assumptions. + +**Current assumption → Constraint:** +- "We need more features" → "Maximum 3 features" +- "We need more time" → "Ship in 48 hours" +- "We need bigger budget" → "Spend $100 only" +- "We need expert team" → "Design for novice execution" +- "We need to add" → "Remove 50% of current" + +### Framework 2: The Subtraction Cascade +Remove assumed "essentials" one at a time to reveal what's truly necessary. + +**Process:** +1. List all assumed essentials (budget, time, team, features, marketing, etc.) +2. For each essential, ask: "What if we had zero X?" +3. Generate 5 ideas for zero-X scenario +4. Identify which "essential" assumptions are actually optional + +**Example:** E-commerce site +- What if zero budget for ads? → Viral/organic/referral strategies emerge +- What if zero product photos? → Text-driven, story-driven commerce emerges +- What if zero checkout process? → One-click, subscription, or auto-replenish models emerge + +### Framework 3: The Constraint Ladder +Progressive constraint tightening to find the creative sweet spot. + +**Level 1 (Gentle):** Constraint is noticeable but comfortable +**Level 2 (Challenging):** Constraint forces rethinking but still manageable +**Level 3 (Extreme):** Constraint seems impossible, forces radical creativity +**Level 4 (Paralyzing):** Constraint too tight, generates zero ideas + +**Example:** Content creation +- L1: "Write in 500 words" (comfortable) +- L2: "Write in 100 words" (challenging) +- L3: "Write in 10 words" (extreme, forces breakthroughs) +- L4: "Write in 3 words" (paralysis, too tight) + +Aim for Level 2-3. If hitting Level 4, back off one level. + +### Framework 4: The Medium-as-Constraint +Force creativity by changing the medium. + +**Original medium → Constraint medium:** +- Strategy document → Strategy as recipe +- Product roadmap → Roadmap as movie trailer script +- Technical docs → Docs as children's book +- Business proposal → Proposal as Shakespearean sonnet +- Data presentation → Data as visual art installation + +Medium shift breaks habitual communication patterns. + +--- + +## 3. Psychology of Constraints + +Why constraints boost creativity (science-backed principles): + +### Principle 1: Cognitive Load Reduction +**Theory:** Unlimited options overwhelm working memory. Constraints reduce cognitive load, freeing mental energy for creativity. +**Application:** When team is overwhelmed, add constraints to reduce decision space. +**Example:** "Choose from 3 pre-selected options" vs "anything is possible" + +### Principle 2: Breaking Automaticity +**Theory:** Brains default to habitual patterns (energy-efficient). Constraints force conscious, deliberate thinking. +**Application:** When stuck in patterns, add constraints that forbid the habit. +**Example:** "No bullet points" forces different communication structure + +### Principle 3: Psychological Reactance +**Theory:** Being told "you can't" triggers motivation to prove you can (within the rules). +**Application:** Frame constraints as challenges, not limitations. +**Example:** "Design without using any images" becomes a creative challenge + +### Principle 4: Permission Through Limitation +**Theory:** Constraints provide "excuse" for radical ideas ("we HAD to because of X"). +**Application:** Use constraints to create safety for risky ideas. +**Example:** "$100 budget" gives permission for guerrilla marketing tactics + +### Principle 5: Forced Combination +**Theory:** Constraints force novel combinations that wouldn't occur in unconstrained thinking. +**Application:** Use constraints that require merging unrelated concepts. +**Example:** "Explain technical architecture using cooking metaphors only" + +--- + +## 4. Advanced Idea Generation + +Techniques beyond basic listing: + +### Technique 1: Parallel Constraint Exploration +Run multiple constraint sets simultaneously, compare results. + +**Process:** +1. Choose 3 different constraint types +2. Set timer for 10 minutes per constraint +3. Generate ideas for Constraint A (10 min) +4. Switch to Constraint B (10 min) +5. Switch to Constraint C (10 min) +6. Compare: which constraint produced most novel ideas? +7. Double down on that constraint type + +**Example:** Logo design +- Constraint A: 3 colors maximum → 8 ideas +- Constraint B: Circles only → 12 ideas +- Constraint C: Black/white only → 15 ideas (winner) +- → Continue with black/white constraint + +### Technique 2: Constraint Rotation Sprints +Rapid cycling through different constraints to prevent fixation. + +**Process:** +1. Set 5-minute timer +2. Generate ideas for Constraint 1 +3. When timer rings, IMMEDIATELY switch to Constraint 2 +4. Generate for 5 minutes, switch to Constraint 3 +5. After 3 constraints, review all ideas +6. Select strongest, refine for 10 minutes + +Prevents over-thinking any single constraint. + +### Technique 3: Meta-Constraint Thinking +Apply constraints to the constraint-selection process itself. + +**Meta-constraints:** +- "Must use constraint type I've never tried" +- "Must combine 2 opposite constraints" (e.g., "minimal" + "maximal") +- "Must choose constraint that scares me" +- "Must use constraint from unrelated domain" (e.g., music constraints for business problem) + +### Technique 4: The "Yes, But What If" Ladder +Progressive constraint tightening with idea building. + +**Process:** +1. Start with idea from loose constraint +2. "Yes, but what if [tighter constraint]?" → Adapt idea +3. "Yes, but what if [even tighter]?" → Adapt again +4. Continue until idea breaks or becomes brilliant + +**Example:** Marketing campaign +- Idea: Email newsletter +- Yes, but what if no images? → Text-only newsletter with strong copy +- Yes, but what if 50 words max? → Punchy, Hemingway-style newsletter +- Yes, but what if one sentence only? → Twitter-thread-style micro-newsletter +- Yes, but what if 6 words only? → Six-word story newsletter (breaks through!) + +### Technique 5: Constraint Archaeology +Mine history for proven constraint-driven successes, adapt to current challenge. + +**Historical constraint successes:** +- Twitter's 140 characters → Brevity revolution +- Haiku's 5-7-5 syllables → Poetic concision +- Dr. Seuss's 50-word challenge (Green Eggs and Ham) → Children's lit classic +- Dogme 95 film rules → Cinema movement +- Helvetica font (limited character set) → Timeless design + +**Process:** +1. Research historical constraint-driven successes in any domain +2. Extract the constraint principle +3. Adapt to your challenge +4. Test if same principle unlocks creativity + +--- + +## 5. Constraint Combination Patterns + +Strategic ways to layer multiple constraints: + +### Pattern 1: Complementary Pairing +Combine constraints that reinforce each other. + +**Examples:** +- Resource + Format: "$100 budget" + "One-page proposal" +- Time + Technical: "48-hour deadline" + "Use existing tools only" +- Audience + Medium: "For 5-year-olds" + "Visual only, no text" + +**Why it works:** Constraints push in same direction, compounding effect. + +### Pattern 2: Tension Pairing +Combine constraints that conflict, forcing creative resolution. + +**Examples:** +- "Minimal design" + "Maximum information density" +- "Professional tone" + "No corporate jargon" +- "Fast execution" + "Zero technical debt" + +**Why it works:** Tension forces innovation to satisfy both. + +### Pattern 3: Progressive Layering +Add constraints sequentially, not all at once. + +**Process:** +1. Start with Constraint 1 → Generate 10 ideas +2. Add Constraint 2 → Adapt best ideas or generate new ones +3. Add Constraint 3 → Further refinement + +**Example:** Product launch +1.

Troubleshooting + +When constraints don't produce creativity: + +### Problem 1: Constraint Too Loose +**Symptom:** Ideas feel conventional, no creative tension +**Diagnosis:** Constraint isn't actually constraining behavior +**Fix:** Escalate constraint (see Section 6). Make it tighter until you feel resistance. + +### Problem 2: Constraint Too Tight +**Symptom:** Zero ideas generated, complete paralysis, frustration +**Diagnosis:** Constraint exceeded breakthrough zone into paralysis +**Fix:** Back off one level. Use Constraint Ladder (Framework 3) to find sweet spot. + +### Problem 3: Wrong Constraint Type +**Symptom:** Lots of ideas but none address the original block +**Diagnosis:** Constraint doesn't counter the diagnosed creative block +**Fix:** Return to Section 1 (Diagnosing Creative Blocks). Match constraint type to block type. + +### Problem 4: Constraint Not Enforced +**Symptom:** Ideas "bend" the constraint or ignore it entirely +**Diagnosis:** Treating constraint as suggestion rather than rule +**Fix:** Make constraint enforcement explicit. Reject any idea that violates constraint. + +### Problem 5: Too Many Constraints +**Symptom:** Overwhelmed, don't know where to start, ideas satisfy some constraints but not others +**Diagnosis:** Over-constrained (4+ simultaneous constraints) +**Fix:** Reduce to 1-2 constraints maximum. Use Progressive Layering (Pattern 3) if multiple constraints needed. + +### Problem 6: Arbitrary Constraint +**Symptom:** Constraint feels random, no clear purpose +**Diagnosis:** Constraint wasn't strategically designed +**Fix:** Use Strategic Constraint Design frameworks (Section 2). Constraint should counter specific block. + +### Problem 7: Evaluating Too Early +**Symptom:** Only 3-5 ideas generated before giving up +**Diagnosis:** Judging ideas before achieving volume +**Fix:** Force 20+ ideas minimum before any evaluation. Quantity first, quality later. + +### Problem 8: Missing the Causality +**Symptom:** Solutions are good but could exist without the constraint +**Diagnosis:** Not truly constraint-driven creativity +**Fix:** Ask: "Would this idea exist in unconstrained brainstorming?" If yes, keep generating. If no, you've found constraint-driven creativity. + +--- + +## 8.

Month 1: Master Constraint A (e.g., "Ship weekly") +2. Month 2: Add Constraint B (e.g., "+ under 100 lines") +3. Month 3: Add Constraint C (e.g., "+ zero dependencies") +4. Result: Constraint-driven expertise + +### Pattern: The Anti-Portfolio +Document what you're NOT doing (constraint as strategy). + +**Example:** Y Combinator's anti-portfolio +- Constraint: "We passed on X because [reason]" +- Result: Learning from constraint violations +- Outcome: Refine constraint strategy + +--- + +## 9.

Define margins for axes: `{top: 20, right: 20, bottom: 30, left: 40}`. Calculate inner width/height: `width - margin.left - margin.right`. See [Getting Started](resources/getting-started.md#setup-svg-container). + +**Step 2: Load and parse data** + +Use `d3.csv('data.csv')` for external files or define data array directly. Parse dates with `d3.timeParse('%Y-%m-%d')` for time series. Convert strings to numbers for CSV data using conversion function. See [Getting Started](resources/getting-started.md#loading-data). + +**Step 3: Create scales** + +Choose scale types based on data: `scaleBand` (categorical), `scaleTime` (temporal), `scaleLinear` (quantitative). Set domains from data using `d3.extent()`, `d3.max()`, or manual ranges. Set ranges from SVG dimensions. See [Scales & Axes](resources/scales-axes.md#scale-types). + +**Step 4: Generate axes** + +Create axis generators: `d3.axisBottom(xScale)`, `d3.axisLeft(yScale)`. Append g elements positioned with transforms. Call axis generators: `.call(axis)`. Customize ticks with `.ticks()`, `.tickFormat()`. See [Scales & Axes](resources/scales-axes.md#creating-axes). + +**Step 5: Bind data and create visual elements** + +Use data join pattern: `svg.selectAll(type).data(array).join(type)`. Set attributes using scales and accessor functions: `.attr('x', d => xScale(d.category))`. For line charts, use `d3.line()` generator. For scatter plots, create circles with `cx`, `cy`, `r` attributes. See [Selections & Data Joins](resources/selections-datajoins.md#data-join-pattern) and [Shapes & Layouts](resources/shapes-layouts.md). + +**Step 6: Style and add interactivity** + +Apply colors: `.attr('fill', ...)`, `.attr('stroke', ...)`.

This makes visualization reusable for any dataset. See [Workflows](resources/workflows.md#update-pattern). + +**Step 2: Update scale domains** + +Recalculate domains when data range changes: `yScale.domain([0, d3.max(newData, d => d.value)])`. Update axes with transition: `svg.select('.y-axis').transition().duration(500).call(yAxis)`. See [Selections & Data Joins](resources/selections-datajoins.md#updating-scales). + +**Step 3: Re-bind data with key function** + +Use key function for object constancy: `.data(newData, d => d.id)`. Ensures elements track data items, not array positions. Critical for correct transitions. See [Selections & Data Joins](resources/selections-datajoins.md#key-functions). + +**Step 4: Add transitions to join** + +Insert `.transition().duration(500)` before attribute updates. Specify easing with `.ease(d3.easeCubicOut)`. For custom enter/exit effects, use enter/exit functions in `.join()`. See [Transitions & Interactions](resources/transitions-interactions.md#basic-transitions). + +**Step 5: Update attributes with new values** + +Set positions/sizes using updated scales: `.attr('y', d => yScale(d.value))`, `.attr('height', d => height - yScale(d.value))`. Transitions animate from old to new values. See [Common Patterns](resources/common-patterns.md#bar-chart-template). + +**Step 6: Trigger update on data change** + +Call `update(newData)` when data changes: button clicks, timers (`setInterval`), WebSocket messages, API responses.

Minimum standard: Average score ≥ 3.5. + +## Schema Types + +Choose based on use case and technology: + +**Relational (SQL) Schema** +- **Best for:** Transactional systems (OLTP), strong consistency, complex queries with joins +- **Pattern:** Normalized tables, foreign keys, ACID transactions +- **Example use cases:** E-commerce orders, banking transactions, HR systems +- **Key decision:** Normalization level (3NF for consistency vs denormalized for read performance) + +**Document/NoSQL Schema** +- **Best for:** Flexible/evolving structure, high write throughput, denormalized reads +- **Pattern:** Nested documents, embedded relationships, no joins +- **Example use cases:** Content management, user profiles, event logs +- **Key decision:** Embed vs reference (embed for 1-to-few, reference for 1-to-many) + +**Graph Schema (Ontology)** +- **Best for:** Complex relationships, traversal queries, semantic reasoning, knowledge graphs +- **Pattern:** Nodes (entities), edges (relationships), properties on both +- **Example use cases:** Social networks, fraud detection, recommendation engines, scientific research +- **Key decision:** Property graph vs RDF triples + +**Event/Time-Series Schema** +- **Best for:** Audit logs, metrics, IoT data, append-only data +- **Pattern:** Immutable events, time-based partitioning, aggregation tables +- **Example use cases:** User activity tracking, monitoring, financial transactions +- **Key decision:** Raw events vs pre-aggregated summaries + +**Dimensional (Data Warehouse) Schema** +- **Best for:** Analytics (OLAP), aggregations, historical reporting +- **Pattern:** Fact tables + dimension tables (star/snowflake schema) +- **Example use cases:** Business intelligence, sales analytics, customer 360 +- **Key decision:** Star schema (denormalized) vs snowflake (normalized dimensions) + +## Common Patterns + +**Pattern: Entity Lifecycle Modeling** +Track entity state changes explicitly. Example: Order (draft → pending → confirmed → shipped → delivered → completed/cancelled). Include status field, timestamps for each state, and transitions table if history needed. + +**Pattern: Soft Deletes** +Never physically delete records - add `deletedAt` timestamp. Allows data recovery, audit compliance, and referential integrity. Filter `WHERE deletedAt IS NULL` in queries. + +**Pattern: Polymorphic Associations** +Entity relates to multiple types. Example: Comment can be on Post or Photo. Options: (1) separate foreign keys (commentableType + commentableId), (2) junction tables per type, (3) single table inheritance. + +**Pattern: Temporal/Historical Data** +Track changes over time. Options: (1) Effective/expiry dates per record, (2) separate history table, (3) event sourcing (store all changes as events). Choose based on query patterns. + +**Pattern: Multi-tenancy** +Isolate data per customer. Options: (1) Separate databases (strong isolation), (2) Shared schema with tenantId column (efficient), (3) Separate schemas in same DB (balance). Add tenantId to all queries if shared. + +**Pattern: Hierarchies** +Model trees/nested structures. Options: (1) Adjacency list (parentId), (2) Nested sets (left/right values), (3) Path enumeration (materialized path), (4) Closure table (all ancestor-descendant pairs).

Why? +- What's the "do nothing" or status quo option? + +**To surface must-haves:** +- Are there absolute dealbreakers? (Budget cap, timeline requirement, compliance need) +- Which constraints are flexible vs rigid? + +## Criterion Types + +Common categories for criteria (adapt to your decision): + +**Financial Criteria:** +- Upfront cost, ongoing cost, ROI, payback period, budget impact +- Typical weight: 20-40% (higher for cost-sensitive decisions) + +**Performance Criteria:** +- Speed, quality, reliability, scalability, capacity, throughput +- Typical weight: 30-50% (higher for technical decisions) + +**Risk Criteria:** +- Implementation risk, reversibility, vendor lock-in, technical debt, compliance risk +- Typical weight: 10-25% (higher for enterprise/regulated environments) + +**Strategic Criteria:** +- Alignment with goals, future flexibility, competitive advantage, market positioning +- Typical weight: 15-30% (higher for long-term decisions) + +**Operational Criteria:** +- Ease of use, maintenance burden, training required, integration complexity +- Typical weight: 10-20% (higher for internal tools) + +**Stakeholder Criteria:** +- Team preference, user satisfaction, executive alignment, customer impact +- Typical weight: 5-15% (higher for change management contexts) + +## Weighting Approaches + +**Method 1: Direct Allocation (simplest)** +Stakeholders assign percentages totaling 100%.

Advanced Weighting Methods + +### Analytic Hierarchy Process (AHP) + +**When to use:** High-stakes decisions with contentious priorities, need rigorous justification + +**Process:** + +1. **Create pairwise comparison matrix:** For each pair, rate 1-9 (1=equal, 3=slightly more important, 5=moderately, 7=strongly, 9=extremely) +2. **Calculate weights:** Normalize columns, average rows +3. **Check consistency:** CR < 0.10 acceptable (use online AHP calculator: bpmsg.com/ahp/ahp-calc.php) + +**Example:** Comparing Cost, Performance, Risk, Ease pairwise yields weights: Performance 55%, Risk 20%, Cost 15%, Ease 10% + +**Advantage:** Rigorous, forces logical consistency in pairwise judgments. + +### Swing Weighting + +**When to use:** Need to justify weights based on value difference, not just importance + +**Process:** + +1. **Baseline:** Imagine all criteria at worst level +2. **Swing:** For each criterion, ask "What value does moving from worst to best create?" +3. **Rank swings:** Which swing creates most value? +4. **Assign points:** Give highest swing 100 points, others relative to it +5. **Convert to weights:** Normalize points to percentages + +**Example:** + +| Criterion | Worst → Best Scenario | Value of Swing | Points | Weight | +|-----------|----------------------|----------------|--------|--------| +| Performance | 50ms → 5ms response | Huge value gain | 100 | 45% | +| Cost | $100K → $50K | Moderate value | 60 | 27% | +| Risk | High → Low risk | Significant value | 50 | 23% | +| Ease | Hard → Easy to use | Minor value | 10 | 5% | + +**Total points:** 220 → **Weights:** 100/220=45%, 60/220=27%, 50/220=23%, 10/220=5% + +**Advantage:** Focuses on marginal value, not abstract importance. Reveals if criteria with wide option variance should be weighted higher. + +### Multi-Voting (Group Weighting) + +**When to use:** Group of 5-15 stakeholders needs to converge on weights + +**Process:** + +1. **Round 1 - Individual allocation:** Each person assigns 100 points across criteria +2. **Reveal distribution:** Show average and variance for each criterion +3. **Discuss outliers:** Why did some assign 40% to Cost while others assigned 10%? +4. **Round 2 - Revised allocation:** Re-allocate with new information +5. **Converge:** Repeat until variance is acceptable or use average + +**Example:** + +| Criterion | Round 1 Avg | Round 1 Variance | Round 2 Avg | Round 2 Variance | +|-----------|-------------|------------------|-------------|------------------| +| Cost | 25% | High (±15%) | 30% | Low (±5%) | +| Performance | 40% | Medium (±10%) | 38% | Low (±4%) | +| Risk | 20% | Low (±5%) | 20% | Low (±3%) | +| Ease | 15% | High (±12%) | 12% | Low (±4%) | + +**Convergence achieved** when variance <±5% for all criteria. + +--- + +## 3. Score Calibration & Normalization + +### Handling Different Scorer Tendencies + +**Problem:** Some scorers are "hard graders" (6-7 range), others are "easy graders" (8-9 range). This skews results. + +**Solution: Z-score normalization** + +**Step 1: Calculate each scorer's mean and standard deviation** + +Scorer A: Gave scores [8, 9, 7, 8] → Mean=8, SD=0.8 +Scorer B: Gave scores [5, 6, 4, 6] → Mean=5.25, SD=0.8 + +**Step 2: Normalize each score** + +Z-score = (Raw Score - Scorer Mean) / Scorer SD + +**Step 3: Re-scale to 1-10** + +Normalized Score = 5.5 + (Z-score × 1.5) + +**Result:** Scorers are calibrated to same scale, eliminating grading bias. + +### Dealing with Missing Data + +**Scenario:** Some alternatives can't be scored on all criteria (e.g., vendor A won't share cost until later). + +**Approach 1: Conditional matrix** + +Score available criteria only, note which are missing. Once data arrives, re-run matrix. + +**Approach 2: Pessimistic/Optimistic bounds** + +Assign worst-case and best-case scores for missing data. Run matrix twice: +- Pessimistic scenario: Missing data gets low score (e.g., 3) +- Optimistic scenario: Missing data gets high score (e.g., 8) + +If same option wins both scenarios → Decision is robust. If different winners → Missing data is decision-critical, must obtain before deciding. + +### Non-Linear Scoring Curves + +**Problem:** Not all criteria are linear. E.g., cost difference between $10K and $20K matters more than $110K vs $120K. + +**Solution: Apply utility curves** + +**Diminishing returns curve** (Cost, Time): +- Score = 10 × (1 - e^(-k × Cost Improvement)) +- k = sensitivity parameter (higher k = faster diminishing returns) + +**Threshold curve** (Must meet minimum): +- Score = 0 if below threshold +- Score = 1-10 linear above threshold + +**Example:** Load time criterion with 2-second threshold: +- Option A: 1.5s → Score = 10 (below threshold = great) +- Option B: 3s → Score = 5 (above threshold, linear penalty) +- Option C: 5s → Score = 1 (way above threshold) + +--- + +## 4. Advanced Sensitivity Analysis + +### Monte Carlo Sensitivity + +**When to use:** High uncertainty in scores, want to understand probability distribution of outcomes + +**Process:** + +1. **Define uncertainty ranges** for each score + - Option A Cost score: 6 ± 2 (could be 4-8) + - Option A Performance: 9 ± 0.5 (could be 8.5-9.5) + +2. **Run simulations** (1000+ iterations): + - Randomly sample scores within uncertainty ranges + - Calculate weighted total for each option + - Record winner + +3. **Analyze results:** + - Option A wins: 650/1000 = 65% probability + - Option B wins: 300/1000 = 30% probability + - Option C wins: 50/1000 = 5% probability + +**Interpretation:** +- **>80% win rate:** High confidence in decision +- **50-80% win rate:** Moderate confidence, option is likely but not certain +- **<50% win rate:** Low confidence, gather more data or consider decision is close call + +**Tools:** Excel (=RANDBETWEEN or =NORM.INV), Python (numpy.random), R (rnorm) + +### Scenario Analysis + +**When to use:** Future is uncertain, decisions need to be robust across scenarios + +**Process:** + +1. **Define scenarios** (typically 3-4): + - Best case: Favorable market conditions + - Base case: Expected conditions + - Worst case: Unfavorable conditions + - Black swan: Unlikely but high-impact event + +2. **Adjust criterion weights or scores per scenario:** + +| Scenario | Cost Weight | Performance Weight | Risk Weight | +|----------|-------------|--------------------|-------------| +| Best case | 20% | 50% | 30% | +| Base case | 30% | 40% | 30% | +| Worst case | 40% | 20% | 40% | + +3. **Run matrix for each scenario**, identify winner + +4. **Evaluate robustness:** + - **Dominant option:** Wins in all scenarios → Robust choice + - **Scenario-dependent:** Different winners → Need to assess scenario likelihood + - **Mixed:** Wins in base + one other → Moderately robust + +### Threshold Analysis + +**Question:** At what weight does the decision flip? + +**Process:** + +1. **Vary one criterion weight** from 0% to 100% (keeping others proportional) +2. **Plot total scores** for all options vs. weight +3. **Identify crossover point** where lines intersect (decision flips) + +**Example:** + +When Performance weight < 25% → Option B wins (cost-optimized) +When Performance weight > 25% → Option A wins (performance-optimized) + +**Insight:** Current weight is 40% for Performance. Decision is robust unless Performance drops below 25% importance. + +**Practical use:** Communicate to stakeholders: "Even if we reduce Performance priority to 25% (vs current 40%), Option A still wins. Decision is robust." + +--- + +## 5. Group Decision Facilitation + +### Delphi Method (Asynchronous Consensus) + +**When to use:** Experts geographically distributed, want to avoid groupthink, need convergence without meetings + +**Process:** + +**Round 1:** +- Each expert scores options independently (no discussion) +- Facilitator compiles scores, calculates median and range + +**Round 2:** +- Share Round 1 results (anonymous) +- Experts see median scores and outliers +- Ask experts to re-score, especially if they were outliers (optional: provide reasoning) + +**Round 3:** +- Share Round 2 results +- Experts make final adjustments +- Converge on consensus scores (median or mean) + +**Convergence criteria:** Standard deviation of scores <1.5 points per criterion + +**Example:** + +| Option | Criterion | R1 Scores | R1 Median | R2 Scores | R2 Median | R3 Scores | R3 Median | +|--------|-----------|-----------|-----------|-----------|-----------|-----------|-----------| +| A | Cost | [5, 7, 9, 6] | 6.5 | [6, 7, 8, 6] | 6.5 | [6, 7, 7, 7] | **7** | + +**Advantage:** Avoids dominance by loudest voice, reduces groupthink, allows reflection time. + +### Nominal Group Technique (Structured Meeting) + +**When to use:** In-person or virtual meeting, need structured discussion to surface disagreements + +**Process:** + +1. **Silent generation (10 min):** Each person scores options independently +2. **Round-robin sharing (20 min):** Each person shares one score and rationale (no debate yet) +3. **Discussion (30 min):** Debate differences, especially outliers +4. **Re-vote (5 min):** Independent re-scoring after hearing perspectives +5. **Aggregation:** Calculate final scores (mean or median) + +**Facilitation tips:** +- Enforce "no interruptions" during round-robin +- Time-box discussion to avoid analysis paralysis +- Focus debate on criteria with widest score variance + +### Handling Persistent Disagreement + +**Scenario:** After multiple rounds, stakeholders still disagree on weights or scores. + +**Options:** + +**1. Separate matrices by stakeholder group:** + +Run matrix for Engineering priorities, Sales priorities, Executive priorities separately. Present all three results. Highlight where recommendations align vs. differ. + +**2. Escalate to decision-maker:** + +Present divergence transparently: "Engineering weights Performance at 60%, Sales weights Cost at 50%. Under Engineering weights, Option A wins. Under Sales weights, Option B wins. Recommendation: [Decision-maker] must adjudicate priority trade-off." + +**3. Multi-criteria satisficing:** + +Instead of optimizing weighted sum, find option that meets minimum thresholds on all criteria. This avoids weighting debate. + +**Example:** Option must score ≥7 on Performance AND ≤$50K cost AND ≥6 on Ease of Use. Find options that satisfy all constraints. + +--- + +## 6. Matrix Variations & Extensions + +### Weighted Pros/Cons Matrix +Hybrid: Add "Key Pros/Cons/Dealbreakers" columns to matrix for qualitative context alongside quantitative scores. + +### Multi-Phase Decision Matrix +**Phase 1:** High-level filter (simple criteria) → shortlist top 3 +**Phase 2:** Deep-dive (detailed criteria) → select winner +Avoids analysis paralysis by not deep-diving on all options upfront. + +### Risk-Adjusted Matrix +For uncertain scores, use expected value: (Optimistic + 4×Most Likely + Pessimistic) / 6 +Accounts for score uncertainty in final weighted total. + +--- + +## 7. Common Failure Modes & Recovery + +| Failure Mode | Symptoms | Recovery | +|--------------|----------|----------| +| **Post-Rationalization** | Oddly specific weights, generous scores for preferred option | Assign weights BEFORE scoring, use third-party facilitator | +| **Analysis Paralysis** | >10 criteria, endless tweaking, winner changes repeatedly | Set deadline, time-box criteria (5 max), use satisficing rule | +| **Garbage In, Garbage Out** | Scores are guesses, no data sources, false confidence | Flag uncertainties, gather real data, acknowledge limits | +| **Criterion Soup** | Overlapping criteria, scorer confusion | Consolidate redundant criteria, define each clearly | +| **Spreadsheet Error** | Calculation mistakes, weights don't sum to 100% | Use templates with formulas, peer review calculations | + +--- + +## 8.

After all pairs, Performance has 4 wins (40%), Cost has 2 wins (20%), etc. + +### Technique 3: Stakeholder Averaging (Group Decisions) +Multiple stakeholders with different priorities.

Choose Resolution ≥ IV if interactions matter. + +4. **Check design balance**: Ensure orthogonality (factors are uncorrelated in design matrix). Correlation > 0.3 reduces precision and interpretability. + +5. **Define response precisely**: Use objective, quantitative, repeatable measurements. Avoid subjective scoring unless calibrated with multiple raters. + +6. **Justify sample size**: Run power analysis to ensure design can detect meaningful effect sizes with acceptable Type II error risk (β ≤ 0.20). + +7. **Document assumptions**: State expected effect magnitudes, interaction assumptions, noise variance estimates.

Each inner array run is repeated at all outer array conditions. + +**Example: L₈ inner × L₄ outer** (8 control combinations × 4 noise conditions = 32 runs): + +**Inner array (control factors A, B, C)**: + +| Run | A | B | C | +|-----|---|---|---| +| 1 | -1 | -1 | -1 | +| 2 | -1 | -1 | +1 | +| ... | ... | ... | ... | +| 8 | +1 | +1 | +1 | + +**Outer array (noise factors N₁, N₂)**: + +| Noise | N₁ | N₂ | +|-------|----|----| +| 1 | -1 | -1 | +| 2 | -1 | +1 | +| 3 | +1 | -1 | +| 4 | +1 | +1 | + +**Data collection**: For each inner run, measure response Y at all 4 noise conditions. Calculate mean (Ȳ) and variance (s²) or signal-to-noise ratio (SNR). + +**Signal-to-Noise Ratios**: +- **Larger-is-better**: SNR = -10 log₁₀(Σ(1/Y²)/n) +- **Smaller-is-better**: SNR = -10 log₁₀(ΣY²/n) +- **Target-is-best**: SNR = 10 log₁₀(Ȳ²/s²) + +**Analysis**: Choose control factor settings that maximize SNR (robust to noise) while achieving target mean. + +**Two-step optimization**: +1. Maximize SNR to reduce variability +2. Adjust mean to target using control factors that don't affect SNR + +--- + +## 4. Optimal Designs + +**When to use**: Irregular factor space (constraints, categorical factors, unequal ranges), custom run budget, or standard designs don't fit. + +### D-Optimal Designs + +**Criterion**: Minimize determinant of (X'X)⁻¹ (maximize information, minimize variance of coefficient estimates). + +**Algorithm**: Computer-generated. Start with candidate set of all feasible runs, select subset that maximizes |X'X|. + +**Use cases**: +- Mixture experiments with additional process variables +- Constrained factor spaces (e.g., temperature + pressure can't both be high) +- Irregular grids (e.g., existing data points + new runs) +- Unequal factor ranges + +**Software**: Use R (AlgDesign package), JMP, Design-Expert, or Python (pyDOE). + +### A-Optimal and G-Optimal + +**A-optimal**: Minimize average variance of predictions (trace of (X'X)⁻¹). +**G-optimal**: Minimize maximum variance across design space (minimax criterion). + +**Choice**: D-optimal for parameter estimation, G-optimal for prediction across entire space, A-optimal for average prediction quality. + +--- + +## 5.

Use D-optimal design for constrained mixture space. + +--- + +## 6. Split-Plot Designs + +**When to use**: Some factors are hard to change (e.g., temperature requires hours to stabilize), others are easy to change. Randomizing all factors fully is impractical or expensive. + +### Structure + +**Whole-plot factors**: Hard to change (temperature, batch, supplier) +**Subplot factors**: Easy to change (concentration, time, operator) + +**Design**: Randomize whole-plot factors at top level, randomize subplot factors within each whole-plot level. + +**Example: 2² split-plot** (Temperature = whole-plot, Time = subplot, 2 replicates): + +| Whole-plot | Temp | Subplot | Time | Run order | +|------------|------|---------|------|-----------| +| 1 | Low | 1 | Short | 1 | +| 1 | Low | 2 | Long | 2 | +| 2 | High | 3 | Short | 4 | +| 2 | High | 4 | Long | 3 | +| (Replicate block 2) + +**Analysis**: Mixed model with whole-plot error and subplot error terms. Whole-plot factors tested with lower precision (fewer degrees of freedom). + +**Trade-off**: Allows practical execution when full randomization impossible, but reduces statistical power for hard-to-change factors. + +--- + +## 7. Sequential Experimentation + +**Philosophy**: Learn iteratively, adapt design based on results. Minimize total runs while maximizing information. + +### Stage 1: Screening + +**Objective**: Reduce 10-20 candidates to 3-5 critical factors. +**Design**: Plackett-Burman or 2^(k-p) fractional factorial (Resolution III-IV). +**Runs**: 12-20. +**Output**: Ranked factor list, effect sizes with uncertainty. + +### Stage 2: Steepest Ascent/Descent + +**Objective**: Move quickly toward optimal region using main effects from screening. +**Method**: Calculate path of steepest ascent (gradient = effect estimates). Run experiments along this path until response stops improving. +**Example**: If screening finds temp effect = +10, pressure effect = +5, move in direction (temp: +2, pressure: +1). + +### Stage 3: Factorial Optimization + +**Objective**: Explore region around best settings from steepest ascent, estimate interactions. +**Design**: 2^k full factorial or Resolution V fractional factorial with 3-5 factors. +**Runs**: 16-32. +**Output**: Optimal settings, interaction effects, linear model. + +### Stage 4: Response Surface Refinement + +**Objective**: Fit curvature, find true optimum. +**Design**: CCD or Box-Behnken centered at best settings from Stage 3. +**Runs**: 15-20. +**Output**: Quadratic model, stationary point (optimum), contour plots. + +### Stage 5: Confirmation + +**Objective**: Validate predicted optimum. +**Design**: 3-5 replication runs at predicted optimal settings. +**Output**: Confidence interval for response at optimum. If prediction interval contains observed mean, model validated. + +**Total runs example**: Screening (16) + Steepest ascent (4) + Factorial (16) + RSM (15) + Confirmation (3) = 54 runs. Compare to one-shot full factorial for 10 factors = 1024 runs. + +--- + +## 8. Analysis Techniques + +### Effect Estimation + +**Factorial designs**: Estimate main effect of factor A as: Effect(A) = (Ȳ₊ - Ȳ₋) where Ȳ₊ = mean response when A is high, Ȳ₋ = mean when A is low. + +**Interaction effect**: Effect(AB) = [(Ȳ₊₊ + Ȳ₋₋) - (Ȳ₊₋ + Ȳ₋₊)] / 2 + +**Standard error**: SE(effect) = 2σ/√n, where σ estimated from replicates or center points. + +### ANOVA + +**Purpose**: Test statistical significance of effects. +**Null hypothesis**: Effect = 0. +**Test statistic**: F = MS(effect) / MS(error), compare to F-distribution. +**Significance**: p < 0.05 (or chosen α level) → reject H₀, effect is significant. + +### Regression Modeling + +**Linear model**: Y = β₀ + β₁x₁ + β₂x₂ + β₁₂x₁x₂ + ε +**Quadratic model** (RSM): Y = β₀ + Σβᵢxᵢ + Σβᵢᵢxᵢ² + Σβᵢⱼxᵢxⱼ + ε + +**Fit**: Least squares (minimize Σ(Yᵢ - Ŷᵢ)²). +**Assessment**: R², adjusted R², RMSE, residual plots. + +### Residual Diagnostics + +**Check assumptions**: +1. **Normal probability plot**: Residuals should fall on straight line. Non-normality indicates transformation needed. +2. **Residuals vs fitted**: Random scatter around zero. Funnel shape indicates non-constant variance (transform Y). +3. **Residuals vs run order**: Random. Trend indicates time drift, lack of randomization. +4. **Residuals vs factors**: Random. Pattern indicates missing interaction or curvature. + +**Transformations**: Log(Y) for multiplicative effects, √Y for count data, 1/Y for rate data, Box-Cox for data-driven choice. + +### Optimization + +**Contour plots**: Visualize response surface, identify optimal region, assess tradeoffs. +**Desirability functions**: Multi-response optimization. Convert each response to 0-1 scale (0 = unacceptable, 1 = ideal). Maximize geometric mean of desirabilities. +**Canonical analysis**: Find stationary point (∂Y/∂xᵢ = 0), classify as maximum, minimum, or saddle point based on eigenvalues of Hessian matrix. + +--- + +## 9. Sample Size and Power Analysis + +**Before designing experiment, determine required runs**: + +**Power**: Probability of detecting true effect if it exists (1 - β). Standard: power ≥ 0.80. + +**Effect size (δ)**: Minimum meaningful difference. Example: "Must detect 10% yield improvement." + +**Noise (σ)**: Process variability. Estimate from historical data, pilot runs, or engineering judgment. + +**Formula for factorial designs**: n ≥ 2(Zα/2 + Zβ)²σ² / δ² per cell. + +**Example**: Detect δ = 5 units, σ = 3 units, α = 0.05, power = 0.80. +- n ≥ 2(1.96 + 0.84)²(3²) / 5² = 2(7.84)(9) / 25 ≈ 6 replicates per factor level combination. + +**For screening**: Use effect sparsity assumption. If testing 10 factors, expect 2-3 active. Size design to detect large effects (1-2σ). + +**Software**: Use G*Power, R (pwr package), JMP, or online calculators. + +--- + +## 10. Common Pitfalls and Solutions + +**Pitfall 1: Ignoring confounding in screening designs** +- **Problem**: Plackett-Burman confounds main effects with 2-way interactions. If interactions exist, main effect estimates are biased. +- **Solution**: Use only when sparsity-of-effects applies (most interactions negligible). Follow up ambiguous results with Resolution IV/V design or fold-over. + +**Pitfall 2: Extrapolating beyond design region** +- **Problem**: Response surface models are local approximations. Predicting outside tested factor ranges is unreliable. +- **Solution**: Expand design if optimum appears outside current region. Run steepest ascent, then new RSM centered on improved region. + +**Pitfall 3: Inadequate replication** +- **Problem**: Without replicates, cannot estimate pure error or test lack-of-fit. +- **Solution**: Always include 3-5 center point replicates. For critical experiments, replicate entire design (2-3 times). + +**Pitfall 4: Changing protocols mid-experiment** +- **Problem**: Breaks orthogonality, confounds design structure with time. +- **Solution**: Complete design as planned. If protocol change necessary, analyze before/after separately or treat as blocking factor. + +**Pitfall 5: Treating categorical factors as continuous** +- **Problem**: Assigning arbitrary numeric codes (-1, 0, +1) to unordered categories (e.g., Supplier A/B/C) implies ordering that doesn't exist. +- **Solution**: Use indicator variables (dummy coding) or separate experiments for each category level. diff --git a/skills/design-of-experiments/resources/template.md b/skills/design-of-experiments/resources/template.md new file mode 100644 index 0000000..1d0a2bf --- /dev/null +++ b/skills/design-of-experiments/resources/template.md @@ -0,0 +1,395 @@ +# Design of Experiments - Template + +## Workflow + +Copy this checklist and track your progress: + +``` +DOE Template Progress: +- [ ] Step 1: Define experiment objective +- [ ] Step 2: List factors and levels +- [ ] Step 3: Select design type +- [ ] Step 4: Generate design matrix +- [ ] Step 5: Randomize and document protocol +- [ ] Step 6: Finalize experiment plan +``` + +**Step 1: Define experiment objective** + +Specify what you're trying to learn (screening, optimization, response surface, robust design), primary response metric(s), and success criteria.

Or B in some phases, A in others. +- **Example**: "Speed vs Quality" → **Synthesis**: Iterate fast early (speed), stabilize before launch (quality). Time-box exploration, then shift to refinement. +- **When to use**: Positions optimize for different lifecycle stages or contexts. + +**Pattern 2: Conditional Synthesis (Both, Contextual)** +- **Structure**: A in these situations, B in those situations. Define decision criteria. +- **Example**: "Centralized vs Decentralized" → **Synthesis**: Centralize strategy/standards/shared resources, decentralize execution/tactics/experiments. Clear escalation criteria for edge cases. +- **When to use**: Positions are optimal in different scenarios or scopes. + +**Pattern 3: Dimensional Separation (Both, Different Axes)** +- **Structure**: Optimize A on one dimension, B on another orthogonal dimension. +- **Example**: "Simple vs Powerful" → **Synthesis**: Simple by default (80% use cases), powerful for power users (progressive disclosure, advanced mode). Complexity optional, not mandatory. +- **When to use**: Tradeoff is false—can achieve both on different dimensions simultaneously. + +**Pattern 4: Higher-Order Principle (Transcend via Meta-Goal)** +- **Structure**: Both A and B are means to same end. Find better means. +- **Example**: "Build vs Buy" → **Synthesis**: Neither—rent/SaaS. Or: Build core differentiator, buy commodity. Higher principle: Maximize value creation per dollar/hour. +- **When to use**: Binary options are tactics, not ends. Reframe around shared ultimate goal. + +**Pattern 5: Compensating Controls (Accept A's Risk, Mitigate with B's Safeguard)** +- **Structure**: Lean toward A, add B's protections as guardrails. +- **Example**: "Move Fast vs Prevent Errors" → **Synthesis**: Move fast with automated testing, staged rollouts, quick rollback. Accept some errors, contain blast radius. +- **When to use**: One position clearly better for primary goal, other provides risk mitigation. + +## Guardrails + +**Critical requirements:** + +1. **Steelman, don't strawman**: Present each position as its adherents would recognize. Ask: "Would someone who holds this view agree this is a fair representation?" If no, strengthen it further. + +2. **Identify principles, not just preferences**: Go deeper than "Side A wants X, Side B wants Y." Find WHY they want it. What value do they optimize for? Freedom? Safety? Speed? Equity? Efficiency? + +3. **Synthesis must transcend, not just compromise**: Splitting the difference (50% A, 50% B) is usually weak. Good synthesis finds new option C that honors both principles at higher level. "Both-and" thinking, not "either-or" averaging. + +4. **Make tradeoffs explicit**: Every synthesis has costs. State what you gain AND what you sacrifice vs pure positions. Don't pretend synthesis is "best of both with no downsides." + +5. **Avoid false equivalence**: Steelmanning doesn't mean both sides are equally correct. One position may have stronger arguments/evidence. Synthesis should reflect this (lean toward stronger position, add safeguards from weaker). + +6. **Check for false dichotomy**: Some "debates" are manufactured. Both A and B may be bad options. Ask: "Is this actually a binary choice, or are we missing option C/D/E?" + +7. **Test synthesis with adversarial roles**: Before finalizing, inhabit each original position and critique the synthesis.

Common Fallacies in Dialectical Reasoning + +### Strawman (The Problem Steelmanning Solves) + +**Definition**: Misrepresenting opponent's position to make it easier to attack. +**Example**: "Position A wants speed, so they don't care about quality." +**Fix**: Steelman: "Position A prioritizes speed because early market entry captures compounding advantages, accepting higher initial defect risk as a calculated tradeoff." + +### False Dichotomy + +**Definition**: Framing as binary choice when other options exist. +**Example**: "We must choose growth OR profitability." +**Detection**: Ask: "Are these actually mutually exclusive? Can we do both sequentially, conditionally, or on different dimensions?" +**Fix**: Synthesis via temporal, conditional, or dimensional separation patterns. + +### False Equivalence + +**Definition**: Treating unequal positions as equally valid. +**Example**: "Both sides have good points" when one position has stronger evidence. +**Fix**: Steelman both, but acknowledge asymmetry. Synthesis can lean heavily toward stronger position while incorporating weaker position's safeguards. + +### Slippery Slope + +**Definition**: Assuming small step inevitably leads to extreme outcome without justification. +**Example**: "If we allow any technical debt, we'll end up with unmaintainable codebase." +**Fix**: Identify intermediate stopping points, decision criteria, compensating controls. "Technical debt is acceptable if: (1) repayment plan exists, (2) debt tracked publicly, (3) quarterly budget for paydown." + +### Appeal to Extremes + +**Definition**: Judging position by worst-case misuse rather than typical application. +**Example**: "Decentralization leads to chaos" (judging by anarchy rather than reasonable autonomy). +**Fix**: Steelman with realistic implementation, boundaries, guardrails. "Decentralized execution with centralized strategy and escalation paths." + +### Begging the Question + +**Definition**: Assuming the conclusion in the premise. +**Example**: "We should centralize because centralization works better." +**Detection**: Check if warrant is circular.

(Empirical question—creates vulnerability for adversaries too) + +**Higher-order principle**: "Maximize security for law-abiding citizens" + +**Synthesis**: No backdoors (protects against authoritarian abuse and adversarial exploitation), but strong metadata analysis, international cooperation on criminal activity, investment in other investigative techniques.

Pick two dominant positions (A vs B) +2. Synthesize to C' +3. Compare C' vs remaining position C +4. Synthesize to C'' +5. Repeat until all positions incorporated + +**Limitation**: Order-dependent. Different pairing order may yield different synthesis. + +### Approach 2: Principle Clustering + +1. Map all positions to underlying principles +2. Group positions by shared principles +3. Identify principle conflicts (not position conflicts) +4. Synthesize at principle level +5. Derive concrete approach from principle synthesis + +**Example**: + +**Debate**: How to structure engineering team (100 engineers)? + +**Position A**: Centralized platform team builds shared services, product teams consume +**Position B**: Fully autonomous product teams, each owns full stack +**Position C**: Matrix org, engineers report to tech lead (for skills) and product manager (for direction) +**Position D**: Rotate engineers across teams quarterly for knowledge sharing + +**Principle mapping**: +- A values: Consistency, reuse, economies of scale (instrumental) +- B values: Autonomy, speed, end-to-end ownership (instrumental) +- C values: Skill development, career growth (instrumental) +- D values: Knowledge distribution, bus factor reduction (instrumental) + +**Terminal goal (all positions)**: Maximize product delivery velocity AND quality + +**Synthesis**: Hybrid model— +- Platform team for true shared infrastructure (data pipeline, auth, payments—things with network effects or compliance requirements) +- Product teams own full stack for product-specific features (autonomy where it matters) +- Guilds for skill development (engineers self-organize by discipline—frontend, backend, data) +- 6-month rotations optional for L3-L4 engineers (knowledge sharing without mandating churn) + +**Result**: Incorporates elements from all four positions, structured by principle (platform for scale, autonomy for speed, guilds for growth, optional rotation for knowledge). + +--- + +## 5. Nested Dialectics + +**Use when**: One of the "positions" is itself a synthesis of sub-positions. Positions have internal contradictions. + +### Structure + +**Position A**: Synthesis of A1 vs A2 +**Position B**: Synthesis of B1 vs B2 +**Meta-synthesis**: Resolve A vs B at higher level + +### Example + +**Debate**: How should AI companies handle safety vs capability development? + +**Position A (Safety-first)**: Is itself a synthesis of: +- A1: Pause all development until alignment solved +- A2: Develop capabilities slowly with extensive testing + +**Position B (Capability-first)**: Is itself a synthesis of: +- B1: Race to AGI (winner determines future) +- B2: Develop capabilities, use them to solve alignment + +**Meta-synthesis approach**: + +1. **Steelman sub-positions** (A1, A2, B1, B2) +2. **Identify that A vs B is false dichotomy**: Actually four positions with different combinations of beliefs about: + - How solvable is alignment? (A1: very hard, A2/B2: tractable, B1: solve after) + - What are risks of delay? (A: manageable, B1: existential, B2: medium) +3. **Reframe around cruxes**: Not safety vs capability, but **beliefs about alignment difficulty and delay risks** +4. **Synthesis based on empirical assessment**: If alignment progress stalls (trigger), slow capability development (A2). If alignment progresses faster than expected (trigger), maintain pace (B2). Never pure A1 (pause is unilateral disadvantage) or B1 (race without guardrails is reckless). + +**Result**: Conditional synthesis that responds to empirical evidence, not fixed binary. + +--- + +## 6. Empirical vs Normative Questions + +**Use when**: Debate mixes factual questions (what IS) with value questions (what SHOULD BE). + +### Separation Strategy + +1. **Decompose debate** into empirical claims vs normative claims +2. **Empirical claims**: Resolvable via evidence (in principle). Highlight these as **cruxes**—if evidence changes, does position change? +3. **Normative claims**: Value judgments. Require principle-level resolution, not evidence. +4. **Synthesize separately**: Agree on facts where possible, then resolve value conflict conditional on facts. + +### Example + +**Debate**: Should we implement remote-first work policy? + +**Mixed arguments**: +- Position A: "Remote work hurts productivity" (empirical) + "Companies should maximize productivity" (normative) +- Position B: "Remote work improves wellbeing" (empirical) + "Employee wellbeing matters more than marginal productivity" (normative) + +**Separation**: + +**Empirical questions** (resolvable with data): +1. Does remote work reduce productivity? (Measure: output metrics, project completion, code quality) +2. Does remote work improve wellbeing? (Measure: retention, satisfaction scores, burnout rates) +3. Is there variance by role? (e.g., individual contributors vs managers) + +**Normative questions** (value judgments): +1. How should we weight productivity vs wellbeing? +2. What about hiring advantages (global talent pool)? +3. Long-term effects on culture, mentorship, serendipity? + +**Synthesis approach**: +- **Resolve empirical questions first**: Run 6-month experiment, measure metrics +- **Conditional synthesis based on data**: + - If productivity unchanged or improves → Remote-first (preserves wellbeing, no cost) + - If productivity declines < 10% but wellbeing/retention improves → Remote-first (accept tradeoff) + - If productivity declines > 10% → Hybrid (2-3 days office for collaboration, 2-3 remote for focus) +- **Re-evaluate quarterly**: Track metrics, adjust policy + +**Result**: Separates empirical cruxes from value questions, makes synthesis conditional on evidence. + +--- + +## 7. Power Dynamics and Conflicts of Interest + +**Use when**: Debate involves parties with different power, resources, or incentives. "Disagreement" may be conflict of interest, not idea conflict. + +### Detection + +**Signs of power dynamics**: +- One position benefits speaker/advocate materially (financial, status, control) +- Asymmetric stakes (one side risks much more) +- Historical power imbalance between advocates +- Debate framing obscures who benefits ("rising tide lifts all boats" when boats are different sizes) + +### Approach + +1. **Make power dynamics explicit**: Who benefits from each position? What are material stakes? +2. **Separate ideas from interests**: Steelman arguments independent of advocate motives +3. **Synthesis must address structural issues**: Can't resolve via "better ideas" if problem is power imbalance +4. **Compensating mechanisms**: If synthesis leans toward powerful party's position, include safeguards for less powerful + +### Example + +**Debate**: Should gig economy platforms classify workers as employees vs independent contractors? + +**Position A (Contractor status)**: Flexibility, entrepreneurial freedom, lower costs (enables more work) +**Position B (Employee status)**: Benefits, job security, labor protections + +**Power dynamic**: Platforms have massive information/resource advantage, legal teams, lobbying. Workers individually have minimal bargaining power. + +**Steelman both arguments** (independent of power): +- A: Flexibility IS valuable for many workers (students, retirees, side hustlers) +- B: Protections ARE necessary for full-time gig workers (no healthcare, no unemployment insurance) + +**Synthesis that addresses power**: +- **Classification by hours**: <20 hrs/week = contractor (flexibility preserved), ≥20 hrs/week = employee (protections for full-timers) +- **Portable benefits**: Industry-wide benefits fund (platforms contribute per worker-hour, workers access regardless of hours) +- **Collective bargaining**: Workers can organize without classification change (addresses power imbalance directly) + +**Result**: Synthesis recognizes power dynamic, doesn't just "split difference on ideas." + +--- + +## 8. Synthesis Validation Techniques + +### Adversarial Testing + +**Method**: Inhabit each original position and attack the synthesis. + +**Questions to ask as Position A partisan**: +- Does synthesis abandon my core principle? +- Is this really "synthesis" or capitulation to Position B? +- What tradeoffs am I being asked to accept that Position B isn't? + +**Repeat as Position B partisan.** + +**Pass criteria**: Synthesis survives critique from both sides, or critiques cancel out (each side sees it as slight lean toward other, suggesting balance). + +### Edge Case Analysis + +**Method**: Test synthesis with extreme scenarios. + +**Example**: "Move fast with guardrails" synthesis + +**Edge cases**: +- High-risk domain (healthcare, finance) → Guardrails insufficient? +- Novel technology → Guardrails unknown? +- Aggressive competitor → Speed advantage evaporates? + +**Evaluation**: Does synthesis break down in edge cases? If yes, refine with conditional logic ("In high-risk domains, prioritize guardrails over speed"). + +### Unintended Consequences + +**Method**: Consider second-order effects, perverse incentives, long-term dynamics. + +**Example**: "Profitable growth" synthesis (grow as fast as unit economics allow) + +**Unintended consequences**: +- Focus on profitable channels may miss future market shifts (addressable market shrinks) +- Discipline to say no may calcify into risk-aversion +- LTV:CAC metric may be gamed (optimize metric, not underlying economics) + +**Fix**: Add monitoring ("Review addressable market quarterly"), decision criteria ("Experiment with 10% budget in unproven channels"), and metric audits ("Validate LTV assumptions annually"). + +### Synthesis Stability Test + +**Question**: Is synthesis stable, or does it collapse back to Position A/B under pressure? + +**Example**: "Centralize strategy, decentralize execution" + +**Pressure test**: +- Strategy team starts specifying execution details → Collapse to centralization +- Execution teams ignore strategy → Collapse to full autonomy +- Gray-zone decisions escalate constantly → Synthesis unworkable + +**Fix**: Define clear boundaries ("Strategy sets goals and constraints, not tactics"), escalation criteria ("Escalate if execution conflicts with cross-team dependency"), and feedback loop ("Execution teams input to strategy quarterly"). + +--- + +## 9. Advanced Synthesis Patterns + +### Pattern 6: Principle Inversion + +**Structure**: Both positions optimize for same principle but in opposite ways. Synthesis finds third approach to principle. + +**Example**: "Maximize developer productivity" +- Position A: Remove all process (friction kills productivity) +- Position B: Standardize everything (consistency enables productivity) + +**Synthesis**: Identify which types of friction help vs hurt. Remove ceremony (status meetings, approval chains) that wastes time. Add structure (linters, type systems, templates) that reduces cognitive load. Not "some process," but "automate what can be automated, remove what can't." + +### Pattern 7: Time-Horizon Mismatch + +**Structure**: Positions optimize for different time horizons. Synthesis balances short-term and long-term. + +**Example**: Technical debt +- Position A: Never take debt (compound interest kills you) +- Position B: Always optimize for shipping (future is uncertain) + +**Synthesis**: Allow debt with explicit interest rate. "Accept debt if repayment cost < 2x initial cost AND payback within 6 months. Track debt-hours, allocate 20% of sprint to paydown." + +### Pattern 8: Stakeholder Rotation + +**Structure**: Different stakeholders have different needs. Synthesis rotates optimization target. + +**Example**: Product priorities +- Customer wants features +- Engineering wants technical excellence +- Business wants revenue + +**Synthesis**: Quarterly rotation. Q1: Customer (ship requested features). Q2: Engineering (refactor, test coverage, performance). Q3: Business (monetization, growth experiments). Q4: Integration (synthesize learnings). Over 12 months, all stakeholders served. + +### Pattern 9: Threshold-Based Switching + +**Structure**: Position A below threshold, Position B above threshold. + +**Example**: Meeting culture +- Position A: Async-first (meetings are waste) +- Position B: High-bandwidth sync (Zoom for everything) + +**Synthesis**: Use async for <5 people OR routine updates. Use sync for ≥5 people AND novel/contentious discussion. Threshold-based decision rule. + +### Pattern 10: Modular Synthesis + +**Structure**: Different parts of system optimize differently. + +**Example**: Software architecture +- Core services: Optimize for reliability (test coverage, formal methods, slow deploys) +- Experimentation layer: Optimize for speed (feature flags, canary rollouts, fast iteration) +- Infrastructure: Optimize for cost (spot instances, autoscaling) + +**Synthesis**: Not one-size-fits-all. Different modules, different optimization criteria, unified by interfaces and observability. diff --git a/skills/dialectical-mapping-steelmanning/resources/template.md b/skills/dialectical-mapping-steelmanning/resources/template.md new file mode 100644 index 0000000..210baa2 --- /dev/null +++ b/skills/dialectical-mapping-steelmanning/resources/template.md @@ -0,0 +1,398 @@ +# Dialectical Mapping & Steelmanning - Template + +## Workflow + +Copy this checklist and track your progress: + +``` +Dialectical Mapping Progress: +- [ ] Step 1: Frame the debate and clarify binary +- [ ] Step 2: Steelman Position A +- [ ] Step 3: Steelman Position B +- [ ] Step 4: Create tradeoff matrix +- [ ] Step 5: Synthesize third way +- [ ] Step 6: Finalize document +``` + +**Step 1: Frame the debate** + +Identify topic, two positions, and why it's framed as binary.

Bad: "Don't you think our UI is confusing?" Good: "Walk me through using this feature. What happened?" + +2. **Focus on past behavior, not hypotheticals**: What people did reveals truth; what they say they'd do is often wrong. Bad: "Would you use this feature?" Good: "Tell me about the last time you needed to do X." + +3. **Use "show me" not "tell me"**: Actual behavior > described behavior. Ask to screen-share, demonstrate current workflow, show artifacts (spreadsheets, tools). + +4. **Recruit right participants**: Screen carefully. Wrong participants = wasted time. Define inclusion/exclusion criteria, use screening survey. + +5. **Sample size appropriate for method**: Interviews: 5-15 for themes to emerge. Surveys: 100+ for statistical significance, 30+ per segment if comparing. + +6. **Avoid confirmation bias**: Actively look for disconfirming evidence. If 9/10 interviews support hypothesis, focus heavily on the 1 that doesn't. + +7. **Record and transcribe (with permission)**: Memory is unreliable. Record interviews, transcribe for analysis. Take notes as backup. + +8. **Analyze systematically**: Don't cherry-pick quotes that support preferred conclusion. Use thematic coding, count themes, present contradictory evidence. + +**Common pitfalls:** + +- ❌ **Asking "would you" questions**: Hypotheticals are unreliable.

Always specify Population, Intervention, Comparator, Outcome, Timeframe explicitly. Avoid "does X work?" without defining for whom, compared to what, and measuring which outcomes. + +2. **Match study design to question type**: RCTs answer therapy questions (causal inference). Cohort studies answer prognosis. Cross-sectional studies answer diagnosis. Case-control studies answer rare harm or etiology. Don't claim causation from observational data or use case series for treatment effects. + +3. **Prioritize patient-important outcomes over surrogates**: Surrogate endpoints (biomarkers, lab values) don't always correlate with patient outcomes. Focus on mortality, morbidity, symptoms, function, quality of life. Only use surrogates if validated relationship to patient outcomes exists. + +4. **Assess bias systematically, not informally**: Use validated tools (Cochrane RoB 2, ROBINS-I, QUADAS-2) not subjective judgment. Bias assessment affects certainty of evidence and clinical recommendations. Common biases: selection bias, performance bias (lack of blinding), detection bias, attrition bias, reporting bias. + +5. **Apply GRADE to rate certainty of evidence**: Don't conflate study design with certainty. RCTs start as high certainty but can be downgraded (serious limitations, inconsistency, indirectness, imprecision, publication bias). Observational studies start as low but can be upgraded (large effect, dose-response, residual confounding reducing effect). + +6. **Distinguish statistical significance from clinical importance**: p < 0.05 doesn't mean clinically meaningful. Consider minimal clinically important difference (MCID), absolute risk reduction, number needed to treat (NNT). Small p-value with tiny effect size is statistically significant but clinically irrelevant. + +7. **Assess external validity and applicability**: Evidence from selected trial populations may not apply to your patient. Consider PICO match (are your patients similar?), setting differences (tertiary center vs community), intervention feasibility, patient values and preferences. + +8. **State limitations and certainty explicitly**: All evidence has limitations. Specify what's uncertain, where evidence gaps exist, and how this affects confidence in recommendations. Avoid overconfident claims not supported by evidence quality. + +**Common pitfalls:** + +- ❌ **Treating all RCTs as high quality**: RCTs can have serious bias (inadequate randomization, unblinded, high attrition). Always assess bias. +- ❌ **Ignoring heterogeneity in meta-analysis**: High I² (>50%) suggests important differences across studies. Explore sources (population, intervention, outcome definition) before pooling. +- ❌ **Confusing association with causation**: Observational studies show association, not causation. Residual confounding is always possible. +- ❌ **Using composite outcomes uncritically**: Composite endpoints (e.g., "death or MI or hospitalization") obscure which component drives effect. Report components separately. +- ❌ **Accepting industry-funded evidence uncritically**: Pharmaceutical/device company-sponsored trials may have bias (outcome selection, selective reporting). Assess for conflicts of interest. +- ❌ **Over-interpreting subgroup analyses**: Most subgroup effects are chance findings.

Consider searching trial registries for unpublished studies. + +### Upgrade Factors (Observational Studies Only) + +**1. Large Effect** +- **Upgrade +1**: RR > 2 or < 0.5 (based on consistent evidence, no plausible confounders) +- **Upgrade +2**: RR > 5 or < 0.2 ("very large effect") +- **Example**: Smoking → lung cancer (RR ~20) upgraded from low to moderate or high + +**2. Dose-Response Gradient** +- **Upgrade +1**: Increasing exposure associated with increasing risk/benefit in consistent pattern +- **Example**: More cigarettes/day → higher lung cancer risk + +**3. All Plausible Confounders Would Reduce Observed Effect** +- **Upgrade +1**: Despite confounding working against finding effect, effect still observed +- **Example**: Healthy user bias would reduce observed benefit, yet benefit still seen + +### Final Certainty Rating + +**High** (⊕⊕⊕⊕): Very confident true effect is close to estimate. Further research very unlikely to change conclusion. + +**Moderate** (⊕⊕⊕○): Moderately confident. True effect is likely close to estimate, but could be substantially different. Further research may change conclusion. + +**Low** (⊕⊕○○): Limited confidence. True effect may be substantially different. Further research likely to change conclusion. + +**Very Low** (⊕○○○): Very little confidence. True effect is likely substantially different. Any estimate is very uncertain. + +--- + +## 4. Meta-Analysis Techniques + +### When to Pool (Meta-Analysis) + +**Pool when**: +- Studies address same PICO question +- Outcomes measured similarly (same construct, similar timepoints) +- Low to moderate heterogeneity (I² < 60%) +- At least 3 studies available + +**Do not pool when**: +- Substantial heterogeneity (I² > 75%) unexplained by subgroups +- Different interventions (can't pool aspirin with warfarin for "anticoagulation") +- Different populations (adults vs children, mild vs severe disease) +- Methodologically flawed studies (high risk of bias) + +### Statistical Models + +**Fixed-effect model**: Assumes one true effect, differences due to sampling error only. +- **Use when**: I² < 25%, studies very similar +- **Calculation**: Inverse-variance weighting (larger studies get more weight) + +**Random-effects model**: Assumes distribution of true effects, accounts for between-study variance. +- **Use when**: I² ≥ 25%, clinical heterogeneity expected +- **Calculation**: DerSimonian-Laird or REML methods +- **Note**: Gives more weight to smaller studies than fixed-effect + +**Recommendation**: Use random-effects as default for clinical heterogeneity, even if I² low. + +### Effect Measures + +**Binary outcomes** (event yes/no): +- **Risk Ratio (RR)**: Events in intervention / Events in control. Easier to interpret than OR. +- **Odds Ratio (OR)**: Used when outcome rare (<10%) or case-control design. +- **Risk Difference (RD)**: Absolute difference. Important for clinical interpretation (NNT = 1/RD). + +**Continuous outcomes** (measured on scale): +- **Mean Difference (MD)**: When outcome measured on same scale (e.g., mm Hg blood pressure) +- **Standardized Mean Difference (SMD)**: When outcome measured on different scales (different QoL questionnaires). Interpret as effect size: SMD 0.2 = small, 0.5 = moderate, 0.8 = large. + +**Time-to-event outcomes**: +- **Hazard Ratio (HR)**: Accounts for censoring and time. From Cox proportional hazards models. + +### Heterogeneity Assessment + +**I² statistic**: % of variability due to heterogeneity rather than chance. +- **I² = 0-25%**: Low heterogeneity (might not need subgroup analysis) +- **I² = 25-50%**: Moderate heterogeneity (explore sources) +- **I² = 50-75%**: Substantial heterogeneity (subgroup analysis essential) +- **I² > 75%**: Considerable heterogeneity (consider not pooling) + +**Cochran's Q test**: Tests whether heterogeneity is statistically significant (p<0.10 suggests heterogeneity). +- **Limitation**: Low power with few studies, high power with many studies (may detect clinically unimportant heterogeneity) + +**Exploring heterogeneity**: +1. Visual inspection (forest plot - outliers?) +2. Subgroup analysis (by population, intervention, setting, risk of bias) +3. Meta-regression (if ≥10 studies) - test whether study-level characteristics (year, dose, age) explain heterogeneity +4. Sensitivity analysis (exclude high risk of bias, exclude outliers) + +### Publication Bias Assessment + +**Methods** (require ≥10 studies): +- **Funnel plot**: Plot effect size vs precision (SE). Asymmetry suggests small-study effects/publication bias. +- **Egger's test**: Statistical test for funnel plot asymmetry (p<0.10 suggests bias). +- **Trim and fill**: Impute missing studies and recalculate pooled effect. + +**Limitations**: Asymmetry can be due to heterogeneity, not just publication bias. Small-study effects != publication bias. + +**Search mitigation**: Search clinical trial registries (ClinicalTrials.gov, EudraCT), contact authors, grey literature. + +--- + +## 5. Advanced Study Designs + +### Pragmatic Trials + +**Purpose**: Evaluate effectiveness in real-world settings (vs efficacy in ideal conditions). + +**Characteristics**: +- Broad inclusion criteria (representative of clinical practice) +- Minimal exclusions (include comorbidities, elderly, diverse populations) +- Flexible interventions (allow adaptations like clinical practice) +- Clinically relevant comparators (usual care, not placebo) +- Patient-important outcomes (mortality, QoL, not just biomarkers) +- Long-term follow-up (capture real-world adherence, adverse events) + +**PRECIS-2 wheel**: Rates trials from explanatory (ideal conditions) to pragmatic (real-world) on 9 domains. + +**Example**: HOPE-3 trial (polypill for CVD prevention) - broad inclusion, minimal monitoring, usual care comparator, long-term follow-up. + +### Non-Inferiority Trials + +**Purpose**: Show new treatment is "not worse" than standard (by pre-defined margin), usually because new treatment has other advantages (cheaper, safer, easier). + +**Key concepts**: +- **Non-inferiority margin** (Δ): Maximum acceptable difference. New treatment preserves ≥50% of standard's benefit over placebo. +- **One-sided test**: Test whether upper limit of 95% CI for difference < Δ. +- **Interpretation**: If upper CI < Δ, declare non-inferiority. If CI crosses Δ, inconclusive. + +**Pitfalls**: +- Large non-inferiority margins (>50% of benefit) allow ineffective treatments +- Per-protocol analysis bias (favors non-inferiority); need ITT + per-protocol +- Assay sensitivity: Must show historical evidence that standard > placebo + +**Example**: Enoxaparin vs unfractionated heparin for VTE treatment. Margin = 2% absolute difference in recurrent VTE. + +### Cluster Randomized Trials + +**Design**: Randomize groups (hospitals, clinics, communities) not individuals. + +**When used**: +- Intervention delivered at group level (policy, training, quality improvement) +- Contamination risk if individuals randomized (control group adopts intervention) + +**Statistical consideration**: +- **Intracluster correlation (ICC)**: Individuals within cluster more similar than across clusters +- **Design effect**: Effective sample size reduced: Deff = 1 + (m-1) × ICC, where m = cluster size +- **Analysis**: Account for clustering (GEE, mixed models, cluster-level analysis) + +**Example**: COMMIT trial (smoking cessation at workplace level). Randomized worksites, analyzed accounting for clustering. + +### N-of-1 Trials + +**Design**: Single patient receives multiple crossovers between treatments in random order. + +**When used**: +- Chronic stable conditions (asthma, arthritis, chronic pain) +- Rapid onset/offset treatments +- Substantial inter-patient variability in response +- Patient wants personalized evidence + +**Requirements**: +- ≥3 treatment periods per arm (A-B-A-B-A-B) +- Washout between periods if needed +- Blind patient and assessor if possible +- Pre-specify outcome and decision rule + +**Analysis**: Compare outcomes during A vs B periods within patient (paired t-test, meta-analysis across periods). + +**Example**: Stimulant dose optimization for ADHD. Test 3 doses + placebo in randomized crossover, 1-week periods each. + +--- + +## 6. Outcome Measurement + +### Minimal Clinically Important Difference (MCID) + +**Definition**: Smallest change in outcome that patients perceive as beneficial (and would mandate change in management). + +**Determination methods**: +1. **Anchor-based**: Link change to external anchor ("How much has your pain improved?" - "A little" threshold) +2. **Distribution-based**: 0.5 SD or 1 SE as MCID (statistical, not patient-centered) +3. **Delphi consensus**: Expert panel agrees on MCID + +**Examples**: +- **Pain VAS** (0-100): MCID = 10-15 points +- **6-minute walk distance**: MCID = 30 meters +- **KCCQ** (Kansas City Cardiomyopathy Questionnaire): MCID = 5 points +- **FEV₁** (lung function): MCID = 100-140 mL + +**Interpretation**: Effect size must exceed MCID to be clinically meaningful. p<0.05 with effect < MCID = statistically significant but clinically trivial. + +### Composite Outcomes + +**Definition**: Combines ≥2 outcomes into single endpoint (e.g., "death, MI, or stroke"). + +**Advantages**: +- Increases event rate → reduces required sample size +- Captures multiple aspects of benefit/harm + +**Disadvantages**: +- Obscures which component drives effect (mortality reduction? or non-fatal MI?) +- Components may not be equally important to patients (MI ≠ revascularization) +- If components affected differently, composite can mislead + +**Guidelines**: +- Report components separately +- Verify effect is consistent across components +- Weight components by importance if possible +- Avoid composites with many low-importance components + +**Example**: MACE (major adverse cardiac events) = death + MI + stroke (appropriate). But "death, MI, stroke, or revascularization" dilutes with less important outcome. + +### Surrogate Outcomes + +**Definition**: Biomarker/lab value used as substitute for patient-important outcome. + +**Valid surrogate criteria** (Prentice criteria): +1. Surrogate associated with clinical outcome (correlation) +2. Intervention affects surrogate +3. Intervention's effect on clinical outcome is mediated through surrogate +4. Effect on surrogate fully captures effect on clinical outcome + +**Problems**: +- Many surrogates fail criteria #4 (e.g., antiarrhythmics reduce PVCs but increase mortality) +- Intervention can affect surrogate without affecting clinical outcome + +**Examples**: +- **Good surrogate**: Blood pressure for stroke (validated, consistent) +- **Poor surrogate**: Bone density for fracture (drugs increase density but not all reduce fracture) +- **Unvalidated**: HbA1c for microvascular complications (association exists, but lowering HbA1c doesn't always reduce complications) + +**Recommendation**: Prioritize patient-important outcomes. Accept surrogates only if validated relationship exists and patient-important outcome infeasible. + +--- + +## 7. Special Populations & Contexts + +**Pediatric Evidence**: Age-appropriate outcomes (developmental milestones, parent-reported), pharmacokinetic modeling for dose prediction, extrapolation from adults if justified, expert opinion carries more weight when RCTs infeasible. + +**Rare Diseases**: N-of-1 trials, registries, historical controls (with caution), Bayesian methods to reduce sample requirements. Regulatory allows lower evidence standards (orphan drugs, conditional approval). + +**Health Technology Assessment**: Assesses clinical effectiveness (GRADE), safety, cost-effectiveness (cost per QALY), budget impact, organizational/ethical/social factors. Thresholds vary (£20-30k/QALY UK, $50-150k US). Requires systematic review + economic model + probabilistic sensitivity analysis. + +--- + +## 8. Knowledge Translation + +**Evidence-to-Decision Framework** (GRADE): Problem priority → Desirable/undesirable effects → Certainty → Values → Balance of benefits/harms → Resources → Equity → Acceptability → Feasibility. + +**Recommendation strength**: +- **Strong** ("We recommend"): Most patients would want, few would not +- **Conditional** ("We suggest"): Substantial proportion might not want, or uncertainty high + +**Guideline Development**: Scope/PICOT → Systematic review → GRADE profiles → EtD framework → Recommendation (strong vs conditional) → External review → Update plan (3-5 years). COI management critical. AGREE II assesses guideline quality. + +--- + +## 9. Common Pitfalls & Fixes + +**Surrogate outcomes**: Using unvalidated biomarkers. **Fix**: Prioritize patient-important outcomes (mortality, QoL). + +**Composite outcomes**: Obscuring which component drives effect. **Fix**: Report components separately, verify consistency. + +**Subgroup proliferation**: Data dredging for false positives. **Fix**: Pre-specify <5 subgroups, test interaction, require plausibility. + +**Statistical vs clinical significance**: p<0.05 with effect below MCID. **Fix**: Compare to MCID, report absolute effects (NNT). + +**Publication bias**: Missing null results. **Fix**: Search trial registries (ClinicalTrials.gov), contact authors, assess funnel plot. + +**Poor applicability**: Extrapolating from selected trials. **Fix**: Assess PICO match, setting differences, patient values. + +**Causation claims**: From observational data. **Fix**: Use causal language only for RCTs or strong obs evidence (large effect, dose-response). + +**Industry bias**: Uncritical acceptance. **Fix**: Assess COI, check selective reporting, verify independent analysis. diff --git a/skills/domain-research-health-science/resources/template.md b/skills/domain-research-health-science/resources/template.md new file mode 100644 index 0000000..7afc6c8 --- /dev/null +++ b/skills/domain-research-health-science/resources/template.md @@ -0,0 +1,394 @@ +# Domain Research: Health Science - Templates + +## Workflow + +``` +Health Research Progress: +- [ ] Step 1: Formulate research question (PICOT) +- [ ] Step 2: Assess evidence hierarchy and study design +- [ ] Step 3: Evaluate study quality and bias +- [ ] Step 4: Prioritize and define outcomes +- [ ] Step 5: Synthesize evidence and grade certainty +- [ ] Step 6: Create decision-ready summary +``` + +**Step 1: Formulate research question (PICOT)** + +Use [PICOT Framework](#picot-framework) to structure precise research question with Population, Intervention, Comparator, Outcome, and Timeframe fully specified. + +**Step 2: Assess evidence hierarchy and study design** + +Select appropriate study design for question type using [Common Question Types](#common-question-types) guidance (RCT for therapy, cross-sectional for diagnosis, cohort for prognosis, observational for rare harms). + +**Step 3: Evaluate study quality and bias** + +Apply bias assessment using [Evidence Appraisal Template](#evidence-appraisal-template) with appropriate tool (Cochrane RoB 2 for RCTs, ROBINS-I for observational, QUADAS-2 for diagnostic). + +**Step 4: Prioritize and define outcomes** + +Create hierarchy using [Outcome Hierarchy Template](#outcome-hierarchy-template), prioritizing patient-important outcomes (mortality, QoL) over surrogates (biomarkers), and specify MCID. + +**Step 5: Synthesize evidence and grade certainty** + +Rate certainty using [GRADE Evidence Profile Template](#grade-evidence-profile-template), assessing study limitations, inconsistency, indirectness, imprecision, and publication bias. + +**Step 6: Create decision-ready summary** + +Produce evidence summary using [Clinical Interpretation Template](#clinical-interpretation-template) with benefits/harms balance, certainty ratings, applicability, and evidence gaps identified. + +--- + +## PICOT Framework + +### Research Question Template + +**Clinical scenario**: [Describe the decision problem or knowledge gap] + +### PICOT Components + +**P (Population)**: +- **Demographics**: [Age range, sex, race/ethnicity if relevant] +- **Condition**: [Disease, severity, stage, diagnostic criteria] +- **Setting**: [Primary care, hospital, community, country/region] +- **Inclusion criteria**: [Key eligibility requirements] +- **Exclusion criteria**: [Factors that make evidence inapplicable] + +**I (Intervention)**: +- **Type**: [Drug, procedure, diagnostic test, preventive measure, exposure] +- **Specification**: [Dose, frequency, duration, route, technique details] +- **Co-interventions**: [Other treatments given alongside] +- **Timing**: [When initiated relative to disease course] + +**C (Comparator)**: +- **Type**: [Placebo, standard care, alternative treatment, no intervention] +- **Specification**: [Same level of detail as intervention] +- **Rationale**: [Why this comparator?] + +**O (Outcome)**: +- **Primary outcome**: [Most important endpoint - typically patient-important] + - Measurement instrument/definition + - Timepoint for assessment + - Minimal clinically important difference (MCID) if known +- **Secondary outcomes**: [Additional endpoints] +- **Safety outcomes**: [Harms, adverse events] + +**T (Timeframe)**: +- **Follow-up duration**: [How long?

Selective scanning creates blind spots. Weak signals often appear in unexpected domains. + +2. **Distinguish weak signals from noise**: Weak signals are early indicators with potential impact, not every random anomaly. Validate: Does source have credibility? Is there supporting evidence? Is amplification plausible? Is impact significant if it scales? Avoid signal inflation (calling everything a weak signal). + +3. **Scenarios must be plausible, not preferred or feared**: Scenarios are not predictions or wish fulfillment. They should span range of outcomes based on critical uncertainties, be internally consistent (logic holds), and challenge current assumptions. Avoid creating only optimistic scenarios or dystopian extremes. + +4. **Critical uncertainties have high impact AND high uncertainty**: Not all trends are critical uncertainties for scenario building. Use 2x2 matrix: High impact + low uncertainty = predetermined elements (plan for them). High impact + high uncertainty = critical uncertainties (build scenarios around). Low impact = context (note but don't scenario around). + +5. **Cross-impacts matter as much as individual trends**: Trends interact (AI + climate policy + geopolitics). Reinforcing trends accelerate (renewable cost decline + climate policy + corporate commitments). Offsetting trends create tension (privacy vs personalization). Cascading trends trigger others (pandemic → remote work → office demand collapse). Map interactions, don't treat trends in isolation. + +6. **Signposts must be observable and leading, not lagging**: Signposts trigger adaptation before full trend materializes. Leading indicators precede outcomes (building permits before housing prices). Lagging indicators confirm but arrive too late (GDP growth rate). Threshold must be specific (">20% market share" not "significant adoption") and monitorable (data exists, update frequency known). + +7. **Foresight informs strategy, doesn't dictate it**: Scenarios reveal possibilities and test strategy robustness, but don't automatically prescribe action. Strategy choices depend on risk appetite, resources, values. Use scenarios to stress-test plans ("does our strategy work in scenarios A, B, C?") and identify no-regrets moves (work in all scenarios) vs hedges (work in some). + +8. **Update scans regularly, not once**: Environmental conditions change. Set scanning cadence (quarterly PESTLE review, monthly weak signal scan, annual scenario update). Stale scans miss emerging trends. Rigid scenarios ignore new information. Foresight is continuous monitoring, not one-time exercise. + +**Common pitfalls:** + +- ❌ **Confirmation bias in scanning**: Only collecting evidence supporting existing beliefs. Seek disconfirming evidence, alternate views. +- ❌ **Extrapolating linearly**: Assuming current trends continue unchanged. Consider inflection points, reversals, discontinuities. +- ❌ **Treating scenarios as predictions**: Scenarios are not forecasts. No probabilities assigned (or equal probability). They explore "what if" not "what will". +- ❌ **Too many scenarios (>4)**: Overwhelming decision-makers, diluting focus. Aim for 3-4 distinct scenarios covering key uncertainties. +- ❌ **Ignoring wild cards**: Low-probability, high-impact events (pandemic, breakthrough, collapse). Acknowledge them even if not primary scenarios. +- ❌ **Anchoring to recent past**: Recency bias makes recent events (pandemic, financial crisis) loom large.

Make them visible ("Assuming 250 workdays/year", "If conversion rate ~3%"). Allows others to challenge/refine. Unstated assumptions create false precision. + +2. **Aim for order of magnitude, not precision**: Goal is 10^X, not X.XX. Round to 1-2 significant figures (50 not 47.3, 3M not 2,847,291). False precision wastes time and misleads. If decision needs precision, don't use Fermi—get real data. + +3. **Decompose until components are estimable**: Break down until you reach quantities you can estimate from knowledge/experience. If a component is still "how would I know that?", decompose further. Avoid plugging in wild guesses for complex sub-problems. + +4. **Use multiple paths (triangulation)**: Estimate same quantity via different decompositions (top-down vs bottom-up, supply-side vs demand-side). If paths agree within factor of 3, confidence increases. If they differ by 10x+, investigate which decomposition is flawed. + +5. **Bound the answer**: Calculate optimistic and pessimistic cases to bracket reality. If decision is same across range (market is $1B or $10B, either way we enter), bounds matter less. If decision flips (profitable at $10M, not at $1M), need precision or better estimate. + +6. **Sanity-check against reality**: Does answer pass smell test? Compare to known quantities (your estimate for Starbucks revenue should be within 10x of actual ~$35B). Use dimensional analysis (units should cancel correctly). Check extreme cases (what if everyone did X? does it break physics?). + +7. **Calibrate on known problems**: Practice on questions with verifiable answers (US population, Disney World attendance, wheat production). Identify your biases (overestimate? underestimate? anchoring?). Improves future estimates. + +8. **Acknowledge uncertainty ranges**: Express estimates as ranges or confidence intervals when appropriate ("10-100k users", "likely $1-5M"). Communicates epistemic humility. Avoids false precision trap. + +**Common pitfalls:** + +- ❌ **Anchoring on the wrong number**: Using irrelevant or biased starting point. If someone says "Is it 1 million?" you anchor there even if no reason to. +- ❌ **Double-counting**: Including same quantity twice in decomposition (counting both businesses and employees when businesses already includes employees). +- ❌ **Unit errors**: Mixing per-day and per-year, confusing millions and billions, wrong currency conversion. Always check units. +- ❌ **Survivor bias**: Estimating based on successful cases (average startup revenue from unicorns, not including failures). +- ❌ **Linear extrapolation**: Assuming linear growth when exponential (or vice versa). Growth rates change over time. +- ❌ **Ignoring constraints**: Physical limits (can't exceed speed of light), economic limits (market can't grow faster than GDP forever). + +## Quick Reference + +**Key

Prioritize: children, elderly, people with disabilities, marginalized/discriminated groups, low-income, low-literacy, geographically isolated, politically targeted. If none identified, you're probably missing them. + +2. **Consider second-order and long-term effects**: First-order obvious harms are just the start. Look for: feedback loops (harm → disadvantage → more harm), normalization (practice becomes standard), precedent (enables worse future behavior), accumulation (small harms compound over time). Ask "what happens next?" + +3. **Assess differential impact, not just average**: Feature may help average user but harm specific groups. Metrics: disparate impact (outcome differences across groups >20% = red flag), intersectionality (combinations of identities may face unique harms), distributive justice (who gets benefits vs. burdens?). + +4. **Design mitigations before launch, not after harm**: Reactive fixes are too late for those already harmed. Proactive: Build safeguards into design, test with diverse users, staged rollout with monitoring, kill switches, pre-commit to audits. "Move fast and break things" is unethical for systems affecting people's lives. + +5. **Provide transparency and recourse**: People affected have right to know and contest. Minimum: Explain decisions (what factors, why outcome), Appeal mechanism (human review, overturn if wrong), Redress (compensate harm), Audit trails (investigate complaints). Opacity is often a sign of hidden bias or risk. + +6. **Monitor outcomes, not just intentions**: Good intentions don't prevent harm. Measure actual impacts: outcome disparities by group, user-reported harms, error rates and their distribution, unintended consequences. Set thresholds that trigger review/shutdown. + +7. **Establish clear accountability and escalation**: Assign ownership. Define: Who reviews ethics risks before launch? Who monitors post-launch? What triggers escalation? Who can halt harmful features? Document decisions and rationale for later review. + +8. **Respect autonomy and consent**: Users deserve: Informed choice (understand what they're agreeing to, in plain language), Meaningful alternatives (consent not coerced), Control (opt out, delete data, configure settings), Purpose limitation (data used only for stated purpose). Children and vulnerable groups need extra protections. + +**Common pitfalls:** + +- ❌ **Assuming "we treat everyone the same" = fairness**: Equal treatment of unequal groups perpetuates inequality. Fairness often requires differential treatment. +- ❌ **Optimization without constraints**: Maximizing engagement/revenue unconstrained leads to amplifying outrage, addiction, polarization. Set ethical boundaries. +- ❌ **Moving fast and apologizing later**: For safety/ethics, prevention > apology. Harms to vulnerable groups are not acceptable experiments. +- ❌ **Privacy theater**: Requiring consent without explaining risks, or making consent mandatory for service, is not meaningful consent. +- ❌ **Sampling bias in testing**: Testing only on employees (young, educated, English-speaking) misses how diverse users experience harm. +- ❌ **Ethics washing**: Performative statements without material changes.

Vague criteria lead to unreliable scoring. Test: Can two independent reviewers score this criterion consistently? + +2. **Descriptors must distinguish levels clearly**: Each level should have concrete differences from adjacent levels (not just "better" or "more"). Avoid: "5=very good, 4=good, 3=okay". Better: "5=zero bugs, meets all requirements, 4=1-2 minor bugs, meets 90% requirements, 3=3+ bugs or missing key feature". + +3. **Use appropriate scale granularity**: 1-3 too coarse (hard to differentiate), 1-10 too fine (false precision, hard to define all levels). Sweet spot: 1-4 (forced choice, no middle) or 1-5 (allows neutral middle). Match granularity to actual observable differences. + +4. **Balance comprehensiveness with simplicity**: More criteria = more detailed feedback but longer to use. Aim for 4-8 criteria covering essential quality dimensions. If >10 criteria, consider grouping or prioritizing. + +5. **Calibrate for inter-rater reliability**: Have multiple reviewers score same work, measure agreement (Kappa, ICC). If <70% agreement, refine descriptors. Schedule calibration sessions where reviewers discuss discrepancies. + +6. **Provide examples at each level**: Abstract descriptors are ambiguous. Include concrete examples of work at each level (anchor papers, reference designs, code samples) to calibrate reviewers. + +7. **Make rubric accessible before evaluation**: If evaluatees see rubric only after being scored, it's just grading not guidance. Share rubric upfront so people know expectations and can self-assess. + +8. **Weight criteria appropriately**: Not all criteria equally important. If "Security" matters more than "Code style", weight it (Security ×3, Style ×1). Or use thresholds (must score ≥4 on Security to pass, regardless of other scores). + +**Common pitfalls:** + +- ❌ **Subjective language**: "Shows effort", "creative", "professional" - not observable without concrete descriptors +- ❌ **Overlapping criteria**: "Clarity" and "Organization" often conflated - define boundaries clearly +- ❌ **Hidden expectations**: Rubric doesn't mention X, but evaluators penalize for missing X - document all criteria +- ❌ **Central tendency bias**: Reviewers avoid extremes (always score 3/5) - use even-number scales (1-4) to force choice +- ❌ **Halo effect**: High score on one criterion biases other scores up - score each criterion independently before looking at others +- ❌ **Rubric drift**: Descriptors erode over time, reviewers interpret differently - periodic re-calibration required + +## Quick Reference + +**Key resources:** + +- **[resources/template.md](resources/template.md)**: Purpose definition, criteria brainstorming, scale selection, descriptor templates, rubric formats +- **[resources/methodology.md](resources/methodology.md)**: Scale design principles, descriptor writing techniques, inter-rater reliability testing, bias mitigation +- **[resources/evaluators/rubric_evaluation_rubrics.json](resources/evaluators/rubric_evaluation_rubrics.json)**: Quality criteria for rubric design (criteria clarity, scale appropriateness, descriptor specificity) + +**Scale Selection Guide**: + +| Scale | Use When | Pros | Cons | +|-------|----------|------|------| +| **1-3** | Need quick categorization, clear tiers | Fast, forces clear decision | Too coarse, less feedback | +| **1-4** | Want forced choice (no middle) | Avoids central tendency, clear differentiation | No neutral option, feels binary | +| **1-5** | General purpose, most common | Allows neutral, familiar, good granularity | Central tendency bias (everyone gets 3) | +| **1-10** | Need fine gradations, large sample | Maximum differentiation, statistical analysis | False precision, hard to distinguish adjacent levels | +| **Qualitative** (Novice/Proficient/Expert) | Educational, skill development | Intuitive, growth-oriented | Less quantitative, harder to aggregate | +| **Binary** (Yes/No, Pass/Fail) | Compliance, gatekeeping | Objective, simple | No gradations, misses quality differences | + +**Criteria Types**: + +- **Product criteria**: Evaluate the artifact itself (correctness, clarity, completeness, aesthetics, performance) +- **Process criteria**: How work was done (methodology followed, collaboration, iteration, time management) +- **Impact criteria**: Outcomes/effects (user satisfaction, business value, learning achieved) +- **Meta criteria**: Quality of quality (documentation, testability, maintainability, scalability) + +**Inter-Rater Reliability Benchmarks**: + +- **<50% agreement**: Rubric unreliable, needs major revision +- **50-70% agreement**: Marginal, refine descriptors and calibrate reviewers +- **70-85% agreement**: Good, acceptable for most uses +- **>85% agreement**: Excellent, highly reliable scoring + +**Typical Rubric Development Time**: + +- **Simple rubric** (3-5 criteria, 1-4 scale, known domain): 2-4 hours +- **Standard rubric** (5-7 criteria, 1-5 scale, some complexity): 6-10 hours + calibration session +- **Complex rubric** (8+ criteria, multiple scales, novel domain): 15-25 hours + multiple calibration rounds + +**When to escalate beyond rubrics**: + +- High-stakes decisions (hiring, admissions, awards) → Add structured interviews, portfolios, multi-method assessment +- Subjective/creative work (art, poetry, design) → Supplement rubric with critique, discourse, expert judgment +- Complex holistic judgment (leadership, cultural fit) → Rubrics help but don't capture everything, use thoughtfully +→ Rubrics are tools not replacements for human judgment.

Scale Design Principles + +### Choosing Appropriate Granularity + +**The granularity dilemma**: Too few levels (1-3) miss meaningful distinctions; too many levels (1-10) create false precision and inconsistency. + +| Factor | Favors Fewer Levels (1-3, 1-4) | Favors More Levels (1-5, 1-10) | +|--------|--------------------------------|--------------------------------| +| Evaluator expertise | Novice reviewers, unfamiliar domain | Expert reviewers, deep domain knowledge | +| Observable differences | Hard to distinguish subtle differences | Clear gradations exist | +| Stakes | High-stakes binary decisions (pass/fail) | Developmental feedback, rankings | +| Sample size | Small samples (< 20 items) | Large samples (100+, statistical analysis) | +| Time available | Quick screening, time pressure | Detailed assessment, ample time | +| Consistency priority | Inter-rater reliability critical | Differentiation more important | + +**Scale characteristics** (See SKILL.md Quick Reference for detailed comparison): +- **1-3**: Fast, coarse, high reliability. Use for quick screening. +- **1-4**: Forces choice (no middle), avoids central tendency. Use when bias observed. +- **1-5**: Most common, allows neutral, good balance. General purpose. +- **1-10**: Fine gradations, statistical analysis. Use for large samples (100+), expert reviewers. +- **Qualitative** (Novice/Proficient/Expert): Intuitive for skills, growth-oriented. Educational contexts. + +### Central Tendency and Response Biases + +**Central tendency bias**: Reviewers avoid extremes, cluster around middle (most get 3/5). + +**Causes**: Uncertainty, social pressure, lack of calibration. + +**Mitigations**: +1. **Even-number scales** (1-4, 1-6) force choice above/below standard +2. **Anchor examples** at each level (what does 1 vs 5 look like?) +3. **Calibration sessions** where reviewers score same work, discuss discrepancies +4. **Forced distributions** (controversial): Require X% in each category. Use sparingly. + +**Other response biases**: + +- **Halo effect**: Overall impression biases individual criteria scores. + - **Mitigation**: Vertical scoring (all work on Criterion 1, then Criterion 2), blind scoring. + +- **Leniency/severity bias**: Reviewer consistently scores higher/lower than others. + - **Mitigation**: Calibration sessions, normalization across reviewers. + +- **Range restriction**: Reviewer uses only part of scale (always 3-4, never 1-2 or 5). + - **Mitigation**: Anchor examples at extremes, forced distribution (cautiously). + +### Numeric vs. Qualitative Scales + +**Numeric** (1-5, 1-10): Easy to aggregate, quantitative comparison, ranking. Numbers feel precise but may be arbitrary. + +**Qualitative** (Novice/Proficient/Expert, Below/Meets/Exceeds): Intuitive labels, less false precision. Harder to aggregate, ordinal only. + +**Hybrid approach** (best of both): Numeric with labels (1=Poor, 2=Fair, 3=Adequate, 4=Good, 5=Excellent). Labels anchor meaning, numbers enable analysis. + +**Unipolar vs. Bipolar**: +- **Unipolar**: 1 (None) → 5 (Maximum). Measures amount or quality. **Use for rubrics.** +- **Bipolar**: 1 (Strongly Disagree) → 5 (Strongly Agree), 3=Neutral. Measures agreement. + +--- + +## 2. Descriptor Writing Techniques + +### Observable, Measurable Language + +**Core principle**: Two independent reviewers should score the same work consistently based on descriptors alone. + +| ❌ Subjective (Avoid) | ✓ Observable (Use) | +|----------------------|-------------------| +| "Shows effort" | "Submitted 3 drafts, incorporated 80%+ of feedback" | +| "Creative" | "Uses 2+ techniques not taught, novel combination of concepts" | +| "Professional quality" | "Zero typos, consistent formatting, APA citations correct" | +| "Good understanding" | "Correctly applies 4/5 key concepts, explains mechanisms" | +| "Needs improvement" | "Contains 5+ bugs, missing 2 required features, <100ms target" | + +**Test for observability**: Could two reviewers count/measure this? (Yes → observable). Does this require mind-reading? (Yes → subjective). + +**Techniques**: +1. **Quantification**: "All 5 requirements met" vs. "Most requirements met" +2. **Explicit features**: "Includes abstract, intro, methods, results, discussion" vs. "Complete structure" +3. **Behavioral indicators**: "Asks clarifying questions, proposes alternatives" vs. "Critical thinking" +4. **Comparison to standards**: "WCAG AA compliant" vs. "Accessible" + +### Parallel Structure Across Levels + +**Parallel structure**: Each level addresses the same aspects, making differences clear. + +**Example: Code Review, "Readability" criterion** + +| Level | Variable Names | Comments/Docs | Code Complexity | +|-------|---------------|---------------|-----------------| +| **5** | Descriptive, domain-appropriate | Comprehensive docs, all functions commented | Simple, DRY, single responsibility | +| **3** | Mostly clear, some abbreviations | Key functions documented, some comments | Moderate complexity, some duplication | +| **1** | Cryptic abbreviations, unclear | No documentation, no comments | Highly complex, nested logic, duplication | + +**Benefits**: Easy comparison (what changes 3→5?), diagnostic (pinpoint weakness), fair (same dimensions). + +### Examples and Anchors at Each Level + +**Anchor**: Concrete example of work at a specific level, calibrates reviewers. + +**Types**: +1. **Exemplar work samples**: Actual submissions scored at each level (authentic, requires permission) +2. **Synthetic examples**: Crafted to demonstrate each level (controlled, no permission needed) +3. **Annotated excerpts**: Sections highlighting what merits that score (focused, may miss holistic quality) + +**Best practices**: +- Anchor at extremes and middle (minimum: 1, 3, 5) +- Diversity of anchors (different ways to achieve a level) +- Update anchors as rubric evolves +- Make accessible to evaluators and evaluatees + +### Avoiding Hidden Expectations + +**Hidden expectation**: Quality dimension reviewers penalize but isn't in rubric. + +**Example**: Rubric has "Technical Accuracy", "Clarity", "Practical Value". Reviewer scores down for "poor visual design" (not a criterion). **Problem**: Evaluatee had no way to know design mattered. + +**Mitigation**: +1. **Comprehensive criteria**: If it matters, include it. If not in rubric, don't penalize. +2. **Criterion definitions**: Explicitly state what is/isn't included. +3. **Feedback constraints**: Suggestions outside rubric don't affect score. +4. **Rubric review**: Ask evaluatees what's missing, update accordingly. + +--- + +## 3. Calibration Techniques + +### Inter-Rater Reliability Measurement + +**Inter-rater reliability (IRR)**: Degree to which independent reviewers give consistent scores. + +**Target IRR thresholds**: +- <50%: Unreliable, major revision needed +- 50-70%: Marginal, refine descriptors, more calibration +- 70-85%: Good, acceptable for most uses +- >85%: Excellent, highly reliable + +**Measurement methods**: + +**1. Percent Agreement** +- **Calculation**: (# items where reviewers agree exactly) / (total items) +- **Pros**: Simple, intuitive. **Cons**: Inflated by chance agreement. +- **Variant: Within-1 agreement**: Scores within 1 point count as agree. Target: ≥80%. + +**2. Cohen's Kappa (κ)** +- **Calculation**: (Observed agreement - Expected by chance) / (1 - Expected by chance) +- **Range**: -1 to 1 (0=chance, 1=perfect agreement) +- **Interpretation**: <0.20 Poor, 0.21-0.40 Fair, 0.41-0.60 Moderate, 0.61-0.80 Substantial, 0.81-1.00 Almost perfect +- **Pros**: Corrects for chance. **Cons**: Only 2 raters, affected by prevalence. + +**3. Intraclass Correlation Coefficient (ICC)** +- **Use when**: More than 2 raters, continuous scores +- **Range**: 0 to 1. **Interpretation**: <0.50 Poor, 0.50-0.75 Moderate, 0.75-0.90 Good, >0.90 Excellent +- **Pros**: Handles multiple raters, gold standard. **Cons**: Requires statistical software. + +**4. Krippendorff's Alpha** +- **Use when**: Multiple raters, missing data, various data types +- **Range**: 0 to 1. **Interpretation**: α≥0.80 acceptable, ≥0.67 tentatively acceptable +- **Pros**: Most flexible, robust to missing data. **Cons**: Less familiar. + +### Calibration Session Design + +**Pre-calibration**: +1. **Select 3-5 samples** spanning quality range (low, medium, high, edge cases) +2. **Independent scoring**: Each reviewer scores all samples alone, no discussion +3. **Calculate IRR**: Baseline reliability (percent agreement, Kappa) + +**During calibration**: +4. **Discuss discrepancies** (focus on differences >1 point): "I scored Sample 1 as 4 because... What led you to 3?" +5. **Identify ambiguities**: Descriptor unclear? Criterion boundaries fuzzy? Missing cases? +6. **Refine rubric**: Clarify descriptors (add specificity, numbers, examples), add anchors, revise criteria +7. **Re-score**: Independently re-score same samples using refined rubric + +**Post-calibration**: +8. **Calculate final IRR**: If ≥70%, proceed. If <70%, iterate (more refinement + re-calibration). +9. **Document**: Date, participants, samples, IRR metrics (before/after), rubric changes, scoring decisions +10. **Schedule ongoing calibration**: Monthly or quarterly check-ins (prevents rubric drift) + +### Resolving Discrepancies + +**When reviewers disagree**: + +- **Option 1: Discussion to consensus**: Reviewers discuss, agree on final score. Ensures consistency but time-consuming. +- **Option 2: Averaged scores**: Mean of reviewers' scores. Fast but can mask disagreement (4+2=3). +- **Option 3: Third reviewer**: If A and B differ by >1, C scores as tie-breaker. Resolves impasse but requires extra reviewer. +- **Option 4: Escalation**: Discrepancies >1 escalated to lead reviewer or committee. Quality control but bottleneck. + +**Recommended**: Average for small discrepancies (1 point), discussion for large (2+ points), escalate if unresolved. + +--- + +## 4. Bias Mitigation + +### Halo Effect + +**Halo effect**: Overall impression biases individual criterion scores. "Excellent work" → all criteria high, or "poor work" → all low. + +**Example**: Code has excellent documentation (5/5) but poor performance (should be 2/5). Halo: Reviewer scores performance 4/5 due to overall positive impression. + +**Mitigation**: +1. **Vertical scoring**: Score all submissions on Criterion 1, then all on Criterion 2 (focus on one criterion at a time) +2. **Blind scoring**: Reviewers don't see previous scores when scoring new criterion +3. **Separate passes**: First pass for overall sense (don't score), second pass to score each criterion +4. **Criterion definitions**: Clear, narrow definitions reduce bleed-over + +### Anchoring and Order Effects + +**Anchoring**: First information biases subsequent judgments. First essay scored 5/5 → second (objectively 4/5) feels worse → scored 3/5. + +**Mitigation**: +1. **Randomize order**: Review in random order, not alphabetical or submission time +2. **Calibration anchors**: Review rubric and anchors before scoring (resets mental baseline) +3. **Batch scoring**: Score all on one criterion at once (easier to compare) + +**Order effects**: Position in sequence affects score (first/last reviewed scored differently). + +**Mitigation**: Multiple reviewers score in different random orders (order effect averages out). + +### Leniency and Severity Bias + +**Leniency**: Reviewer consistently scores higher than others (generous). **Severity**: Consistently scores lower (harsh). + +**Detection**: Calculate mean score per reviewer. If Reviewer A averages 4.2 and Reviewer B averages 2.8 on same work → bias present. + +**Mitigation**: +1. **Calibration sessions**: Show reviewers their bias, discuss differences +2. **Normalization** (controversial): Convert to z-scores (adjust for reviewer's mean). Changes scores, may feel unfair. +3. **Multiple reviewers**: Average scores (bias cancels out) +4. **Threshold-based**: Focus on "meets standard" (yes/no) vs numeric score + +--- + +## 5. Advanced Rubric Design + +### Weighted Criteria + +**Weighting approaches**: + +**1. Multiplicative weights**: +- Score × weight, sum weighted scores, divide by sum of weights +- Example: Security (4×3=12), Performance (3×2=6), Style (5×1=5). Total: 23/6 = 3.83 + +**2. Percentage weights**: +- Assign % to each criterion (sum to 100%) +- Example: Security 4×50%=2.0, Performance 3×30%=0.9, Style 5×20%=1.0. Total: 3.9/5.0 + +**When to weight**: Criteria have different importance, regulatory/compliance criteria, developmental priorities. + +**Cautions**: Adds complexity, can obscure deficiencies (low critical score hidden in average). Alternative: Threshold scoring. + +### Threshold Scoring + +**Threshold**: Minimum score required on specific criteria regardless of overall average. + +**Example**: +- Overall average ≥3.0 to pass +- **AND** Security ≥4.0 (critical threshold) +- **AND** No criterion <2.0 (floor threshold) + +**Benefits**: Ensures critical criteria meet standard, prevents "compensation" (high Style masking low Security), clear requirements. + +**Use cases**: Safety-critical systems, compliance requirements, competency gatekeeping. + +### Combination Rubrics + +**Hybrid approaches**: + +- **Analytic + Holistic**: Analytic for diagnostic detail, holistic for overall judgment. Use when want both. +- **Checklist + Rubric**: Checklist for must-haves (gatekeeping), rubric for quality gradations (among passing). Use for gatekeeping then ranking. +- **Self-Assessment + Peer + Instructor**: Same rubric used by student, peers, instructor. Compare scores, discuss. Use for metacognitive learning. + +--- + +## 6. Common Pitfalls + +### Overlapping Criteria + +**Problem**: Criteria not distinct, same dimension scored multiple times. + +**Example**: "Organization" (structure, flow, coherence) + "Clarity" (easy to understand, well-structured, logical). **Overlap**: "well-structured" in both. + +**Detection**: High correlation between criteria scores. Difficulty explaining difference. + +**Fix**: Define boundaries explicitly ("Organization = structure. Clarity = language."), combine overlapping criteria, or split into finer-grained distinct criteria. + +### Rubric Drift + +**Problem**: Over time, reviewers interpret descriptors differently, rubric meaning changes. + +**Causes**: No ongoing calibration, staff turnover, system changes. + +**Detection**: IRR declines (was 80%, now 60%), scores inflate/deflate (average was 3.5, now 4.2 with no quality change), inconsistency complaints. + +**Prevention**: +1. **Periodic calibration**: Quarterly sessions even with experienced reviewers +2. **Anchor examples**: Maintain library, use same anchors over time +3. **Documentation**: Record scoring decisions, accessible to new reviewers +4. **Version control**: Date rubric versions, note changes, communicate updates + +### False Precision + +**Problem**: Numeric scores imply precision that doesn't exist. 10-point scale but difference between 7 vs 8 arbitrary. + +**Fix**: +- Reduce granularity (10→5 or 3 categories) +- Add descriptors for each level +- Report confidence intervals (Score = 3.5 ± 0.5) +- Be transparent: "Scores are informed judgments, not objective measurements" + +### No Consequences for Ignoring Rubric + +**Problem**: Rubric exists but reviewers don't use it or override scores based on gut feeling. Rubric becomes meaningless. + +**Fix**: +1. **Require justification**: Reviewers must cite rubric descriptors when scoring +2. **Audit scores**: Spot-check scores against rubric, challenge unjustified deviations +3. **Training**: Emphasize rubric as contract (if wrong, change rubric, don't ignore) +4. **Accountability**: Reviewers who consistently deviate lose review privileges + +--- + +## Summary + +**Scale design**: Choose granularity matching observable differences.

Total EV = $25k. Diversified portfolio reduces risk vs. single $150k bet. + +**Pattern 3: Sequential Decision (Decision Tree)** +- **Structure**: Series of decisions over time, outcomes of early decisions affect later options +- **Use case**: Clinical trials (Phase I → II → III), staged investment, explore then exploit +- **Pros**: Captures optionality (can stop if early results bad), fold-back induction finds optimal strategy +- **Cons**: Tree grows exponentially, need probabilities for all branches +- **Example**: Phase I drug trial (70% pass, $1M cost) → if pass, Phase II (50% pass, $5M) → if pass, Phase III (40% approve, $50M revenue). Calculate EV working backwards. + +**Pattern 4: Continuous Distribution (Monte Carlo)** +- **Structure**: Outcomes are continuous (revenue could be $0-$1M), use probability distributions +- **Use case**: Financial modeling, project timelines, resource planning, sensitivity analysis +- **Pros**: Captures full uncertainty, avoids discrete scenario bias, provides confidence intervals +- **Cons**: Requires distributional assumptions, computationally intensive, harder to communicate +- **Example**: Revenue ~ Normal($500k, $100k std dev). Run 10,000 simulations → mean = $510k, 90% CI = [$350k, $670k]. + +**Pattern 5: Competitive Game (Payoff Matrix)** +- **Structure**: Your outcome depends on competitor's choice, create payoff matrix +- **Use case**: Pricing strategy, product launch timing, negotiation, auction bidding +- **Pros**: Incorporates strategic interaction, finds Nash equilibrium +- **Cons**: Requires estimating competitor's probabilities and payoffs, game-theoretic complexity +- **Example**: Price high vs. low, competitor prices high vs. low → 2×2 matrix. Calculate EV for each strategy given beliefs about competitor. + +## Guardrails + +**Critical requirements:** + +1. **Probabilities must sum to 1.0**: If you list outcomes, their probabilities must be exhaustive (cover all possibilities) and mutually exclusive (no overlap). Check: p₁ + p₂ + ... + pₙ = 1.0. + +2. **Don't use EV for one-shot, high-stakes decisions without risk adjustment**: EV is long-run average. For rare, irreversible decisions (bet life savings, critical surgery), consider risk aversion. A 1% chance of $1B (EV = $10M) doesn't mean you should bet your house. + +3. **Quantify uncertainty, don't hide it**: Probabilities and payoffs are estimates, often uncertain. Use ranges (optimistic/pessimistic), sensitivity analysis, or distributions. Don't pretend false precision. + +4. **Consider non-monetary value**: EV in dollars is convenient, but some outcomes have utility not captured by money (reputation, learning, optionality, morale). Convert to common scale or use multi-attribute utility. + +5. **Probabilities must be calibrated**: Don't use gut-feel probabilities without grounding. Use base rates, reference classes, data, expert forecasts. Test: are your "70% confident" predictions right 70% of the time? + +6. **Account for correlated outcomes**: If outcomes aren't independent (economic downturn affects all portfolio companies), correlation reduces diversification benefit. Model dependencies. + +7. **Time value of money**: Payoffs at different times aren't equivalent. Discount future cash flows to present value (NPV = Σ CF_t / (1+r)^t). EV should use NPV, not nominal values. + +8. **Stopping rules and option value**: In sequential decisions, fold-back induction finds optimal strategy. Don't ignore option to stop early, pivot, or wait for more information. + +**Common pitfalls:** + +- ❌ **Ignoring risk aversion**: EV($100k, 50/50) = EV($50k, certain) but most prefer certain $50k. Use utility functions for risk-averse agents. +- ❌ **Anchor on single scenario**: "Best case is $1M!" → but probability is 5%. Focus on EV, not cherry-picked scenarios. +- ❌ **False precision**: "Probability = 67.3%" when you're guessing. Use ranges, express uncertainty. +- ❌ **Sunk cost fallacy**: Past costs are sunk, don't include in forward-looking EV. Only future costs/benefits matter. +- ❌ **Ignoring tail risk**: Low-probability, high-impact events (0.1% chance of -$10M) can dominate EV. Don't round to zero. +- ❌ **Static analysis**: Assume you can't update beliefs or change course. Real decisions allow learning and pivoting. + +## Quick Reference + +**Key formulas:** + +**Expected Value**: EV = Σ (pᵢ × vᵢ) where p = probability, v = value + +**Expected Utility** (for risk aversion): EU = Σ (pᵢ × U(vᵢ)) where U = utility function +- Risk-neutral: U(x) = x (EV = EU) +- Risk-averse: U(x) = √x or U(x) = log(x) (concave) +- Risk-seeking: U(x) = x² (convex) + +**Net Present Value**: NPV = Σ (CF_t / (1+r)^t) where CF = cash flow, r = discount rate, t = time period + +**Variance** (risk measure): Var = Σ (pᵢ × (vᵢ - EV)²) + +**Standard Deviation**: σ = √Var + +**Coefficient of Variation** (risk/return ratio): CV = σ / EV (lower = better risk-adjusted return) + +**Breakeven probability**: p* where EV = 0.

Probability Estimation Techniques + +### Base Rates (Outside View) + +**Principle**: Use historical frequency from similar situations (reference class forecasting). + +**Process**: +1. **Identify reference class**: What category of events does this belong to? (e.g., "tech startup launches", "enterprise software migrations", "clinical trials for this disease") +2. **Gather data**: How many cases in the reference class? How many succeeded vs. failed? +3. **Calculate base rate**: p(success) = # successes / # total cases +4. **Adjust for differences**: Is your case typical or atypical for the reference class? (Use inside view to adjust, but anchor on base rate.) + +**Example**: Startup success rate. Reference class = "SaaS B2B startups, 2015-2020". Data: 10,000 launches, 1,500 reached $1M ARR. Base rate = 15%. Your startup: Similar profile → start with 15%, then adjust for unique factors. + +**Cautions**: Reference class selection matters. Too broad (all startups) misses nuance. Too narrow (exactly like us) has no data. + +### Inside View (Causal Decomposition) + +**Principle**: Break outcome into necessary conditions, estimate probability of each, combine. + +**Process**: +1. **Causal chain**: What needs to happen for this outcome? (A and B and C...) +2. **Estimate each link**: What's p(A)? p(B|A)? p(C|A,B)? +3. **Combine**: If independent: p(Outcome) = p(A) × p(B) × p(C). If conditional: p(Outcome) = p(A) × p(B|A) × p(C|A,B). + +**Example**: Product launch success requires: (1) feature ships on time (80%), (2) marketing campaign reaches target audience (70%), (3) product-market fit (50%). If independent: p(success) = 0.8 × 0.7 × 0.5 = 28%. If dependent (late ship → poor marketing → worse fit): adjust. + +**Cautions**: Overconfidence in ability to model all links. Conjunction fallacy (underestimate how probabilities multiply, 80% × 80% × 80% = 51%). + +### Expert Judgment Aggregation + +**Methods**: +- **Simple average**: Mean of expert estimates. Works well if experts are independent and equally calibrated. +- **Weighted average**: Weight experts by track record (past calibration score). More weight to well-calibrated forecasters. +- **Median**: Robust to outliers. Use if some experts give extreme estimates. +- **Delphi method**: Multiple rounds. Experts see others' estimates (anonymized), revise their own, converge. + +**Calibration scoring**: Expert says "70% confident" → are they right 70% of the time? Track record via Brier score = Σ (p_i - outcome_i)² / N. Lower = better. + +**Cautions**: Group-think if experts see each other's estimates before forming own. Anchoring on first estimate heard. + +### Data-Driven Models + +**Regression**: Predict outcome probability from features. Logistic regression for binary (success/fail). Linear for continuous (revenue). + +**Time series**: If outcome is repeating event (monthly sales, weekly sign-ups), use time series (ARIMA, exponential smoothing) to forecast. + +**Machine learning**: If rich data, use ML (random forest, gradient boosting, neural nets). Provides predicted probability + confidence intervals. + +**Backtesting**: Test model on historical data. What would model have predicted vs. actual outcomes? Calibration plot: predicted 70% → actually 70%? + +**Cautions**: Overfitting (model fits noise, not signal). Out-of-distribution (future may differ from past). Need enough data (small N → high variance). + +### Combining Methods (Triangulation) + +**Best practice**: Don't rely on single method. Estimate probability using 2-4 methods, compare. + +- If estimates converge (all ~60%) → confidence high. +- If estimates diverge (base rate = 20%, inside view = 60%) → investigate why. Which assumptions differ? Truth likely in between. + +**Weighted combination**: Base rate (50% weight), Inside view (30%), Expert judgment (20%) → final estimate. + +**Update with new info**: Start with base rate (prior), update with inside view / expert / data (evidence) using Bayes theorem: p(A|B) = p(B|A) × p(A) / p(B). + +--- + +## 2. Payoff Quantification + +### Monetary Valuation + +**Direct cash flows**: Revenue, costs, savings. Straightforward to quantify. + +**Opportunity cost**: What are you giving up? (Time, resources, alternative investments). Cost = value of best alternative foregone. + +**Option value**: Does this create future options? (Pilot project → if successful, can scale. Value of option > value of pilot alone.) Use real options analysis or decision tree. + +**Time value of money**: $1 today ≠ $1 next year. Discount future cash flows to present value. + +**NPV formula**: NPV = Σ (CF_t / (1+r)^t) where CF_t = cash flow in period t, r = discount rate (WACC, hurdle rate, or risk-free + risk premium). + +**Discount rate selection**: +- Risk-free rate (US Treasury): ~3-5% +- Corporate projects: WACC (weighted average cost of capital), typically 7-12% +- Venture / high-risk: 20-40% +- Personal decisions: Opportunity cost of capital (what else could you invest in?) + +**Inflation**: Use real cash flows (inflation-adjusted) or nominal cash flows with nominal discount rate. Don't mix. + +### Non-Monetary Valuation + +**Time**: Convert to dollars. Your hourly rate (salary / hours or freelance rate). Time saved = hours × rate. Or use opportunity cost (what else could you do with time?). + +**Reputation / brand**: Harder to quantify. Approaches: +- Proxy: How much would you pay to prevent reputation damage? (e.g., PR crisis costs $X to fix → value of avoiding = $X) +- Customer lifetime value: Better reputation → higher retention → $Y in CLV +- Premium pricing: Strong brand → can charge Z% more → $W in extra revenue + +**Learning / optionality**: Value of information or skills gained. Enables future opportunities. Hard to quantify exactly, but can bound: +- Conservative: $0 (ignore) +- Optimistic: Value of best future opportunity enabled × probability you pursue it +- Expected: Sum of option values across multiple future paths + +**Strategic**: Competitive advantage, market position. Quantify via: +- Market share ×Average profit per point of share +- Defensive: How much would competitor pay to block this move? +- Offensive: How much extra profit from improved position? + +**Utility**: Some outcomes have intrinsic value not captured by money (autonomy, impact, meaning). Use utility functions or qualitative scoring (1-10 scale). + +### Handling Uncertainty in Payoffs + +**Point estimate**: Single number (expected case). Simple but hides uncertainty. + +**Range**: Optimistic / base / pessimistic (three-point estimate). Captures uncertainty. Can convert to distribution (triangular or PERT). + +**Distribution**: Full probability distribution over payoffs (normal, lognormal, beta). Most accurate but requires assumptions. Use Monte Carlo simulation. + +**Sensitivity analysis**: How much does EV change if payoff varies ±20%? Identifies which payoffs matter most. + +--- + +## 3. Decision Tree Analysis + +### Building Decision Trees + +**Nodes**: +- **Decision node** (square): You make a choice. Branches = alternatives. +- **Chance node** (circle): Uncertain event. Branches = possible outcomes with probabilities. +- **Terminal node** (triangle): End of path. Payoff specified. + +**Structure**: +- Start at left (initial decision), move right through chance and decision nodes, end at right (payoffs). +- Label all branches (decision choices, outcome names, probabilities). +- Assign payoffs to terminal nodes. + +**Conventions**: +- Probabilities on branches from chance nodes must sum to 1.0. +- Decision branches have no probabilities (you control which to take). + +### Fold-Back Induction (Solving Trees) + +**Algorithm**: Work backwards from terminal nodes to find optimal strategy. + +1. **At terminal nodes**: Payoff given. +2. **At chance nodes**: EV = Σ (p_i × payoff_i). Replace node with EV. +3. **At decision nodes**: Choose branch with highest EV. Replace node with max EV, note optimal choice. +4. **Repeat** until you reach initial decision node. + +**Result**: Optimal strategy (which choices to make at each decision node) and overall EV of following that strategy. + +**Example**: +``` +Decision 1: [Invest $100k or Don't] + If Invest → Chance: [Success 60% → $300k, Fail 40% → $0] + EV(Invest) = 0.6 × $300k + 0.4 × $0 = $180k. Net = $180k - $100k = $80k. + If Don't → $0 + Optimal: Invest (EV = $80k > $0) +``` + +### Value of Information + +**Perfect information**: If you could learn outcome of uncertain event before deciding, how much would that be worth? + +**EVPI** (Expected Value of Perfect Information): +- **With perfect info**: Choose optimal decision for each outcome. EV = Σ (p_i × best_payoff_i). +- **Without info**: EV of optimal strategy under uncertainty. +- **EVPI** = EV(with info) - EV(without info). + +**Interpretation**: Maximum you'd pay to eliminate uncertainty. If actual cost of info < EVPI, worth buying (run experiment, hire consultant, do research). + +**Partial information**: If info is imperfect (e.g., test with 80% accuracy), use Bayes theorem to update probabilities, calculate EV with updated beliefs, subtract cost of test. + +### Sequential vs. Simultaneous Decisions + +**Sequential**: Make choice, observe outcome, make next choice. Fold-back induction finds optimal strategy. Captures optionality (can stop, pivot, wait). + +**Simultaneous**: Make all choices upfront, then outcomes resolve. Less flexible but sometimes unavoidable (commit to strategy before seeing results). + +**Design for learning**: Structure decisions sequentially when possible (pilot before full launch, Phase I/II/III trials, MVP before scale). Preserves options, reduces downside. + +--- + +## 4. Risk Preferences and Utility + +### Risk Neutrality vs. Risk Aversion + +**Risk-neutral**: Only care about EV, not variance. EV($100k, 50/50) = EV($50k, certain) → indifferent. + +**Risk-averse**: Prefer certainty, willing to sacrifice EV to reduce variance. Prefer $50k certain over $100k gamble even though EV equal. + +**Risk-seeking**: Enjoy uncertainty, prefer high-variance gambles. Rare for most people/organizations. + +**When does risk matter?** +- **One-shot, high-stakes**: Can't afford to lose (bet life savings, critical product launch). Risk aversion matters. +- **Repeated, portfolio**: Many independent bets, law of large numbers. EV dominates (VCs, insurance companies, diversified portfolios). + +### Utility Functions + +**Utility** U(x): Subjective value of outcome x. For risk-averse agents, U is concave (diminishing marginal utility). + +**Common functions**: +- **Linear**: U(x) = x. Risk-neutral (EU = EV). +- **Square root**: U(x) = √x. Moderate risk aversion. +- **Logarithmic**: U(x) = log(x). Strong risk aversion (common in economics). +- **Exponential**: U(x) = -e^(-ax). Constant absolute risk aversion (CARA), parameter a = risk aversion coefficient. + +**Expected Utility**: EU = Σ (p_i × U(v_i)). Choose option with highest EU. + +**Certainty Equivalent** (CE): The guaranteed amount you'd accept instead of the gamble. Solve: U(CE) = EU. For risk-averse agents, CE < EV. + +**Risk Premium**: RP = EV - CE. How much you'd pay to eliminate risk. + +**Example**: Gamble: 50% $100k, 50% $0. EV = $50k. +- If U(x) = √x, then EU = 0.5 × √100k + 0.5 × √0 = 0.5 × 316.2 = 158.1. +- CE: √CE = 158.1 → CE = 158.1² = $25k. +- RP = $50k - $25k = $25k. Would pay up to $25k to avoid gamble, take guaranteed $50k instead. + +### Calibrating Your Utility Function + +**Questions to reveal risk aversion**: +1. "Gamble: 50% $100k, 50% $0 vs. Certain $40k. Which?" → If prefer certain $40k, you're risk-averse (CE < $50k). +2. "Gamble: 50% $200k, 50% $0 vs. Certain $X. At what X are you indifferent?" → X = CE for this gamble. +3. Repeat for several gambles, fit utility curve to your choices. + +**Organization risk tolerance**: Depends on reserves, ability to absorb loss, stakeholder expectations (public company vs. startup founder). Quantify via "How much can we afford to lose?" and "What's minimum acceptable return?" + +### Non-Linear Utility (Prospect Theory) + +**Observations** (Kahneman & Tversky): +- **Loss aversion**: Losses hurt more than equivalent gains feel good. U(loss) < -U(gain) in absolute terms. Ratio ~2:1 (losing $100 feels 2× worse than gaining $100). +- **Reference dependence**: Utility depends on change from reference point (status quo), not absolute wealth. +- **Probability weighting**: Overweight small probabilities (1% feels > 1%), underweight large probabilities (99% feels < 99%). + +**Implications**: People are risk-averse for gains, risk-seeking for losses (gamble to avoid sure loss). Framing matters (80% success vs. 20% failure). + +**Practical**: If stakeholders are loss-averse, emphasize downside protection (hedges, insurance, diversification) even if it reduces EV. + +--- + +## 5. Common Biases and Pitfalls + +### Overconfidence + +**Problem**: Estimated probabilities too extreme (80% when should be 60%). Underestimate uncertainty. + +**Detection**: Track calibration. Are your "70% confident" predictions right 70% of the time? Most people are overconfident (right 60% when say 70%). + +**Fix**: Widen probability ranges. Use reference classes (base rates). Ask "How often am I this confident and wrong?" + +### Anchoring + +**Problem**: First number you hear (or think of) biases estimate. Adjust insufficiently from anchor. + +**Example**: "Is revenue > $500k?" → even if you say no, your estimate will be anchored near $500k. + +**Fix**: Generate estimate independently before seeing anchors. Use multiple methods to triangulate (outside view, inside view, experts). + +### Availability Bias + +**Problem**: Overweight recent or vivid events. "Startup X just failed, so all startups fail" (ignoring base rate of thousands of startups). + +**Fix**: Use data / base rates, not anecdotes. Ask "How representative is this example?" + +### Sunk Cost Fallacy + +**Problem**: Include past costs in forward-looking EV. "We've already spent $1M, can't stop now!" + +**Fix**: Sunk costs are sunk. Only future costs/benefits matter. EV = future payoff - future cost. Ignore past. + +### Neglecting Tail Risk + +**Problem**: Round low-probability, high-impact events to zero. "0.1% chance of -$10M? I'll call it 0%." + +**Fix**: Don't ignore tail risk. 0.1% × -$10M = -$10k in EV (material). Sensitivity: What if probability is 1%? + +### False Precision + +**Problem**: "Probability = 67.3%, payoff = $187,432.17" when you're guessing. + +**Fix**: Express uncertainty. Use ranges (55-75%, $150k-$200k). Don't pretend more precision than you have. + +### Static Analysis (Ignoring Optionality) + +**Problem**: Assume you make all decisions upfront, can't update or pivot. Misses value of learning. + +**Fix**: Use decision trees for sequential decisions. Model optionality (stop early, wait for info, pivot). Often shifts optimal strategy. + +--- + +## 6. Advanced Topics + +### Correlation and Diversification + +**Independent outcomes**: If portfolio of uncorrelated bets, variance decreases with N (Var_portfolio = Var_single / N). Diversification works. + +**Correlated outcomes**: If outcomes move together (economic downturn hurts all investments), correlation reduces diversification benefit. Model dependencies (correlation coefficient, copulas). + +**Portfolio EV**: Sum of individual EVs (always true). Portfolio variance: More complex, depends on correlations. + +### Monte Carlo Simulation + +**When to use**: Continuous distributions, many uncertain variables, complex interactions. + +**Process**: +1. Define distributions for each uncertain variable (normal, lognormal, beta, etc.). +2. Sample randomly from each distribution (draw one value per variable). +3. Calculate outcome (payoff) for that sample. +4. Repeat 10,000+ times. +5. Analyze results: Mean = EV, percentiles = confidence intervals (5th-95th), plot histogram. + +**Pros**: Captures full uncertainty, no need for discrete scenarios, provides distribution of outcomes. + +**Cons**: Requires distributional assumptions (which may be wrong), computationally intensive, harder to communicate. + +**Tools**: Excel (@RISK, Crystal Ball), Python (NumPy, SciPy), R (mc2d). + +### Multi-Attribute Utility + +**When**: Multiple objectives (profit, risk, strategic value, ethics) that can't all be converted to dollars. + +**Approaches**: +- **Weighted scoring**: Score each option on each attribute (1-10), multiply by weight, sum. Choose highest total. +- **Utility surface**: Define utility over multiple dimensions U(x, y, z) where x=profit, y=risk, z=strategy. +- **Pareto frontier**: Identify non-dominated options (no option strictly better on all dimensions). Choose from frontier based on preferences. + +**Example**: Investment A (high profit, high risk, low strategic value), Investment B (medium profit, medium risk, high strategic value). Can't say one is objectively better. Depends on weights. + +### Game Theory (Strategic Interactions) + +**When**: Outcome depends on competitor's choice (pricing, product launch, negotiation). + +**Payoff matrix**: Rows = your choices, columns = competitor's choices, cells = your payoff given both choices. + +**Nash equilibrium**: Strategy pair where neither player wants to deviate given other's strategy. May not maximize joint value. + +**Expected value in games**: Estimate opponent's probabilities (mixed strategy or beliefs about their choice), calculate EV for each of your strategies, choose best response. + +**Cautions**: Assumes rational opponent. Real opponents may be irrational, vindictive, or making mistakes. Model their actual behavior, not ideal. + +--- + +## Summary + +**Probability estimation**: Use multiple methods (base rates, inside view, experts, data), triangulate. Avoid overconfidence, anchoring, availability bias. + +**Payoff quantification**: Include monetary (revenue, costs, NPV) and non-monetary (time, reputation, learning, strategic). Handle uncertainty with ranges or distributions. + +**Decision trees**: Fold-back induction for sequential decisions. Calculate EVPI for value of information. Structure for learning (sequential > simultaneous). + +**Risk preferences**: Risk-neutral → maximize EV. Risk-averse → maximize expected utility (EU). Calibrate utility function via elicitation. Account for loss aversion (Prospect Theory). + +**Biases**: Overconfidence, anchoring, availability, sunk cost, tail risk neglect, false precision, static analysis. Mitigate via calibration, base rates, ranges, optionality. + +**Advanced**: Correlation in portfolios, Monte Carlo for continuous distributions, multi-attribute utility for multiple objectives, game theory for strategic interactions. + +**Final principle**: EV analysis structures thinking, not mechanizes decisions. Probabilities and payoffs are estimates. Sensitivity analysis reveals robustness. Combine quantitative EV with qualitative judgment (strategic fit, alignment with values, regret minimization). diff --git a/skills/expected-value/resources/template.md b/skills/expected-value/resources/template.md new file mode 100644 index 0000000..ecee882 --- /dev/null +++ b/skills/expected-value/resources/template.md @@ -0,0 +1,338 @@ +# Expected Value Templates + +Quick-start templates for decision framing, outcome identification, probability estimation, payoff quantification, EV calculation, and sensitivity analysis. + +## Workflow + +``` +Expected Value Analysis Progress: +- [ ] Step 1: Define decision and alternatives +- [ ] Step 2: Identify possible outcomes +- [ ] Step 3: Estimate probabilities +- [ ] Step 4: Estimate payoffs (values) +- [ ] Step 5: Calculate expected values +- [ ] Step 6: Interpret and adjust for risk preferences +``` + +**Step 1: Define decision and alternatives** → Use [Decision Framing Template](#decision-framing-template) + +**Step 2: Identify possible outcomes** → Use [Outcome Identification Template](#outcome-identification-template) + +**Step 3: Estimate probabilities** → Use [Probability Estimation Template](#probability-estimation-template) + +**Step 4: Estimate payoffs** → Use [Payoff Quantification Template](#payoff-quantification-template) + +**Step 5: Calculate expected values** → Use [EV Calculation Template](#ev-calculation-template) + +**Step 6: Interpret and adjust for risk** → Use [Risk Adjustment Template](#risk-adjustment-template) and [Sensitivity Analysis Template](#sensitivity-analysis-template) + +--- + +## Decision Framing Template + +**Decision to be made**: [Clear statement of the choice] + +**Context**: [Why are you making this decision?

Format serves objective. If objective unclear, session will drift. + +2. **Time-box ruthlessly**: Parkinson's Law (work expands to fill time). Set strict timers, end activities even if incomplete. 25 min generates better focus than open-ended "until we're done." + +3. **Separate divergence from convergence**: Don't critique ideas during brainstorm (kills creativity). Defer judgment. Generate first, evaluate second. Premature convergence yields safe, obvious ideas. + +4. **Ensure psychological safety**: Ground rules (no interrupting, critique ideas not people, Vegas rule if needed). Address power dynamics (boss speaks last, use anonymous input). Without safety, you get groupthink or silence. + +5. **Manage participation actively**: Silent people have ideas (use individual writing, round robin, small groups). Verbose people dominate (time limits, "let's hear from others", parking lot for tangents). Don't let dysfunction fester. + +6. **Decide how decisions are made**: Consensus (everyone agrees), consent (no objections), majority vote, delegation (input → decision-maker). Announce method upfront. Lack of clarity → "I thought we decided, but nothing happened." + +7. **Track outputs visibly**: Shared board, live doc, sticky notes. Everyone sees same thing (reduces misunderstanding). Assign scribe if needed. Invisible outputs are easily lost. + +8. **Close with clarity**: What was decided? Who does what by when? What's still open? How will we communicate? 5 min close prevents week of confusion. + +**Common pitfalls:** + +- ❌ **No agenda**: Meetings drift, go long, participants unclear on purpose. Always have agenda (even 3 bullets). +- ❌ **Wrong people**: Decision-makers absent, too many observers, missing key stakeholders. Right people > right process. +- ❌ **Too much content**: 10 topics in 60 min = shallow on all. Better: 2-3 topics, go deep, make progress. +- ❌ **Facilitator dominates**: Facilitator should guide process, not content. Reduce own talking, ask questions, stay neutral. +- ❌ **No breaks**: 2+ hours without break → diminishing returns.

Frame the problem (narrow focus) +2. Individual brainstorm (diverge - many ideas) +3. Cluster ideas, discuss themes (converge - patterns emerge) +4. Dot vote on top ideas (decide - commit to 3-5) +``` + +**Why it works**: Diverge prevents premature convergence (jumping to first idea). Converge prevents paralysis (too many options). Structure creates productive tension. + +### Time-Boxing Principles + +**Parkinson's Law**: Work expands to fill available time. Tight time-boxes → focus. + +**Guidelines**: +- **5-10 min**: Quick individual task (write ideas, read doc) +- **15-20 min**: Small group discussion or activity +- **25-30 min**: Deep discussion or complex activity (max before energy drops) +- **45-60 min**: Absolute max without break (diminishing returns after) +- **10-15% buffer**: Add slack for overruns (60 min session → schedule 70 min) + +**Time warnings**: Give "5 minutes left" and "2 minutes, wrap up" warnings. Keeps people aware. + +**Cutting activities**: If running over, don't extend (trains bad behavior). Either ruthlessly cut remaining topics or schedule follow-up. + +### Energy Arc + +**Energy curve**: High at start (fresh), dips mid-session (fatigue), can lift at end (urgency). + +**Design for energy**: +- **Start with easy win**: Quick activity to build momentum (not heavy content immediately) +- **Hard thinking mid-session**: Complex discussion or decision when energy still good (not at end) +- **Vary modalities**: Alternate sitting/standing, individual/group, talking/silent, consuming/creating +- **Breaks**: Every 60-90 min (5-10 min).

Leads to groupthink or missing perspectives. + +**Techniques**: + +**Round Robin**: Each person speaks in turn (30 sec - 2 min each). Can't interrupt or pass. +- **Use when**: Want to hear from everyone, equal airtime important +- **Variation**: Popcorn (people nominate next speaker, ensures network spreads) + +**1-2-4-All**: Individual (1 min think alone) → Pairs (2 min discuss) → Fours (4 min synthesize) → All (report themes) +- **Use when**: Complex question, want deep thinking before sharing +- **Benefit**: Introverts process privately first, extroverts get multiple discussion rounds + +**Silent Writing / Brain-writing**: Everyone writes ideas on sticky notes or shared doc (5-10 min), no talking +- **Use when**: Brainstorming, want to avoid groupthink +- **Benefit**: Parallel idea generation (10 people generate 50 ideas in 5 min vs 30 min talking) + +**Breakout Rooms** (physical or virtual): Small groups (3-5 people) discuss, then report back +- **Use when**: >10 people, need deeper discussion than whole-group allows +- **Tip**: Give clear prompt and time limit (15-20 min). Visit rooms to check progress. + +**Anonymous Input**: Use tools (Slido, Mentimeter, shared doc) for questions or ideas without names +- **Use when**: Sensitive topics, power dynamics (boss in room), psychological safety low + +**Equalize speaking time**: Set explicit time limits (2 min per person), use timer, enforce gently +- **Tip**: "I'm going to ask everyone to keep responses to 2 minutes so we hear from all." + +### Managing Time + +**Visible timer**: Shared screen timer or physical clock. Everyone sees time remaining. + +**Time-keeper role**: Delegate to someone (not facilitator) to give warnings ("5 min left", "time") + +**Ruthless cutting**: If activity runs over, don't extend (trains people to respect time-box). Either cut remaining topics or defer to follow-up. + +**Buffer in agenda**: Add 10-15% slack. If 5 activities × 10 min each = 50 min, schedule 60 min. + +### Capturing Outputs + +**Visible board**: Everyone sees same thing (whiteboard, Mural, shared doc projected). Reduces misunderstanding. + +**Scribe role**: Delegate note-taking to someone (not facilitator). Facilitator focuses on process. + +**Structured capture**: +- Decisions: What was decided, rationale, who, when +- Action items: Specific, owner, due date +- Parking lot: Topics for later (important but off-agenda) +- Key insights: Themes, patterns, surprising learnings + +**Post-session**: Share notes within 24 hours. Faster = better (while fresh). + +--- + +## 4. Handling Difficult Dynamics + +### Dominating Participants + +**Symptoms**: Same 2-3 people talking entire time, others silent, depth of contribution varies. + +**Interventions**: +- **Round robin**: Force equal airtime +- **Direct invite**: "We haven't heard from [name] yet. What's your take?" +- **Interrupt gently**: "Thanks [name], let me pause you there and hear from others first." +- **Set ground rules upfront**: "Step up, step back" (if you talk a lot, make space; if quiet, push to contribute) +- **Private chat** (if recurring): "I appreciate your input. Can you help me by holding space for quieter folks?" + +### Silent Participants + +**Causes**: Introverted, processing time needed, intimidated, disagree but don't want conflict, multitasking. + +**Interventions**: +- **Silent writing first**: Gives time to think before talking +- **Pairs before whole group**: Safer to talk to one person first +- **Direct invite (gently)**: "We haven't heard from you, [name]. What do you think?" (Don't force if they decline) +- **Chat box / anonymous**: Can type thoughts if uncomfortable speaking +- **Offline**: "I noticed you were quiet. Any thoughts you didn't get to share?" + +**Don't assume**: Silence doesn't always mean disengagement. Some process internally. + +### Conflict or Disagreement + +**Normal and healthy** (if managed well). Different perspectives → better decisions. + +**Interventions**: +- **Surface it**: "I hear two different views. Let's understand each fully before deciding." +- **Steelman each position**: Ask each person to restate other's view ("What's the strongest argument for their position?") +- **Clarify trade-offs**: "What are we optimizing for? What do we gain/lose with each option?" +- **Separate people from ideas**: "We're debating the idea, not attacking each other." +- **Decision method clarity**: "Here's how we'll decide after hearing all views: [vote, consensus, advisory]." +- **Escalate if needed**: "We're stuck. Let's take to [decision-maker] with both views and recommendation." + +**Avoid**: Rushing to resolution, dismissing minority view, facilitator taking side. + +### Tangents or Off-Topic + +**Symptoms**: Discussion drifts from agenda, pursuing interesting but irrelevant thread. + +**Interventions**: +- **Parking lot**: "That's important, but off today's agenda. I'll capture it here and we'll address later." +- **Refocus**: "Let's come back to the question: [restate agenda item]." +- **Check with group**: "This is interesting but not on agenda. Do we want to spend time on this or stay focused?" (Usually folks choose focus) + +**Prevention**: Clear agenda upfront, ground rules about staying on-topic, strong facilitator. + +### Low Energy or Disengagement + +**Symptoms**: Laptops open, sidebar conversations, people leaving room, glazed looks. + +**Interventions**: +- **Break**: "Let's take 5 min. I see energy dropping." +- **Energizer**: Quick physical activity (stand, stretch, music, game) +- **Change format**: Switch from presentation to discussion, or whole-group to breakouts +- **Check in**: "I'm sensing low energy. What's going on? Do we need to adjust?" +- **Stop early**: If session isn't working, better to cut short than push through. "This isn't landing. Let's regroup." + +**Prevention**: Vary activities (don't lecture for 90 min), breaks every 60-90 min, start strong. + +### Power Dynamics + +**Symptoms**: Boss in room → people defer, don't speak candidly. New person → intimidated. Hierarchy suppresses dissent. + +**Interventions**: +- **Boss speaks last**: Explicitly ask senior person to hold input until others share +- **Anonymous input**: Use tools so contributions not attributed +- **Small groups**: Mix hierarchy levels, or group by level (peers discuss first) +- **Ground rules**: "Challenge ideas, not people" + "No rank in this room for next 90 min" +- **Private channels**: 1:1s for sensitive topics hierarchy prevents + +**Facilitator neutrality**: Don't align with boss or senior person. Protect space for dissent. + +--- + +## 5. Decision-Making Methods + +### Consensus + +**Definition**: Everyone must agree (or at least accept) the decision. + +**Process**: Discuss until all objections resolved. Ask "Can you live with this?" (not "Do you love it?") + +**Pros**: High buy-in, all voices heard, surfaces concerns early + +**Cons**: Slow (can take hours or multiple sessions), one person can block, pressure to conform + +**Use when**: High-stakes, irreversible decisions. Team needs to deeply own outcome. Time available. + +**Red flags**: Fake consensus (people agree publicly but disagree privately). Dominators steamroll minority. + +### Consent (Sociocracy) + +**Definition**: No one has a "principled objection" (i.e., decision is "safe to try"). + +**Process**: Propose decision. Ask "Any objections?" If objection, explore: Is it principled (violates values, causes harm) or preference (I'd rather do X)? Principled → revise proposal. Preference → document but proceed. + +**Pros**: Faster than consensus, surfaces critical objections, empowers minority voice + +**Cons**: Requires discipline (distinguishing principled vs preference), unfamiliar to many + +**Use when**: Need speed but also safety. Experimental decisions (can reverse if fails). Sociocratic orgs. + +### Majority Vote + +**Definition**: >50% wins (or 2/3, or other threshold). + +**Process**: Present options, clarify, vote (show of hands, poll, secret ballot). Majority wins. + +**Pros**: Fast, clear outcome, democratic + +**Cons**: Minority may feel unheard, low buy-in from losers, binary (can't combine ideas) + +**Use when**: Simple choices, time pressure, democratic process expected, low controversy + +**Variations**: +- **Ranked choice**: Vote for 1st, 2nd, 3rd choice. Eliminates least popular iteratively. +- **Dot voting**: Each person gets N dots to allocate across options. Visual, quick prioritization. + +### Advisory (Input-Driven) + +**Definition**: One person makes decision after gathering input from group. + +**Process**: Present options, gather feedback/concerns, decision-maker weighs input and decides. Announces decision with rationale. + +**Pros**: Fast, accountable (one person owns), scalable (doesn't require everyone to agree) + +**Cons**: Can feel top-down if not communicated well, decision-maker may ignore input + +**Use when**: Decision-maker clear, they have context others lack, time pressure, precedent for this authority + +**Keys**: Announce upfront ("I'll make call with your input"), genuinely consider input, explain rationale. + +### Delegation + +**Definition**: Empower a subset (person or small group) to decide within constraints. + +**Process**: Define decision space ("You can decide X, Y, Z within budget $N and timeframe T"). Delegate. Group decides autonomously. Reports back. + +**Pros**: Scales well, develops autonomy, fast (no coordination overhead) + +**Cons**: Requires trust, may make suboptimal choice (lack full context), others may feel excluded + +**Use when**: Decision is specialized (subset has expertise), trust high, decision reversible, empowerment valued + +### Comparison Table + +| Method | Speed | Buy-in | Use When | +|--------|-------|--------|----------| +| **Consensus** | Slow | Very High | High-stakes, irreversible, time available | +| **Consent** | Medium | High | Experimental, need safety + speed | +| **Majority Vote** | Fast | Medium | Simple choice, democratic process | +| **Advisory** | Fast | Medium | Clear decision-maker, time pressure | +| **Delegation** | Very Fast | Varies | Specialized, trust high, empowerment | + +--- + +## 6. Remote Facilitation Best Practices + +### Synchronous (Live Video) + +**Challenges**: Harder to read body language, tech issues, "Zoom fatigue", harder to manage participation. + +**Best practices**: +- **Cameras on** (if possible, respect privacy): Increases engagement, body language visible +- **Mute when not speaking**: Reduces background noise +- **Use chat**: Parallel channel for questions, links, emoji reactions, jokes (humanizes) +- **Breakout rooms**: Small groups for discussion (easier than 15 people on main call) +- **Visual board**: Mural, Miro, Google Jamboard. Everyone contributes simultaneously. +- **Shorter sessions**: 90 min max without break (Zoom fatigue real). Prefer 60 min. +- **More breaks**: Every 45-60 min (5 min break). People need screen rest. +- **Explicit turn-taking**: Harder to read cues. Use hand-raise feature, or round robin. +- **Share agenda in chat**: Pin message or share screen. Easy reference. +- **Tech check**: "Can everyone see screen? Hear me okay?" at start. + +**Tools**: +- **Video**: Zoom, Google Meet, Microsoft Teams +- **Collaboration**: Mural, Miro, Figma, Google Jamboard, Lucidspark +- **Voting**: Slido, Mentimeter, Poll Everywhere, built-in Zoom polls +- **Anonymous Q&A**: Slido, Mentimeter (reduces hierarchy) + +### Asynchronous + +**When to use**: Global teams (time zones), deep thinking needed, no urgency, writing > talking. + +**Process**: +1. **Post prompt**: Clear question, context, examples, deadline (24-48h) +2. **Async responses**: People respond in shared doc, thread, video (Loom) +3. **Synthesize**: Facilitator (or AI) summarizes themes, patterns, questions +4. **Sync session** (optional): Short call (30-60 min) to discuss, clarify, decide based on async input +5. **Document decision**: Write up, share with all + +**Best practices**: +- **Clear prompts**: Specific questions, not vague ("What do you think about X?"). Example: "What are the top 3 risks for this feature launch? For each, suggest a mitigation." +- **Deadline**: Give 24-48h for responses. Longer → people forget. +- **Acknowledge contributions**: React to comments, thank people for input +- **Thread discussions**: Use threaded replies (Slack, Notion, Google Docs comments) so conversations organized +- **Synthesis required**: Don't expect participants to read 50 comments. Facilitator summarizes. + +**Tools**: +- **Docs**: Google Docs (comments), Notion, Confluence +- **Threads**: Slack, Microsoft Teams, Discord +- **Video**: Loom (async video responses) +- **Forms**: Google Forms, Typeform (structured input) + +### Hybrid (Some In-Person, Some Remote) + +**Hardest to facilitate well**: Remote folks feel like second-class participants. + +**Best practices**: +- **Equalize participation**: Use digital tools even for in-person folks (everyone on laptop + Mural, not whiteboard that remote can't access) +- **Camera for room**: If in-person group, aim camera at room so remote see body language and who's speaking +- **Explicit turn-taking**: "Let's hear from remote folks first, then in-person." +- **Assign in-room advocate**: Someone in-person watches chat, relays remote comments aloud +- **Minimize hybrid if possible**: Strongly prefer all-remote or all-in-person. Hybrid is hardest. + +--- + +## Summary + +**Pattern selection**: Match pattern to objective (divergent brainstorm, convergent decision, alignment, retro, design sprint). Consider group size, time available. + +**Agenda design**: Follow diverge-converge flow, time-box ruthlessly, design for energy arc (breaks every 60-90 min, vary modalities). + +**Facilitation techniques**: Ensure participation (round robin, 1-2-4-All, silent writing, breakouts), manage time (visible timer, buffer), capture outputs (visible board, scribe, structured notes). + +**Difficult dynamics**: Handle dominators (round robin, interrupt gently), silent participants (writing first, pairs, direct invite), conflict (surface it, clarify trade-offs, decision method), tangents (parking lot), low energy (breaks, energizers, stop early), power dynamics (boss speaks last, anonymous). + +**Decision methods**: Consensus (slow, high buy-in), consent (safe to try, faster), vote (fast, democratic), advisory (input-driven, one person decides), delegation (empower subset). Choose based on stakes, time, trust. + +**Remote facilitation**: Synchronous (cameras on, chat, visual boards, shorter sessions, more breaks, explicit turn-taking). Asynchronous (clear prompts, deadlines, synthesis required). Hybrid (hardest - equalize participation, minimize if possible). + +**Final principle**: Facilitation is about process, not content. Facilitator guides how group works together, stays neutral on what group decides. Strong process → better outcomes. diff --git a/skills/facilitation-patterns/resources/template.md b/skills/facilitation-patterns/resources/template.md new file mode 100644 index 0000000..674a7c2 --- /dev/null +++ b/skills/facilitation-patterns/resources/template.md @@ -0,0 +1,366 @@ +# Facilitation Patterns Templates + +Quick-start templates for session design, agenda building, logistics, and follow-up. + +## Workflow + +``` +Facilitation Planning Progress: +- [ ] Step 1: Define session objectives +- [ ] Step 2: Select facilitation pattern +- [ ] Step 3: Design agenda +- [ ] Step 4: Prepare materials and logistics +- [ ] Step 5: Facilitate the session +- [ ] Step 6: Close and follow up +``` + +**Step 1**: Define objectives → Use [Session Design Template](#session-design-template) + +**Step 2**: Select pattern → See SKILL.md [Common Patterns](../SKILL.md#common-patterns) + +**Step 3**: Design agenda → Use [Agenda Design Template](#agenda-design-template) + +**Step 4**: Prepare logistics → Use [Logistics Checklist](#logistics-checklist) + +**Step 5**: Facilitate → Use [Facilitation Script Template](#facilitation-script-template) + +**Step 6**: Close and follow up → Use [Closing and Follow-up Template](#closing-and-followup-template) + +--- + +## Session Design Template + +**Session name**: [Give it a clear, descriptive name] + +**Date/Time**: [When, how long] + +**Facilitator**: [Who runs it] **Scribe**: [Who takes notes] + +### Objective + +**Primary goal** (complete this sentence): +"By the end of this session, we will have [specific outcome]." + +Examples: +- Decided on Q2 roadmap priorities (top 5 features) +- Generated 30+ ideas for customer onboarding improvements +- Aligned on product vision and 6-month milestones +- Identified 3 improvements from sprint retrospective + +**Success criteria**: How will you know if session succeeded? +- [ ] [Measurable outcome 1] +- [ ] [Measurable outcome 2] +- [ ] [Participants report session was valuable (feedback score ≥4/5)] + +### Participants + +| Name | Role | Why invited | Required? | +|------|------|-------------|-----------| +| [Person 1] | [Title] | [Decision-maker, subject matter expert, implementer, stakeholder] | Yes/No | +| [Person 2] | [Title] | [Reason] | Yes/No | +| [Person 3] | [Title] | [Reason] | Yes/No | + +**Total**: [N people] (ideal: 5-8 for discussion, up to 20 for presentation+Q&A, 3-5 for decision) + +**Power dynamics to manage**: [Boss in room?

Underestimating CAC makes unit economics look better than reality. Common miss: excluding sales team salaries. + +2. **True variable costs**: Only include costs that scale with each unit (COGS, hosting per user, transaction fees). Don't include fixed costs (rent, core engineering). LTV calculation requires accurate margin. + +3. **Cohort-based LTV**: Don't average across all customers. Early cohorts ≠ recent cohorts. Track retention curves by cohort (acquisition month/channel). LTV should be based on observed retention, not assumptions. + +4. **Time horizon matters**: LTV is a prediction. Use conservative assumptions. For new products, LTV estimates are unreliable (insufficient data). Weight recent cohorts more heavily. + +5. **Payback period vs. LTV/CAC**: Both matter. High LTV/CAC but long payback (>18 months) strains cash. Fast payback (<6 months) allows rapid reinvestment. Optimize for both. + +6. **Channel-level analysis**: Blended metrics hide truth. CAC and LTV vary by channel (paid search vs. referral vs. content). Analyze separately to optimize spend. + +7. **Retention is king**: Small changes in churn have exponential impact on LTV. Improving monthly churn from 5% to 4% increases LTV by 25%. Retention improvements > acquisition improvements. + +8. **Gross margin floor**: Need ≥60% gross margin for SaaS, ≥40% for e-commerce to be viable. Low margin means high LTV/CAC ratio still yields poor cash flow. + +**Common pitfalls:** + +- ❌ **Ignoring churn**: Assuming customers stay forever. Reality: churn compounds. Use cohort retention curves. +- ❌ **Vanity LTV**: Using unrealistic retention (e.g., 5 year LTV with 1 month of data). Stick to observed behavior. +- ❌ **Blended CAC**: Mixing profitable and unprofitable channels. Break down by channel, segment, cohort. +- ❌ **Not updating**: Unit economics change as product, market, competition evolve. Re-calculate quarterly. +- ❌ **Missing costs**: Forgetting support costs, payment processing fees, fraud losses, refunds. Track everything. +- ❌ **Premature scaling**: Growing before unit economics work (LTV/CAC <2:1).

Break down by channel. +2. **LTV requires cohort data**: Track retention by cohort, extrapolate conservatively. Don't rely on averages. +3. **Contribution margin sets ceiling**: Need high margin (>60% SaaS, >40% ecommerce) for viable economics. +4. **Both ratio and payback matter**: 5:1 ratio with 24-month payback < 3:1 with 6-month payback (cash efficiency). +5. **Retention > Acquisition**: Small churn improvements have exponential LTV impact. Prioritize retention. +6. **Channel-level analysis**: Blended metrics hide truth. Analyze CAC/LTV per channel, optimize spend accordingly. +7. **Update quarterly**: Unit economics evolve with scale, market changes, competition.

Analyze each separately. +5. **Fixed vs variable costs**: Don't include fixed costs (engineering, rent) in contribution margin. Only variable costs that scale with units. +6. **Not updating**: Re-calculate quarterly.

Treat as sacred. One interruption destroys 20+ min of flow. Schedule deep work during peak energy (usually mornings). + +2. **Respect Parkinson's Law**: Work expands to fill available time. Shorter timeboxes force prioritization and prevent perfectionism. Better: 90 min timebox with clear outcome than open-ended "work on this." + +3. **Actually identify 80/20**: Most people work on 80% (low-impact). Force rank tasks by impact. Top 20% should get 80% of your focus time. Cut, delegate, or batch the rest. + +4. **Energy > Time**: 8 hours tired < 4 hours energized. Don't schedule deep work during low-energy troughs. Match intensity to energy. Trough = admin/meetings, not complex thinking. + +5. **Build in buffer**: Don't timebox every minute. 20% unscheduled time for unexpected issues, overflow, breaks. Over-scheduled = fragile. One delay cascades. + +6. **Hard stops prevent burnout**: Define end-of-day (e.g., 5pm hard stop). No evening work unless true emergency. Constrained time forces prioritization, endless time enables procrastination. + +7. **Breaks are non-negotiable**: 90 min deep work → 10-15 min break. Walk, stretch, look outside. Don't skip breaks to "power through." Focus degrades exponentially after 90-120 min. + +8. **Measure focus quality, not hours**: 3 hours deep work > 8 hours distracted. Track how many focus blocks completed per week, not total hours. Quality over quantity. + +**Common pitfalls:** + +- ❌ **No real deep work blocks**: Calendar full of meetings, "focus time" constantly interrupted. Protect minimum 2-3× 90-min blocks per week. +- ❌ **Ignoring 80/20**: Everything feels important. Force rank. If you can't identify top 20%, ask: "If I could only work 10 hours this week, what would I do?" +- ❌ **Timeboxing trivia**: Scheduling every email, every Slack message. Batch low-value tasks, don't timebox them individually. +- ❌ **Skipping breaks**: "I'll break after I finish this." Then work 4 hours straight, output quality tanks. Use timer, force breaks. +- ❌ **Peak hours on admin**: Checking email at 9am (peak energy). Save admin for afternoon trough. Peak hours = deep work only. +- ❌ **Overcommitting**: Timeboxing 10 hours of work into 8-hour day. Be realistic.

[Advanced Strategies](#6-advanced-strategies) + +--- + +## 1. Deep Work and Focus Blocks + +### What Is Deep Work? + +**Definition** (Cal Newport): "Professional activities performed in a state of distraction-free concentration that push your cognitive capabilities to their limit. These efforts create new value, improve your skill, and are hard to replicate." + +**Shallow work**: Non-cognitively demanding tasks performed while distracted. Easy to replicate, low value creation. + +**Why deep work matters**: +- Creates disproportionate value (complex problems solved, creative breakthroughs) +- Builds rare skills faster (deliberate practice requires deep focus) +- Produces flow states (intrinsically satisfying, high-quality output) +- Increasingly rare in distracted world (competitive advantage) + +### Setting Up Deep Work Blocks + +**Pre-work (5-10 min before block)**: +1. **Clear outcome**: What specific output by end of session? (e.g., "Draft sections 1-3 of spec" not "work on spec") +2. **Gather resources**: All documents, links, code, notes accessible. No mid-session searching. +3. **Eliminate distractions**: + - Quit Slack/Teams (not just close, quit) + - Close email tab/app + - Phone in different room or airplane mode + - Close all browser tabs except work-related + - Set status to DND/Busy + - Noise-canceling headphones if open office +4. **Set timer**: Visual timer (not phone) to track remaining time + +**During deep work**: +- **Single task only**: No context-switching. If new task occurs, write in notebook for later. +- **No checking**: Email, Slack, news, social media forbidden. Even "quick check" destroys 15+ min of focus. +- **Capture tangents**: Keep notebook for off-topic ideas. Write them down, return to focus. +- **Push through resistance**: First 10-15 min feels hard. Push through. Flow state arrives ~15-20 min in. + +**After deep work**: +- **Take break**: Non-negotiable. Walk, stretch, look outside. Don't skip. +- **Capture progress**: Quick note on what got done, what's next session. +- **Resist shallow work**: Don't immediately check email. Take actual break first. + +### Optimal Duration + +**Research findings** (Ericsson, Newport, Csikszentmihalyi): +- **Beginners**: 60-90 min max before fatigue +- **Experienced**: 90-120 min max +- **Elite experts**: 4 hours per day max across 2-3 sessions + +**Why 90 min is magic number**: +- Matches ultradian rhythm (90-120 min cycles of alertness) +- Long enough for flow state, short enough to sustain intensity +- Human attention naturally declines after ~90 min + +**Progressive training**: +- Week 1-2: 25 min (Pomodoro) × 2 per day +- Week 3-4: 50 min × 2 per day +- Week 5-6: 90 min × 2 per day +- Maintenance: 90 min × 2-3 per day + +**Don't exceed capacity**: 3 hours deep work (2× 90min blocks) > 8 hours shallow work. Quality over quantity. + +--- + +## 2. Timeboxing Techniques + +### Parkinson's Law + +**"Work expands to fill the time available for its completion."** - C. Northcote Parkinson + +**Implication**: Give yourself less time, get more done. Time constraints force: +- Prioritization (what really matters?) +- Elimination of perfectionism (good enough > perfect never shipped) +- Faster decision-making (no time for overthinking) + +**Example**: +- Task: "Write product spec" +- Open-ended: Takes 3 weeks (perfectionism, scope creep, procrastination) +- Timeboxed (4 hours): Forces clarity, ships in 1 day + +### Timeboxing Methods + +**Fixed Duration, Flexible Scope** (Agile approach): +- Allocate fixed time (e.g., 90 min) +- Define minimum viable output (MVP) +- Accept that you may not finish everything +- Better than: Flexible time, fixed scope (leads to endless expansion) + +**Example** (writing blog post): +- Timebox: 2 hours +- MVP: Draft with intro, 3 main points, conclusion (even if rough) +- Nice-to-have: Polish, examples, images (skip if time runs out) +- Ship MVP. Perfect later if needed. + +**Hard Deadlines**: +- Schedule end time, not just start time +- Calendar block: 9:00-10:30am (not "9am - ?") +- Set alarm for 10 min before end (wrap-up time) +- Hard stop at end time, even if incomplete + +**Progressive Timeboxing** (for large projects): +- Break into phases, timebox each +- Example (feature development): + - Phase 1: Research & design (4 hours) + - Phase 2: Implementation (8 hours across 4× 2hr blocks) + - Phase 3: Testing & polish (4 hours) +- Ship at end of each phase or pivot if needed + +### When to Use Each Duration + +**25 min (Pomodoro)**: +- High-resistance tasks (procrastination strong) +- Building focus habit (beginners) +- Routine tasks (email, code reviews) +- Low energy but need to make progress + +**50-60 min**: +- Moderate complexity (not deep work, not trivial) +- Mixed tasks (some focus, some collaboration) +- Good for meetings (default 30/60 min in most calendars) + +**90 min (Deep Work)**: +- Complex thinking (strategy, architecture, writing) +- Creative work (design, coding new features) +- Peak energy periods (morning for most) +- Maximum 3× per day + +**2-4 hours (Maker's Schedule)**: +- Breakthrough work (research paper, product launch) +- Flow-state tasks (coding, writing, design) +- Once per week minimum for knowledge workers +- Requires complete calendar control + +--- + +## 3. Execution Discipline + +### Eliminating Distractions + +**Phone discipline**: +- Physical separation (different room) > Airplane mode > Face down +- Why: "I'll just check once" never works. Checking is compulsive. +- Emergency: Give family/manager alternate contact (desk phone, colleague) + +**Slack/Teams/Email**: +- Quit app (not minimize) during deep work +- Schedule checks: 11am, 4pm (2× per day max) +- Set auto-responder: "Checking email 2× daily. Urgent? Text/call." +- Batch responses: Write all replies in one session + +**Browser discipline**: +- Close all tabs except work-related (before deep work) +- Block sites during focus (Freedom, Cold Turkey, LeechBlock) +- Use separate browser/profile for work vs. personal + +**Environmental setup**: +- Visual signal (headphones, sign) to discourage interruptions +- Office door closed (if available) +- Book conference room for deep work (escape open office) +- Work from home on deep work days (if remote possible) + +### Managing Interruptions + +**Protocol for "urgent" interruptions**: +1. **Defer**: "I'm in focus time until 11am. Can it wait?" (90% can) +2. **Delegate**: "Can [colleague] help?" (transfer to someone with slack capacity) +3. **Batch**: "Send me details, I'll address at 11am" (add to batch list) +4. **Emergency only**: True emergency (production down, customer escalation) + +**Training others**: +- Communicate schedule: "Deep work 9-11am daily, no interruptions" +- Be consistent: If you allow interruptions sometimes, they'll keep trying +- Offer alternatives: "Free after 2pm for questions" + +### Beating Procrastination + +**Why we procrastinate**: +- Task ambiguity (unclear what to do) +- Perceived difficulty (feels overwhelming) +- Perfectionism (fear of imperfect output) +- Lack of deadlines (infinite time = infinite delay) + +**Solutions**: +1. **Break into tiny first step**: "Write introduction paragraph" not "Write chapter" +2. **Use 25-min Pomodoro**: Commit to just 25 min. Lower activation energy. +3. **Set artificial deadline**: "Draft by 5pm today" creates urgency +4. **Remove perfection**: "First draft is allowed to suck" (can revise later) +5. **Start with easiest part**: Build momentum, then tackle hard part + +**Two-Minute Rule**: If task <2 min, do immediately. Don't timebox or add to list. Clear small tasks fast. + +--- + +## 4. Energy Management and Optimization + +### Circadian Rhythms and Peak Hours + +**Typical energy pattern** (most people): +- **6-9am**: Peak (early risers) - deep work optimal +- **9am-12pm**: Peak (most people) - deep work optimal +- **12-2pm**: Lunch dip - social/meetings work well +- **2-3pm**: Trough (post-lunch crash) - worst time for focus +- **3-5pm**: Recovery - moderate work, planning +- **Evening**: Low - rest, routine, NOT deep work + +**Individual variation**: +- Track your energy for 1 week (rate 1-5 every 2 hours) +- Plot pattern: When peak? When trough? +- Schedule accordingly: Deep work during peak, admin during trough + +**Chronotype differences**: +- **Larks (morning people)**: Peak 6-10am +- **Owls (night people)**: Peak 4-9pm +- **Third birds (majority)**: Peak 10am-1pm + +### Energy Optimization Strategies + +**Protect peak hours ruthlessly**: +- No meetings during peak (9-12am for most) +- No email/Slack during peak +- Deep work only during peak +- Schedule everything else around peak + +**Match intensity to energy**: +| Energy Level | Task Type | Examples | +|--------------|-----------|----------| +| **Peak** | Deep work | Writing, coding, strategy, design | +| **High** | Moderate work | Code reviews, planning, learning | +| **Medium** | Meetings | 1:1s, standups, collaboration | +| **Low** | Admin | Email, expense reports, organizing | +| **Very Low** | Rest | Walk, nap, reading (not work) | + +**Energy recovery**: +- **Breaks between blocks**: 10-15 min every 90 min (non-negotiable) +- **Lunch away from desk**: Actual break, not "working lunch" +- **Walking meetings**: Movement boosts energy for afternoon +- **20-min power nap**: (2-3pm) resets energy if crash is severe +- **Hard stop at 5pm**: Evening rest prevents next-day burnout + +**Sleep is non-negotiable**: +- 7-9 hours per night (not negotiable despite "hustle culture") +- Insufficient sleep → degraded focus, poor decisions, low output +- One all-nighter destroys focus for 3-4 days + +--- + +## 5. 80/20 Principle Applications + +### Beyond Task Lists + +**80/20 applies everywhere**: +- **Code**: 20% of functions contain 80% of bugs +- **Customers**: 20% of customers generate 80% of revenue +- **Features**: 20% of features drive 80% of usage +- **Meetings**: 20% of meetings produce 80% of value +- **Relationships**: 20% of people provide 80% of support/value + +**Implication**: Identify and focus on vital 20%, minimize/eliminate trivial 80%. + +### Identifying Your 20% + +**Questions to ask**: +1. "If I could only work 10 hours this week, what would I do?" +2. "Which tasks, if done excellently, make everything else easier or unnecessary?" +3. "What creates 10× value vs. 1× value?" +4. "What will matter in 6 months? 12 months?" +5. "What am I uniquely positioned to do? (vs. delegate/eliminate)" + +**Force ranking exercise**: +- List all tasks/projects/commitments +- Force rank 1 to N (no ties allowed) +- Top 20% = vital few +- Bottom 80% = delegate, defer, eliminate, or batch + +### Eliminating/Delegating the 80% + +**Strategies**: +- **Eliminate**: Stop doing entirely. Many tasks done by inertia, not necessity. +- **Delegate**: Transfer to someone else (team member, contractor, automation). +- **Defer**: "Someday/maybe" list. Revisit quarterly. Most stay deferred forever (good). +- **Batch**: Group low-value tasks (email, admin) into single session vs. scattered throughout day. +- **Automate**: Script, template, or tool replaces manual work. + +**Permission to say no**: If not in top 20%, default answer is "no" or "not now." Saying yes to everything means no time for vital few. + +--- + +## 6. Advanced Strategies + +### Maker's Schedule vs. Manager's Schedule + +**Manager's Schedule** (Paul Graham): +- Day divided into 1-hour blocks +- Calendar full of meetings +- Context-switching between tasks +- Works for coordination, decisions, people management + +**Maker's Schedule**: +- Day divided into half-day or full-day blocks +- Uninterrupted time for creating (code, writing, design) +- Context-switching is enemy +- Works for technical/creative work + +**Conflict**: Managers schedule "quick 30-min meeting" that destroys maker's 4-hour block. + +**Solution for makers**: +- **Office hours**: Available for meetings Tue/Thu 2-5pm only +- **Deep work blocks**: Mon/Wed/Fri mornings protected (no meetings) +- **Communicate**: "I'm on maker's schedule. Half-days only for focus work." + +### Theme Days + +Dedicate each day to single theme (reduce context-switching across days). + +**Example**: +- **Monday**: Deep work on Project A (code/write all day) +- **Tuesday**: Meetings + collaboration (batched) +- **Wednesday**: Deep work on Project B +- **Thursday**: Meetings + admin +- **Friday**: Planning, learning, cleanup + +**Benefits**: +- Single context per day (vs. switching hourly) +- Easier to protect full days vs. hour blocks +- Clearer boundaries (teammates know Monday = no meetings) + +### Strategic Quitting + +**Sunk cost fallacy**: Continuing projects/tasks because "already invested time." + +**Better**: Evaluate based on future value, not past investment. + +**Quarterly review**: +- List all commitments/projects +- For each: "If I weren't already doing this, would I start today?" +- If no → quit, even if significant past investment + +**Example**: Drop committee membership (2 hours/week), reclaim 100 hours/year for vital few. + +### Deep Work Rituals + +**Location ritual**: +- Same place every day for deep work (trains brain: "This desk = focus mode") +- Or: Dedicated space (library, coffee shop) exclusively for deep work + +**Time ritual**: +- Same time every day (e.g., 9-11am) +- Brain learns pattern, enters focus mode faster + +**Startup ritual** (5-10 min before deep work): +- Make coffee/tea +- Review session goal +- Close distractions +- Set timer +- Begin + +**Shutdown ritual** (end of day): +- Review what got done +- Plan tomorrow's top priority +- Close all work tabs/apps +- Clear desk +- "Shutdown complete" phrase (signals brain: work done, rest mode) + +### Accountability Systems + +**Public commitment**: +- Share goals with colleague/friend +- Weekly check-in on deep work hours completed +- Accountability partner does same + +**Tracking**: +- Log focus blocks completed (quality, duration, distractions) +- Review weekly: "Completed X hours deep work vs. Y hours planned" +- Adjust next week based on data + +**Reward systems**: +- Small reward after completing focus block (walk, good coffee, 15-min break) +- Larger reward after productive week (nice meal, movie, guilt-free weekend) + +**Commitment devices**: +- Beeminder (pay money if don't meet goal) +- StickK (pledge to charity if fail) +- Public declaration (blog, Twitter) creates social pressure + +### Focus Stacking + +**Concept**: Use momentum from one focus block to fuel next. + +**Pattern**: +- 90 min deep work → 15 min break → 90 min deep work +- Same general topic/project (don't switch contexts) +- Total: 3 hours deep work in one morning + +**When to stack**: +- Critical deadline approaching +- High-complexity work requiring sustained thought +- Peak energy day (well-rested, healthy) + +**When NOT to stack**: +- Low energy (quality degrades) +- Multiple unrelated projects (context-switching negates benefit) +- After meetings or interruptions (focus already fractured) + +**Maximum**: 2 stacked blocks (3 hours total). Beyond that, quality tanks. + +--- + +## Key Takeaways + +1. **Deep work is trainable**: Start with 25-min Pomodoros, build to 90-min blocks over weeks. Don't expect instant focus. + +2. **Parkinson's Law is your friend**: Shorter timeboxes force prioritization and prevent perfectionism. Constrain time to boost output. + +3. **Energy > Time**: 3 hours peak-energy deep work beats 8 hours exhausted shallow work. Schedule deep work during peak hours only. + +4. **80/20 requires discipline**: Everything feels important. Force rank ruthlessly. Top 20% gets 80% of focus time. Say no to the rest. + +5. **Distractions are enemy**: One Slack check destroys 15+ min of focus. Eliminate during deep work. Quit apps, not just minimize. + +6. **Breaks are productivity tools**: Skipping breaks degrades focus exponentially. 90 min work → 15 min break is optimal cycle. + +7. **Consistency beats intensity**: 2 hours deep work daily (10 hrs/week) beats one 12-hour marathon followed by burnout. Sustainable pace wins. diff --git a/skills/focus-timeboxing-8020/resources/template.md b/skills/focus-timeboxing-8020/resources/template.md new file mode 100644 index 0000000..6cd66a9 --- /dev/null +++ b/skills/focus-timeboxing-8020/resources/template.md @@ -0,0 +1,380 @@ +# Focus, Timeboxing, and 80/20 Templates + +Quick-start templates for identifying high-impact work, designing focus blocks, and timeboxing your schedule. + +## 80/20 Analysis Template + +**Goal**: Identify the vital 20% of tasks that drive 80% of your results. + +### Step 1: Brain Dump All Tasks + +List everything competing for your attention (work tasks, projects, meetings, admin): + +1.

Yes → Assign senior rep. No → Is deal >$10k? Yes → Assign mid-level. No → Self-serve." +- **When works**: Clear decision structure, limited information needed +- **When fails**: Nuanced decisions, exceptions common + +## Guardrails + +**Critical requirements:** + +1. **Know when heuristics work vs. fail**: Heuristics excel in stable, familiar environments with time pressure. They fail in novel, deceptive contexts (adversarial, misleading information). Don't use recognition heuristic when advertising creates false signals. + +2. **Satisficing ≠ low standards**: "Good enough" threshold must be calibrated. Set based on cost of continued search vs. value of better option. Too low → poor decisions. Too high → analysis paralysis. + +3. **Checklists for critical steps only**: Don't list every trivial action. Focus on steps that (1) are skipped often, (2) have serious consequences if missed, (3) not immediately obvious. Short checklists used > long checklists ignored. + +4. **READ-DO for novices, DO-CONFIRM for experts**: Match format to user expertise. Forcing experts into READ-DO creates resistance and abandonment. Let experts flow, confirm after. + +5. **Test heuristics empirically**: Don't assume rule works. Test on historical cases. Compare heuristic decisions to optimal decisions. If accuracy <80%, refine or abandon. + +6. **Bias awareness is not bias elimination**: Knowing availability bias exists doesn't prevent it. Heuristics are unconscious. Need external checks (checklists, peer review, base rates) to counteract biases. + +7. **Update heuristics when environment changes**: Rules optimized for past may fail in new context. Market shifts, technology changes, competitor strategies evolve. Re-validate quarterly. + +8. **Forcing functions beat reminders**: "Don't forget X" fails. "Can't proceed until X done" works. Build constraints (e.g., deployment script requires all tests pass) rather than relying on memory. + +**Common pitfalls:** + +- ❌ **Heuristic as universal law**: "Always choose recognized brand" fails when dealing with deceptive advertising or niche quality. +- ❌ **Checklist too long**: 30-item checklist gets skipped. Keep to 5-10 critical items max. +- ❌ **Ignoring base rates**: "This customer seems like they'll buy" (representativeness heuristic) vs. "Only 2% of leads convert" (base rate). Use base rates to calibrate intuition. +- ❌ **Anchoring on first option**: "First candidate seems good, let's hire" without considering alternatives. Set satisficing threshold, then evaluate multiple options. +- ❌ **Checklist as blame shield**: "I followed checklist, not my fault" ignores responsibility to think. Checklists augment judgment, don't replace it. +- ❌ **Not testing heuristics**: Assume rule works without validation.

(Recognize Detroit → Larger) + - **Works when**: Recognition correlates with criterion (r > 0.5) + - **Fails when**: Misleading advertising, niche quality + +2. **Take-the-Best**: Rank cues by validity, use highest-validity cue that discriminates. Ignore others. + - **Example**: Hiring based on coding test score alone (if validity >70%) + - **Works when**: One cue dominates, environment stable + - **Fails when**: Multiple factors interact, no dominant cue + +3. **1/N Heuristic**: Divide resources equally among N options. + - **Example**: Investment portfolio - equal weight across stocks + - **Works when**: No information on which option better, diversification reduces risk + - **Fails when**: Clear quality differences exist + +### Satisficing (Herbert Simon) + +**Concept**: Search until option meets aspiration level (threshold), then stop. Don't optimize. + +**Formula**: +``` +Aspiration level = f(past outcomes, time pressure, search costs) +``` + +**Adaptive satisficing**: Lower threshold if no options meet it after K searches. Raise threshold if too many options qualify. + +**Example**: +- Job search: "Salary ≥$120k, culture fit ≥7/10" +- After 20 applications, no offers → Lower to $110k +- After 5 offers all meeting bar → Raise to $130k + +### Ecological Rationality + +**Key insight**: Heuristic's success depends on environment, not complexity. + +**Environment characteristics**: +- **Redundancy**: Multiple cues correlated (take-the-best works) +- **Predictability**: Patterns repeat (recognition heuristic works) +- **Volatility**: Rapid change (simple heuristics adapt faster than complex models) +- **Feedback speed**: Fast feedback enables learning (trial-and-error refinement) + +**Mismatch example**: Using recognition heuristic in adversarial environment (advertising creates false recognition) → Fails + +--- + +## 3. Checklist Design Principles + +### Atul Gawande's Checklist Principles + +Based on research in aviation, surgery, construction: + +1. **Keep it short**: 5-9 items max. Longer checklists get skipped. +2. **Focus on killer items**: Steps that are often missed AND have serious consequences. +3. **Verb-first language**: "Verify backups complete" not "Backups" +4. **Pause points**: Define WHEN to use checklist (before start, after critical phase, before finish) +5. **Fit on one page**: No scrolling or page-flipping + +### READ-DO vs. DO-CONFIRM + +**READ-DO** (Challenge-Response): +- Read item aloud → Perform action → Confirm → Next item +- **Use for**: Novices, unfamiliar procedures, irreversible actions +- **Example**: Surgical safety checklist (WHO) + +**DO-CONFIRM**: +- Perform entire procedure from memory → Then review checklist to confirm all done +- **Use for**: Experts, routine procedures, flow state important +- **Example**: Aviation pre-flight (experienced pilots) + +**Which to choose?**: +- Expertise level: Novice → READ-DO, Expert → DO-CONFIRM +- Familiarity: First time → READ-DO, Routine → DO-CONFIRM +- Consequences: Irreversible (surgery) → READ-DO, Reversible → DO-CONFIRM + +### Forcing Functions and Fail-Safes + +**Forcing function**: Design that prevents proceeding without completing step. + +**Examples**: +- Car won't start unless seatbelt fastened +- Deployment script fails if tests not passing +- Door won't lock if key inside + +**vs. Checklist item**: Checklist reminds, but can be ignored. Forcing function prevents. + +**When to use forcing function instead of checklist**: +- Critical safety step (must be done) +- Automatable check (can be enforced by system) +- High compliance needed (>99%) + +**When checklist sufficient**: +- Judgment required (can't automate) +- Multiple valid paths (flexibility needed) +- Compliance good with reminder (>90%) + +--- + +## 4. Validating Heuristics and Checklists + +### Testing Heuristics + +**Retrospective validation**: Test heuristic on historical cases. + +**Method**: +1. Collect past decisions (N ≥ 30 cases) +2. Apply heuristic to each case (blind to actual outcome) +3. Compare heuristic decision to actual outcome +4. Calculate accuracy: % cases where heuristic would've chosen correctly + +**Target accuracy**: ≥80% for good heuristic. <70% → Refine or abandon. + +**Example** (Hiring heuristic): +- Heuristic: "Hire candidates from top 10 tech companies" +- Test on past 50 hires +- Outcome: 40/50 (80%) from top companies succeeded, 5/10 (50%) from others +- **Conclusion**: Heuristic valid (80% > 50% base rate) + +### A/B Testing Heuristics + +**Prospective validation**: Run controlled experiment. + +**Method**: +1. Group A: Use heuristic +2. Group B: Use existing method (or random) +3. Compare outcomes (quality, speed, consistency) + +**Example**: +- A: Customer routing by fast & frugal tree +- B: Customer routing by availability +- **Metrics**: Response time, resolution rate, customer satisfaction +- **Result**: A faster (20% ↓ response time), higher satisfaction (8.2 vs. 7.5) → Adopt heuristic + +### Checklist Validation + +**Error rate measurement**: + +**Before checklist**: +- Track error rate for procedure (e.g., deployments with failures) +- Baseline: X% error rate + +**After checklist**: +- Introduce checklist +- Track error rate for same procedure +- New rate: Y% error rate +- **Improvement**: (X - Y) / X × 100% + +**Target**: ≥50% error reduction. If <25%, checklist not effective. + +**Example** (Surgical checklist): +- Before: 11% complication rate +- After: 7% complication rate +- **Improvement**: (11 - 7) / 11 = 36% reduction (good, continue using) + +--- + +## 5. Refinement and Iteration + +### When Heuristics Fail + +**Diagnostic questions**: +1. **Wrong cue**: Are we using the best predictor? Try different criterion. +2. **Threshold too high/low**: Should we raise/lower aspiration level? +3. **Environment changed**: Did market shift, competition intensify, technology disrupt? +4. **Exceptions accumulating**: Are special cases becoming the norm? Need more complex rule. + +**Refinement strategies**: +- **Add exception**: "Use heuristic EXCEPT when [condition]" +- **Adjust threshold**: Satisficing level up/down based on outcomes +- **Switch cue**: Use different criterion if current one losing validity +- **Add layer**: Convert simple rule to fast & frugal tree (2-3 questions max) + +### When Checklists Fail + +**Diagnostic questions**: +1. **Too long**: Are people skipping because overwhelming? → Cut to killer items only. +2. **Wrong format**: Are experts resisting READ-DO? → Switch to DO-CONFIRM. +3. **Missing critical step**: Did error happen that checklist didn't catch? → Add item. +4. **False sense of security**: Are people checking boxes without thinking? → Add verification. + +**Refinement strategies**: +- **Shorten**: Remove non-critical items. Aim for 5-9 items. +- **Reformat**: Switch READ-DO ↔ DO-CONFIRM based on user feedback. +- **Add forcing function**: Critical items become automated checks (not manual). +- **Add challenge-response**: Two-person verification for high-stakes items. + +--- + +## 6. Cognitive Biases and Mitigation + +### Availability Bias + +**Definition**: Judge frequency/probability by ease of recall. Recent, vivid events seem more common. + +**How it misleads heuristics**: +- Plane crash on news → Overestimate flight risk +- Recent fraud case → Overestimate fraud rate +- Salient failure → Avoid entire category + +**Mitigation**: +- Use base rates (statistical frequencies) not anecdotes +- Ask: "What's the actual data?" not "What do I remember?" +- Track all cases, not just memorable ones + +**Example**: +- Availability: "Customer from [Country X] didn't pay, avoid all [Country X] customers" +- Base rate check: "Only 2% of [Country X] customers defaulted vs. 1.5% overall" → Marginal difference, not categorical + +### Representativeness Bias + +**Definition**: Judge probability by similarity to stereotype/prototype. "Looks like X, therefore is X." + +**How it misleads heuristics**: +- "Looks like successful founder" (hoodie, Stanford, articulate) → Overestimate success +- "Looks like good engineer" (quiet, focused) → Miss great communicators + +**Mitigation**: +- Use objective criteria (track record, test scores) not stereotypes +- Check base rate: How often does stereotype actually predict outcome? +- Blind evaluation: Remove identifying information + +**Example**: +- Representativeness: "Candidate reminds me of [successful person], hire" +- Base rate: "Only 5% of hires succeed regardless of who they remind me of" + +### Anchoring Bias + +**Definition**: Over-rely on first piece of information. Initial number shapes estimate. + +**How it misleads heuristics**: +- First salary offer anchors negotiation +- Initial project estimate anchors timeline +- First price seen anchors value perception + +**Mitigation**: +- Set your own anchor first (make first offer) +- Deliberately adjust away from anchor (mental correction) +- Use external reference (market data, not internal anchor) + +**Example**: +- Anchoring: Candidate asks $150k, you offer $155k (anchored to their ask) +- Better: You offer $130k first (your anchor), negotiate from there + +### Confirmation Bias + +**Definition**: Seek, interpret, recall information confirming existing belief. Ignore disconfirming evidence. + +**How it misleads heuristics**: +- Heuristic works once → Notice only confirming cases +- Initial hypothesis → Search for supporting evidence only + +**Mitigation**: +- Actively seek disconfirming evidence ("Why might this heuristic fail?") +- Track all cases (not just successes) +- Pre-commit to decision rule, then test objectively + +**Example**: +- Confirmation: "Recognition heuristic worked on 3 cases!" (ignore 5 failures) +- Mitigation: Track all 50 cases → 25/50 = 50% accuracy (coin flip, abandon heuristic) + +### Sunk Cost Fallacy + +**Definition**: Continue based on past investment, not future value. "Already spent X, can't stop now." + +**How it misleads heuristics**: +- Heuristic worked in past → Keep using despite declining accuracy +- Spent time designing checklist → Force it to work despite low adoption + +**Mitigation**: +- Evaluate based on future value only ("Will this heuristic work going forward?") +- Pre-commit to abandonment criteria ("If accuracy <70%, switch methods") +- Ignore past effort when deciding + +**Example**: +- Sunk cost: "Spent 10 hours designing this heuristic, must use it" +- Rational: "Heuristic only 60% accurate, abandon and try different approach" + +--- + +## Advanced Topics + +### Swiss Cheese Model (Error Prevention) + +**James Reason's model**: Multiple defensive layers, each with holes. Error occurs when holes align. + +**Layers**: +1. Organizational (policies, culture) +2. Supervision (oversight, review) +3. Preconditions (fatigue, time pressure) +4. Actions (individual performance) + +**Checklist as defensive layer**: Catches errors that slip through other layers. + +**Example** (Deployment failure): +- Organizational: No deployment policy +- Supervision: No code review +- Preconditions: Friday night deployment (fatigue) +- Actions: Developer forgets migration +- **Checklist**: "☐ Database migration tested" catches error + +### Adaptive Heuristics + +**Concept**: Heuristic parameters adjust based on outcomes. + +**Example** (Satisficing with adaptive threshold): +- Start: Threshold = 80% of criteria +- After 10 searches, no options found → Lower to 70% +- After 5 options found → Raise to 85% + +**Implementation**: +``` +threshold = initial_threshold +search_count = 0 +options_found = 0 + +while not decided: + search_count += 1 + if option_meets_threshold: + options_found += 1 + decide(option) + + if search_count > K and options_found == 0: + threshold *= 0.9 # Lower threshold + if options_found > M: + threshold *= 1.1 # Raise threshold +``` + +### Context-Dependent Heuristics + +**Concept**: Different rules for different contexts. Meta-heuristic chooses which heuristic to use. + +**Example** (Decision approach): +1. **Check context**: + - Is decision reversible? Yes → Use fast heuristic (satisficing) + - Is decision irreversible? No → Use slow analysis (full evaluation) + +2. **Choose heuristic based on stakes**: + - <$1k: Recognition heuristic + - $1k-$10k: Satisficing + - >$10k: Full analysis + +**Implementation**: +``` +if stakes < 1000: + use recognition_heuristic() +elif stakes < 10000: + use satisficing(threshold=0.8) +else: + use full_analysis() +``` + +## Key Takeaways + +1. **Heuristics work in stable environments**: Recognition, take-the-best excel when patterns repeat. Fail in novel, adversarial contexts. + +2. **Satisficing beats optimization under uncertainty**: "Good enough" faster and often as good as perfect when environment unpredictable. + +3. **Checklists catch 60-80% of errors**: Proven in aviation, surgery, construction. Focus on killer items only (5-9 max). + +4. **READ-DO for novices, DO-CONFIRM for experts**: Match format to user. Forcing experts into READ-DO creates resistance. + +5. **Test heuristics empirically**: Don't assume rules work. Validate on ≥30 historical cases, target ≥80% accuracy. + +6. **Forcing functions > checklists for critical steps**: If step must be done, automate enforcement rather than relying on manual check. + +7. **Update heuristics when environment changes**: Rules optimized for past may fail when market shifts, tech disrupts, competition intensifies.

"What if gravity reversed?" is not useful counterfactual. Stay within bounds of plausibility given current knowledge. + +2. **Minimal rewrite principle** (counterfactuals): Change as little as possible. "What if we had chosen Y instead of X?" not "What if we had chosen Y and market doubled and competitor failed?" Isolate causal factor. + +3. **Avoid hindsight bias**: Pre-mortem assumes failure, but don't just list things that went wrong in similar past failures. Generate new failure modes specific to this context. + +4. **Specify mechanism**: Don't just state outcome ("sales would be higher"), explain HOW ("sales would be higher because lower price → higher conversion → more customers despite lower margin"). + +5. **Assign probabilities** (scenarios): Don't treat all scenarios as equally likely. Estimate rough probabilities (e.g., 60% baseline, 25% pessimistic, 15% optimistic). Avoids equal-weight fallacy. + +6. **Time horizon clarity**: Specify WHEN in future. "Product fails" is vague. "In 6 months, adoption <1000 users" is concrete. Enables tracking. + +7. **Extract actions, not just stories**: Scenarios are useless without implications. Always end with "so what should we do?" Prepare, hedge, pivot, or double-down. + +8. **Update scenarios**: Reality evolves. Quarterly review: which scenario is unfolding? Update probabilities and plans accordingly. + +**Common pitfalls:** + +- ❌ **Confusing counterfactual with fantasy**: "What if we had $100M funding from start?" vs. realistic "What if we had raised $2M seed instead of $1M?" +- ❌ **Too many scenarios**: 10 scenarios = analysis paralysis. Stick to 2-4 meaningful, distinct futures. +- ❌ **Scenarios too similar**: Three scenarios that differ only in magnitude (10% growth, 15% growth, 20% growth). Need qualitatively different worlds. +- ❌ **No causal mechanism**: "Sales would be 2× higher" without explaining why. Must specify how change leads to outcome. +- ❌ **Hindsight bias in pre-mortem**: Just listing past failures. Need to imagine new, context-specific risks. +- ❌ **Ignoring low-probability, high-impact**: "Black swan won't happen" until it does.

Counterfactual Reasoning + +### What Is Counterfactual Reasoning? + +Counterfactual reasoning asks: **"What would have happened if X had been different?"** It's a form of causal inference through imagined alternatives. + +**Core principle**: To understand causality, imagine the world with one factor changed and trace the consequences. + +**Example**: +- **Actual**: Startup raised $5M Series A → burned through runway in 14 months → failed to reach profitability +- **Counterfactual**: "What if we had raised $3M instead?" + - Hypothesis: Smaller team (8 vs 15 people), lower burn, forced focus on revenue, reached profitability in 12 months + - Reasoning: Constraint forces discipline. Without $5M runway, couldn't afford large team. Would prioritize revenue over growth. + - Insight: Raising more money enabled premature scaling. Constraint would have been beneficial. + +### The Minimal Rewrite Principle + +When constructing counterfactuals, change **as little as possible** to isolate the causal factor. + +**Bad counterfactual** (too many changes): +- "What if we had raised $3M AND competitor had failed AND market had doubled?" +- Problem: Can't tell which factor caused different outcome + +**Good counterfactual** (minimal change): +- "What if we had raised $3M (all else equal)?" +- Isolates the funding amount as causal variable + +**Technique**: Hold everything constant except the factor you're testing. This reveals whether that specific factor was causal. + +### Constructing Plausible Counterfactuals + +Not all "what ifs" are useful. Counterfactuals must be **plausible** given what was known/possible at the time. + +**Plausible**: "What if we had launched in EU first instead of US?" +- This was a real option available at decision time + +**Implausible**: "What if we had magically known the pandemic was coming?" +- Requires impossible foreknowledge + +**Test for plausibility**: Could a reasonable decision-maker have chosen this alternative given information available at the time? + +### Specifying Causal Mechanisms + +Don't just state outcome; explain **HOW** the change leads to different result. + +**Weak counterfactual**: "Sales would be 2× higher" +**Strong counterfactual**: "Sales would be 2× higher because lower price ($50 vs $100) → 3× higher conversion rate (15% vs 5%) → more customers despite 50% lower margin per customer → net revenue impact +2×" + +**Framework for causal chains**: +1. **Initial change**: What's different? (e.g., "Price is $50 instead of $100") +2. **Immediate effect**: What happens next? (e.g., "Conversion rate increases from 5% to 15%") +3. **Secondary effects**: What follows? (e.g., "Customer volume triples") +4. **Final outcome**: Net result? (e.g., "Revenue doubles despite lower margin") + +### Using Counterfactuals for Learning + +**Post-decision counterfactual analysis**: + +After a decision plays out, ask: +1. **What did we decide?** (Actual decision) +2. **What was the outcome?** (Actual result) +3. **What else could we have done?** (Alternative decision) +4. **What would have happened?** (Counterfactual outcome) +5. **What was the key causal factor?** (Insight for future) + +**Example**: Hired candidate A (strong technical, weak communication) → struggled, left after 6 months. Counterfactual: B (moderate technical, strong communication) would have stayed longer, collaborated better. **Insight**: For this role, communication > pure technical skill. + +### Avoiding Hindsight Bias + +**Hindsight bias**: "I knew it all along" — outcome seems inevitable after the fact. + +**Problem**: Makes counterfactual analysis distorted. "Of course it failed, we should have known." + +**Mitigation**: +- **Re-inhabit decision context**: What information was available then (not now)? +- **List alternatives considered**: What options were on the table at the time? +- **Acknowledge uncertainty**: How predictable was outcome given information available? + +**Technique**: Write counterfactual analysis in past tense but from perspective of decision-maker at the time, without benefit of hindsight. + +--- + +## 2. Scenario Planning Techniques + +### Three-Scenario Framework + +**Structure**: Optimistic, Baseline, Pessimistic futures + +**When to use**: General strategic planning, forecasting, resource allocation + +**Process**: + +1. **Define time horizon**: 6 months? 1 year? 3 years? 5 years? + - Shorter horizons: More specific, quantitative + - Longer horizons: More qualitative, exploratory + +2. **Identify key uncertainties**: What 2-3 factors most shape the future? + - Market adoption rate + - Competitive intensity + - Regulatory environment + - Technology maturity + - Economic conditions + +3. **Develop three scenarios**: + - **Optimistic** (15-30% probability): Best-case assumptions on key uncertainties + - **Baseline** (40-60% probability): Expected-case, extrapolating current trends + - **Pessimistic** (15-30% probability): Worst-case assumptions on key uncertainties + +4. **Describe each vividly**: Write 2-4 paragraph narrative making each world feel real + +5. **Extract implications**: What should we do in each scenario?

Users can filter by any combination. + +**Example**: Amazon product browse. Filter by Category AND Brand AND Price simultaneously.

Optimal: APIs (8 categories) → Authentication (6 methods) → jwt.sign() (3 clicks). + +### Pattern 5: Mental Model Alignment (Card Sorting) + +**When**: You don't know how users think about content + +**Process**: +1. **Open card sort**: Users create their own categories (exploratory) +2. **Closed card sort**: Users fit content into your categories (validation) +3. **Hybrid card sort**: Users use your categories OR create new ones (refinement) +4. **Analyze**: What labels do users use? What groupings emerge? What's confusing? + +**Example**: SaaS product features. Company calls them "Widgets", "Modules", "Components" (technical terms). Card sort reveals users think "Reports", "Dashboards", "Alerts" (task-based terms). **Insight**: Label by user tasks, not internal architecture. + +### Pattern 6: Tree Testing (Reverse Card Sort) + +**When**: Validating navigation structure before building + +**Process**: +1. **Create text-based tree** (sitemap without visuals) +2. **Give users tasks**: "Where would you find X?" +3. **Track paths**: What route did they take?

Identify duplicates, gaps, outdated items. Measure current performance (analytics, heatmaps). + +**Step 3: Conduct user research** ([details](#3-conduct-user-research)) +Run card sorting (open, closed, or hybrid) with 15-30 users.

Refine taxonomy based on data. + +--- + +## Critical Guardrails + +### 1. Test with Real Users, Not Assumptions + +**Danger**: Designing based on stakeholder opinions or personal preferences + +**Guardrail**: Always validate with user research (card sorting, tree testing, usability testing). Minimum 15 participants for statistical significance. + +**Red flag**: "I think users will understand 'Synergistic Solutions'..." — If you're guessing, you're wrong. + +### 2. Avoid Org Chart Navigation + +**Danger**: Structuring navigation by internal org structure (Sales, Marketing, Engineering) + +**Guardrail**: Structure by user mental models and tasks, not company departments + +**Example**: Bad: "About Us → Departments → Engineering → APIs". Good: "For Developers → APIs" + +### 3. Keep Navigation Shallow (3-4 Levels Max) + +**Danger**: Deep hierarchies (5+ levels) where users get lost + +**Guardrail**: Aim for 3-4 levels deep, 5-9 items per level. If deeper needed, add search, filtering, or multiple entry points. + +**Rule of thumb**: If users need >4 clicks from homepage to content, rethink structure. + +### 4. Use Clear, Specific Labels (Not Jargon) + +**Danger**: Vague labels ("Resources", "Solutions") or internal jargon ("SKU Management") + +**Guardrail**: Labels must be specific, action-oriented, and match user vocabulary. Test labels in card sorts and tree tests. + +**Test**: Could a new user predict what's under this label? If not, clarify. + +### 5. Ensure Single, Predictable Location + +**Danger**: Content lives in multiple places, or users can't predict location + +**Guardrail**: Each content type should have ONE canonical location. If cross-category, use clear primary location + links from secondary. + +**Principle**: "Principle of least astonishment" — content is where users expect it. + +### 6. Design for Scale + +**Danger**: Structure works for 50 items but breaks at 500 + +**Guardrail**: Think ahead. If you have 50 products now but expect 500, design faceted navigation from start. Don't force retrofitting later. + +**Test**: What happens if this category grows 10×? Will structure still work? + +### 7. Provide Multiple Access Paths + +**Danger**: Only one way to find content (e.g., only browse, no search) + +**Guardrail**: Offer browse (navigation), search, filters, related links, breadcrumbs, tags. Different users have different strategies. + +**Principle**: Some users are "searchers" (know what they want), others are "browsers" (exploring). Support both. + +### 8. Validate Before Building + +**Danger**: Building full site/app before testing structure + +**Guardrail**: Use tree testing (text-based navigation) to validate structure before expensive design/dev work + +**ROI**: 1 day of tree testing saves weeks of rework after launch. + +--- + +## Quick Reference + +### IA Methods Comparison + +| Method | When to Use | Participants | Deliverable | +|--------|-------------|--------------|-------------| +| **Open card sort** | Exploratory, unknown categories | 15-30 users | Category labels, groupings | +| **Closed card sort** | Validation of existing categories | 15-30 users | Fit quality, confusion points | +| **Tree testing** | Validate navigation structure | 20-50 users | Success rate, directness, problem areas | +| **Content audit** | Understand existing content | 1-2 analysts | Inventory spreadsheet, gaps, duplicates | +| **User interviews** | Understand mental models | 5-10 users | Mental model diagrams, quotes | + +### Navigation Depth Guidelines + +| Content Size | Recommended Structure | Example | +|--------------|----------------------|---------| +| <50 items | Flat (1-2 levels) | Blog, small product catalog | +| 50-500 items | Moderate (2-3 levels) | Documentation, medium e-commerce | +| 500-5000 items | Deep with facets (3-4 levels + filters) | Large e-commerce, knowledge base | +| 5000+ items | Hybrid (browse + search + facets) | Amazon, Wikipedia | + +### Labeling Systems + +| System | When to Use | Example | +|--------|-------------|---------| +| **Task-based** | Users have clear goals | "Book a Flight", "Track Order", "Pay Invoice" | +| **Audience-based** | Different user types | "For Students", "For Teachers", "For Parents" | +| **Topic-based** | Reference/learning content | "History", "Science", "Mathematics" | +| **Format-based** | Media libraries | "Videos", "PDFs", "Podcasts" | +| **Alphabetical** | No clear grouping, lookup-heavy | "A-Z Directory", "Glossary" | + +### Success Metrics + +| Metric | Target | Measurement | +|--------|--------|-------------| +| **Tree test success rate** | ≥70% | Users find correct destination | +| **Directness** | ≤1.5× optimal path | Clicks taken / optimal clicks | +| **Time to find** | <30 sec (simple), <2 min (complex) | Task completion time | +| **Search success** | ≥60% find without search | % completing task without search | +| **Bounce rate** | <40% | % leaving immediately from landing page | + +--- + +## Resources + +### Navigation to Resources + +- [**Templates**](resources/template.md): Content audit template, card sorting template, sitemap template, tree testing script +- [**Methodology**](resources/methodology.md): Card sorting analysis, taxonomy design, navigation patterns, findability optimization +- [**Rubric**](resources/evaluators/rubric_information_architecture.json): Evaluation criteria for IA quality (10 criteria) + +### Related Skills + +- **data-schema-knowledge-modeling**: For database schema and knowledge graphs +- **mapping-visualization-scaffolds**: For visualizing information structure +- **discovery-interviews-surveys**: For user research methods +- **evaluation-rubrics**: For creating IA evaluation criteria +- **communication-storytelling**: For explaining IA decisions to stakeholders + +--- + +## Examples in Context + +### Example 1: E-commerce Navigation Redesign + +**Context**: Bookstore with 10,000 books organized by publisher (internal logic) + +**Approach**: Content audit → Open card sort (20 users: genre-based, not publisher) → Faceted navigation: Genre × Format × Price × Rating → Tree test (75% success) → **Result**: Time to find -40%, conversion +15% + +### Example 2: SaaS Documentation IA + +**Context**: Developer docs, high abandonment after 2 pages + +**Approach**: User interviews (mental model = tasks not features) → Taxonomy shift: feature-based to task-based ("Get Started", "Store Data") → Progressive disclosure (hub-and-spoke) → Tree test (68% → 82% success) → **Result**: Engagement +50%, support tickets -25% + +### Example 3: Internal Knowledge Base + +**Context**: Company wiki with 2,000 articles, employees can't find policies + +**Approach**: Content audit (40% outdated, 15% duplicates) → Closed card sort (25 employees) → Hybrid: browse (known needs) + search (unknown) + metadata schema → Search best bets → **Result**: Search success 45% → 72%, time to find 5min → 1.5min diff --git a/skills/information-architecture/resources/evaluators/rubric_information_architecture.json b/skills/information-architecture/resources/evaluators/rubric_information_architecture.json new file mode 100644 index 0000000..5b55650 --- /dev/null +++ b/skills/information-architecture/resources/evaluators/rubric_information_architecture.json @@ -0,0 +1,211 @@ +{ + "criteria": [ + { + "name": "User Research Validation", + "description": "IA decisions based on user research (card sorting, tree testing, interviews), not assumptions or opinions.", + "scale": { + "1": "No user research.

Kill criteria remove emotion and politics from stopping decisions. + +--- + +## Common Patterns + +### Pattern 1: Upfront Kill Criteria (Before Launch) + +**When**: Starting new project, experiment, or product + +**Process**: (1) Define success metrics ("10% conversion"), (2) Set time horizon ("6 months"), (3) Establish kill criteria ("If <5% after 6 months, kill"), (4) Assign decision rights (specific person), (5) Document formally (signed PRD) + +**Example**: New feature — Success: 20% adoption in 3 months, Kill: <10% adoption, Decision: Product VP makes call + +### Pattern 2: Go/No-Go Gates (Milestone-Based) + +**When**: Multi-stage projects with increasing investment + +**Structure**: Stage 1 (cheap, concept) → Go/No-Go → Stage 2 (moderate, MVP) → Go/No-Go → Stage 3 (expensive, launch) → Go/No-Go + +**Example**: Gate 1 (4wk, $10k): 15+ customer interviews show interest → GO. Gate 2 (3mo, $50k): 40% weekly active (got 25%) → NO-GO, kill + +**Benefit**: Small investments first, kill before expensive stages + +### Pattern 3: Trigger-Based Exit Ramps + +**When**: Ongoing projects with uncertain outcomes + +**Common triggers**: Time-based ("not profitable by Month 18"), Metric-based ("churn >8% for 2 months"), Market-based ("competitor launches"), Resource-based ("budget overrun >30%"), Opportunity-based ("better option emerges") + +**Example**: SaaS — Trigger 1: MRR growth <10%/mo for 3 months → Evaluate. Trigger 2: CAC payback >24mo → Evaluate. Trigger 3: Competitor raises >$50M → Evaluate + +**Note**: Triggers prompt evaluation, not automatic kill + +### Pattern 4: Pivot vs. Kill Decision + +**When**: Project isn't working as planned — should you pivot or kill? + +**Framework**: + +**Pivot if**: +- Core insight is valid but execution is wrong +- Customer pain is real, solution is wrong +- Market exists, go-to-market is wrong +- Learning rate is high (discovering new insights rapidly) +- Resource burn is sustainable (not desperation mode) + +**Kill if**: +- No customer pain (nice-to-have, not must-have) +- Market too small (can't sustain business) +- Burn rate too high relative to progress +- Team doesn't believe in vision +- Better opportunities available (opportunity cost) +- Regulatory/legal blockers + +**Example**: Mobile app with low engagement +- **Situation**: Launched fitness app, 10k downloads, 5% weekly active (target was 40%) +- **Pivot option**: Interviews reveal users want meal tracking not workout tracking → Pivot to nutrition app +- **Kill option**: Users don't care about fitness tracking at all, market saturated → Kill, reallocate team + +**Decision**: Pivot if hypothesis valid but execution wrong. Kill if hypothesis invalid. + +### Pattern 5: Portfolio Kill Criteria (Multiple Projects) + +**When**: Managing portfolio of projects, need to kill some to focus + +**Process**: +1. **Rank by expected value**: ROI, strategic fit, resource efficiency +2. **Define minimum threshold**: "Top 70% of portfolio gets resources" +3. **Kill bottom 30%**: Projects below threshold, regardless of sunk cost +4. **Reallocate resources**: Winners get resources from killed projects + +**Example**: Company with 10 projects, capacity for 7 +- Rank by: (Expected Revenue × Probability of Success) / Resource Cost +- Kill: Projects ranked #8, #9, #10 (even if they're "almost done") +- Reallocate: Engineers from killed projects to top 3 + +**Principle**: Opportunity cost matters more than sunk cost. "Almost done" doesn't justify continuing if better alternatives exist. + +### Pattern 6: Sunk Cost Trap Avoidance + +**When**: Team resists killing project due to past investment + +**Technique**: **Pre-mortem inversion** +1. Ask: "If we were starting today with zero investment, would we start this project?" +2. If answer is "No" → Kill (sunk costs are irrelevant) +3. If answer is "Yes, but differently" → Pivot +4. If answer is "Yes, exactly as-is" → Continue + +**Example**: Failed enterprise sales push +- **Situation**: 18 months, $2M spent, 2 customers (need 50 for viability) +- **Inversion**: "If starting today, would we pursue enterprise sales?" → "No, we'd focus on self-serve SMB" +- **Decision**: Kill enterprise sales, pivot to SMB (sunk $2M is irrelevant) + +**Trap**: "We've invested so much, we can't quit now" → This is sunk cost fallacy +**Escape**: Only future costs and benefits matter. Past is gone. + +--- + +## Workflow + +Use this structured approach when defining or applying kill criteria: + +``` +□ Step 1: Define success metrics and time horizon +□ Step 2: Establish objective kill criteria +□ Step 3: Assign decision rights and governance +□ Step 4: Set milestone gates or trigger points +□ Step 5: Document formally (signed agreement) +□ Step 6: Monitor metrics regularly +□ Step 7: Evaluate at gates/triggers +□ Step 8: Execute kill decision (if triggered) +``` + +**Step 1: Define success metrics and time horizon** ([details](#1-define-success-metrics-and-time-horizon)) +Specify quantifiable success criteria (e.g., "20% conversion") and evaluation period (e.g., "6 months post-launch"). + +**Step 2: Establish objective kill criteria** ([details](#2-establish-objective-kill-criteria)) +Set numeric thresholds that trigger stop decision (e.g., "If <10% conversion after 6 months"). Make criteria objective, not subjective. + +**Step 3: Assign decision rights and governance** ([details](#3-assign-decision-rights-and-governance)) +Name specific person who makes kill decision. Define escalation process. Avoid "team consensus" (leads to paralysis). + +**Step 4: Set milestone gates or trigger points** ([details](#4-set-milestone-gates-or-trigger-points)) +For multi-stage projects: define go/no-go gates. For ongoing projects: define triggers that prompt evaluation. + +**Step 5: Document formally** ([details](#5-document-formally)) +Write kill criteria in PRD, project charter, or investment memo. Get stakeholders to sign/approve before launch (prevents moving goalposts). + +**Step 6: Monitor metrics regularly** ([details](#6-monitor-metrics-regularly)) +Track metrics weekly/monthly. Dashboard with kill criteria thresholds clearly marked. Automate alerts when approaching thresholds. + +**Step 7: Evaluate at gates/triggers** ([details](#7-evaluate-at-gatestriggers)) +When gate or trigger hit, conduct formal evaluation. Use pre-mortem inversion: "Would we start this today?" Decide: continue, pivot, or kill. + +**Step 8: Execute kill decision** ([details](#8-execute-kill-decision)) +If kill triggered: communicate decision, wind down project, reallocate resources, conduct postmortem. Execute quickly (avoid zombie projects). + +--- + +## Critical Guardrails + +### 1. Set Kill Criteria Before Launch (Not After) + +**Danger**: Defining kill criteria after project starts leads to moving goalposts + +**Guardrail**: Write kill criteria in initial project document, before emotional/financial investment. Get stakeholder sign-off. + +**Red flag**: "We'll figure out when to stop as we go" — this leads to sunk cost trap + +### 2. Make Criteria Objective (Not Subjective) + +**Danger**: Subjective criteria ("team feels it's not working") are easy to ignore + +**Guardrail**: Use quantifiable metrics (numbers, dates, milestones). "5% conversion" not "low adoption". "6 months" not "reasonable time". + +**Test**: Could two people independently evaluate criteria and reach same conclusion? If not, too subjective. + +### 3. Assign Clear Decision Rights + +**Danger**: "Team decides" or "we'll discuss" leads to paralysis (everyone has sunk cost) + +**Guardrail**: Name specific person who makes kill decision. Define what data they need. Escalation path for overrides. + +**Example**: "Product VP makes kill decision based on 6-month metrics. Can be overridden only by CEO with written justification." + +### 4. Don't Move the Goalposts + +**Danger**: When kill criteria approached, team lowers bar or extends timeline + +**Guardrail**: Kill criteria are fixed at launch. Changes require formal process (written justification, senior approval, new document). + +**Red flag**: "Let's give it another 3 months" when 6-month criteria not met + +### 5. Sunk Costs Are Irrelevant + +**Danger**: "We've invested $2M, can't stop now" — sunk cost fallacy + +**Guardrail**: Use pre-mortem inversion: "If starting today with $0 invested, would we do this?" Only future matters. + +**Principle**: Past costs are gone. Only question: "Is future investment better here or elsewhere?" + +### 6. Kill Quickly (Avoid Zombie Projects) + +**Danger**: Projects that should be killed linger, draining resources ("zombie projects") + +**Guardrail**: Kill decision → immediate wind-down. Announce within 1 week, reallocate team within 1 month. + +**Red flag**: Project in "wind-down" for >3 months — this is zombie mode, not killing + +### 7. Opportunity Cost > Sunk Cost + +**Danger**: Continuing project because "almost done" even if better opportunities exist + +**Guardrail**: Portfolio thinking. Ask: "Is this the best use of these resources?" If not, kill even if 90% done. + +**Principle**: Opportunity cost of *not* pursuing better option often exceeds benefit of finishing current project + +### 8. Postmortem, Don't Blame + +**Danger**: Kill decisions seen as "failure", teams avoid them + +**Guardrail**: Normalize killing projects. Celebrate disciplined stopping. Postmortem focuses on learning, not blame. + +**Culture**: "We killed 3 projects this quarter" = good (freed resources for winners), not bad (failures) + +--- + +## Quick Reference + +### Kill Criteria Checklist + +Before launching project, answer: +- [ ] Success metrics defined?

Advanced Topics + +### Real Options Theory + +**Concept**: Treat uncertain projects as financial options + +**Option types**: +1. **Option to defer**: Delay investment until uncertainty resolves +2. **Option to expand**: Scale up if initial results positive +3. **Option to contract**: Scale down if results negative +4. **Option to abandon**: Kill if results very negative +5. **Option to switch**: Pivot to alternative use + +**Valuation**: Black-Scholes model adapted for projects +- **Underlying asset**: NPV of project +- **Strike price**: Investment required +- **Volatility**: Uncertainty in outcomes +- **Time to expiration**: Decision window + +**Application**: Continue projects with high option value (high upside, limited downside, flexibility) + +### Stage-Gate Process Design + +**Optimal gate structure**: +- **3-5 gates** for major initiatives +- **Investment increases** by 3-5× at each gate (e.g., $10k → $50k → $200k → $1M) +- **Success criteria tighten** at each gate (higher bar as investment grows) + +**Gate design**: +- **Gate 0 (Concept)**: $0-10k, 1-2 weeks, validate problem exists +- **Gate 1 (Discovery)**: $10-50k, 4-8 weeks, validate solution direction +- **Gate 2 (MVP)**: $50-200k, 2-3 months, validate product-market fit +- **Gate 3 (Scale)**: $200k-1M, 6-12 months, validate unit economics +- **Gate 4 (Growth)**: $1M+, ongoing, optimize and scale + +**Kill rates by gate** (typical): +- Gate 0 → 1: Kill 50% (cheap to kill, many bad ideas) +- Gate 1 → 2: Kill 30% (learning reveals issues) +- Gate 2 → 3: Kill 20% (product-market fit hard) +- Gate 3 → 4: Kill 10% (unit economics don't work) + +### Bayesian Updating for Kill Criteria + +**Process**: Update kill probability as new data arrives + +**Steps**: +1. **Prior probability** of kill: P(Kill) = initial estimate (e.g., 40% based on historical kill rate) +2. **Likelihood** of data given kill: P(Data | Kill) = how likely is this data if project should be killed? +3. **Likelihood** of data given success: P(Data | Success) = how likely is this data if project will succeed? +4. **Posterior probability** using Bayes theorem: P(Kill | Data) = P(Data | Kill) × P(Kill) / P(Data) + +**Example**: SaaS feature with 10% adoption target (kill if <10% after 6 months) +- **Month 3 data**: 7% adoption +- **Prior**: P(Kill) = 40% (4 in 10 similar features killed historically) +- **Likelihood**: P(7% at month 3 | Kill) = 70% (projects that get killed typically have ~7% at halfway point) +- **Likelihood**: P(7% at month 3 | Success) = 30% (successful projects typically have ~12% at halfway point) +- **Posterior**: P(Kill | 7% adoption) = (0.70 × 0.40) / [(0.70 × 0.40) + (0.30 × 0.60)] = 0.28 / 0.46 = 61% +- **Interpretation**: 61% chance this project should be killed (up from 40% prior) +- **Action**: Evaluate closely, prepare pivot/kill plan + +### Stopping Rules in Scientific Research + +**Clinical trial stopping rules** (adapted for product development): + +1. **Futility stopping**: Stop early if interim data shows unlikely to reach success criteria + - **Rule**: If <10% chance of reaching target at current trajectory → Stop + - **Application**: Monitor weekly, project trajectory, stop if trajectory misses by >30% + +2. **Efficacy stopping**: Stop early if interim data shows clear success (reallocate resources) + - **Rule**: If >95% confident success criteria will be met → Graduate early + - **Application**: Feature with 25% adoption at month 3 (target: 15% at month 6) → Graduate to core product + +3. **Safety stopping**: Stop if harmful unintended consequences detected + - **Rule**: If churn increases >20% or NPS drops >10 points → Stop immediately + - **Application**: New feature causing user confusion, support ticket spike → Kill + +**Example**: Mobile app experiment +- **Target**: 20% weekly active users at month 6 +- **Month 2 data**: 5% weekly active +- **Trajectory**: Projecting 10% at month 6 (50% below target) +- **Futility analysis**: 95% confidence interval for month 6: 8-12% (entirely below 20% target) +- **Decision**: Invoke futility stopping, kill experiment at month 2 (save 4 months) + +--- + +## Key Principles Summary + +1. **Set kill criteria before launch** (remove emotion, politics, sunk cost bias) +2. **Make criteria objective** (numbers, dates, not feelings) +3. **Assign clear decision rights** (single decision-maker, not committee) +4. **Don't move goalposts** (criteria are fixed; changes require formal process) +5. **Sunk costs are irrelevant** (only future value matters) +6. **Kill quickly** (wind down within 1 month, avoid zombie projects) +7. **Opportunity cost > sunk cost** (kill even if "almost done" if better options exist) +8. **Normalize killing** (celebrate discipline, share learnings, remove stigma) +9. **Portfolio thinking** (rank all projects, kill bottom 20-30% regularly) +10. **Learn from kills** (blameless postmortems, apply insights to future projects) + +--- + +## Common Mistakes and Solutions + +| Mistake | Symptom | Solution | +|---------|---------|----------| +| **Setting criteria after launch** | Goalposts move when results disappoint | Document criteria in PRD before launch, get sign-off | +| **Subjective criteria** | Debate over "low engagement" | Quantify: "<10% weekly active", not "poor adoption" | +| **Team consensus for kill** | Paralysis, no one wants to kill | Single decision-maker with clear authority | +| **Sunk cost justification** | "Invested $2M, can't quit" | Pre-mortem inversion: "Would we start this today?" | +| **Zombie projects** | Lingering for 6+ months | Wind down within 1 month of kill decision | +| **Stigma around killing** | Teams hide struggles, delay kill | Celebrate kills, share postmortems, normalize stopping | +| **Portfolio inertia** | Same projects year over year | Quarterly ranking + kill bottom 20-30% | +| **No postmortem** | Repeat same mistakes | Require postmortem within 2 weeks,

Makes assumptions visible and aids future iteration. + +--- + +## Critical Guardrails + +### 1. Maintain Consistency Across Layers + +**Danger**: Strategic goals contradict operational reality, or implementation violates principles + +**Guardrail**: Regularly check upward, downward, and lateral consistency. Propagate changes bidirectionally (strategy changes → update tactics/ops; operational constraints → update tactics/strategy). + +**Red flag**: "Our strategy is X but we actually do Y" signals layer mismatch + +### 2. Don't Skip Layers When Communicating + +**Danger**: Jumping from 30K to 300 ft confuses audiences, loses context + +**Guardrail**: Move through layers sequentially. If explaining to executive, start 30K → 3K (stop there unless asked). If explaining to engineer, provide 30K context first, then dive to 300 ft. + +**Test**: Can listener answer "why does this matter?" (links to upper layer) and "how do we do this?" (links to lower layer) + +### 3. Each Layer Should Be Independently Useful + +**Danger**: Layers that only make sense when combined, not standalone + +**Guardrail**: Strategic layer should guide decisions even without seeing operations. Tactical layer should be understandable without code. Operational layer should be executable without re-deriving strategy. + +**Principle**: Good layers can be consumed independently by different audiences + +### 4. Limit Layers to 3-5 Levels + +**Danger**: Too many layers create overhead; too few lose nuance + +**Guardrail**: For most domains, 3 layers sufficient (strategy/tactics/operations or architecture/design/code). Complex domains may need 4-5 but rarely more. + +**Rule of thumb**: Can you name each layer clearly? If not, you have too many. + +### 5. Upper Layers Constrain, Lower Layers Implement + +**Danger**: Treating layers as independent rather than hierarchical + +**Guardrail**: Strategic layer sets constraints ("must be HIPAA compliant"). Tactical layer chooses approaches within constraints ("encryption + audit logs"). Operational layer implements ("AES-256 + CloudTrail"). Cannot violate upward. + +**Anti-pattern**: Operational decision ("skip encryption for speed") violating strategic constraint ("HIPAA compliance") + +### 6. Propagate Changes Bidirectionally + +**Danger**: Strategic shift without updating tactics/ops, or operational constraint discovered but strategy unchanged + +**Guardrail**: **Top-down**: Strategy changes → re-evaluate tactics → adjust operations. **Bottom-up**: Operational constraint → re-evaluate tactics → potentially adjust strategy. + +**Example**: Strategy shift to "privacy-first" → Update tactics (end-to-end encryption) → Update ops (implement encryption). Or: Operational constraint (performance) → Tactical adjustment (different approach) → Strategic clarification ("privacy-first within performance constraints") + +### 7. Make Assumptions Explicit at Each Layer + +**Danger**: Implicit assumptions lead to inconsistency when assumptions violated + +**Guardrail**: Document assumptions at each layer. Strategic: "Assuming competitive market." Tactical: "Assuming cloud infrastructure." Operational: "Assuming Python 3.9+." + +**Benefit**: When assumptions change, know which layers need updating + +### 8. Recognize Emergent Properties + +**Danger**: Focusing only on designed properties, missing unintended consequences + +**Guardrail**: Regularly observe bottom layer, look for emerging patterns at middle layer, consider strategic implications. Emergent properties can invalidate strategic assumptions. + +**Example**: Microservices (operational) → Coordination overhead (tactical emergence) → Slower feature delivery (strategic failure if goal was speed) + +--- + +## Quick Reference + +### Layer Mapping by Domain + +| Domain | Layer 1 (30K ft) | Layer 2 (3K ft) | Layer 3 (300 ft) | +|--------|------------------|-----------------|------------------| +| **Business** | Vision, mission | Strategy, objectives | Tactics, tasks | +| **Product** | Market positioning | Feature roadmap | User stories | +| **Technical** | Architecture principles | System design | Code implementation | +| **Organizational** | Culture, values | Policies, processes | Daily procedures | + +### Consistency Check Questions + +| Check Type | Question | +|------------|----------| +| **Upward** | Do these operations implement the tactics?

Do 70% predictions happen 70%? + +### Ignoring Variance +**What:** Judging strategy on <30 trials. Example: "Down 15% after 20 bets, strategy sucks" (normal variance). +**Fix:** Require 50+ bets minimum, 100+ preferred, 200+ for high confidence. + +### Outcome Bias +**What:** Judging by results not process. +15% EV lost = good decision (bad outcome). -10% EV won = bad decision (lucky). +**Fix:** Checklist: EV correct? Edge > threshold? Kelly fraction? Followed system?

Proper Scoring Rules + +### What is a Scoring Rule? + +A **scoring rule** assigns a numerical score to a probabilistic forecast based on the forecast and actual outcome. + +**Purpose:** Measure accuracy, incentivize honesty, enable comparison, track calibration over time. + +### Strictly Proper vs Quasi-Proper + +**Strictly Proper:** Reporting your true belief uniquely maximizes your expected score. No other probability gives better expected score. + +**Why it matters:** Incentivizes honesty, eliminates gaming, optimizes for accurate beliefs. + +**Quasi-Proper:** True belief maximizes score, but other probabilities might tie. Less desirable for forecasting. + +### Common Proper Scoring Rules + +**1. Brier Score** (strictly proper) +``` +Score = -(p - o)² +p = Your probability (0 to 1) +o = Outcome (0 or 1) +``` + +**2. Logarithmic Score** (strictly proper) +``` +Score = log(p) if outcome occurs +Score = log(1-p) if outcome doesn't occur +``` + +**3.

Sharpness + +### What is Sharpness? + +**Sharpness** = Tendency to make extreme predictions (away from 50%) when appropriate. + +**Sharp:** Predicts 5% or 95% when evidence supports it (decisive) + +**Unsharp:** Stays near 50% (plays it safe, indecisive) + +### Why Sharpness Matters + +``` +Scenario: Base rate 60% + +Unsharp forecaster: 50% for every event → Brier: 0.24, Usefulness: Low +Sharp forecaster: Range 20-90% → Brier: 0.12 (if calibrated), Usefulness: High +``` + +**Insight:** Extreme predictions (when accurate) improve Brier significantly. When wrong, hurt badly.

(Anki algorithm or similar) +- Retire cards after 5+ successful recalls +- Add mnemonic devices for difficult items +- Use: Anatomy, geography, historical dates, pharmacology + +## Guardrails + +**Avoid Common Mistakes:** +- ❌ Passive re-reading or highlighting → Use active retrieval instead +- ❌ Cramming (massed practice) → Use spaced repetition +- ❌ Blocking by topic (all topic A, then all topic B) → Use interleaving +- ❌ Over-confidence after initial learning → Test yourself repeatedly +- ❌ No tracking → Measure retention to adjust schedule + +**Realistic Expectations:** +- Forgetting is normal and necessary for strong memory consolidation +- Initial struggles with retrieval are productive ("desirable difficulties") +- Expect 20-40% forgetting between reviews (that's the sweet spot) +- Spaced repetition feels less productive than massing, but works better +- Plan for 2-3x more time than you think you need + +**Time Management:** +- Daily consistency > marathon sessions +- Minimum 15-20 min/day more effective than 2 hours weekly +- Peak retention: 25 min study → 5 min break → repeat +- Review sessions should be shorter than initial learning sessions +- Build buffer for life interruptions (illness, travel, deadlines) + +**When to Seek Help:** +- Material isn't making sense after 3+ attempts → Get instructor/expert help +- Retention remains below 60% after 3 review

ARIZ Algorithm + +### Concept +ARIZ (Algorithm of Inventive Problem Solving) is systematic step-by-step process for complex problems where contradiction isn't obvious. + +### ARIZ Steps (Simplified) + +**Step 1: Problem Formulation** +- State problem as given +- Identify ultimate goal +- List available resources (time, space, substances, fields, information) + +**Step 2: Mini-Problem** +- Define "ideal final result" (IFR): system achieves goal with minimal change +- Formulate mini-problem: "Element X, using available resources, must provide [desired effect] without [harmful effect]" + +**Step 3: Physical Contradiction** +- Identify conflicting requirements on single element +- Example: "Element must be hard (for strength) AND soft (for flexibility)" + +**Step 4: Separate Contradictions** +Four separation principles: +- **In space:** Hard in one location, soft in another +- **In time:** Hard during use, soft during installation +- **Upon condition:** Hard under load, soft when relaxed +- **Between system levels:** Hard at macro level, soft at micro level + +**Step 5: Application of Resources** +- What substances are available? (in system, nearby, environment, products/derivatives) +- What fields are available? (waste heat, vibration, gravity, pressure) +- How can cheap/free resources substitute for expensive ones? + +**Step 6: Apply Substance-Field Model** +- Model current state +- Identify incomplete or harmful models +- Apply standard solutions + +**Step 7: Apply TRIZ Principles** +- If not solved yet, use contradiction matrix +- Try 2-3 most relevant principles + +**Step 8: Analyze Solution** +- Does it achieve IFR? +- What new problems arise? +- Can solution be generalized to other domains? + +### ARIZ Example (Abbreviated) + +**Problem:** Bike lock must be strong (resist cutting) but lightweight (portable) + +**Step 1:** Goal = secure bike, Resources = lock material, bike frame, environment + +**Step 2:** IFR = Lock secures bike without added weight. Mini-problem: Lock, using available resources, must resist cutting without being heavy. + +**Step 3:** Physical contradiction - Lock material must be thick/strong (resist cutting) AND thin/light (reduce weight) + +**Step 4:** Separation - In space (strong in critical area only), Upon condition (hard when attacked, normal otherwise) + +**Step 5:** Resources - Can we use bike frame itself? Environment (anchor to heavy object)? + +**Step 6:** Substance-field - Add alarm field (makes cutting detectable even if lock is light) + +**Step 7:** TRIZ - Principle #40 (composite materials): Use hardened steel inserts in lightweight frame. Principle #2 (taking out): Secure bike to immovable object, lock just prevents separation. + +**Step 8:** Solution - Lightweight cable with selective hardening + alarm. Achieves security without excessive weight. + +--- + +## 4. Combining Morphological Analysis + TRIZ + +### When to Combine + +**Use case:** Complex system with multiple parameters (morphological) AND contradictions within configurations (TRIZ) + +### Process + +**Step 1:** Build morphological box for overall system architecture + +**Step 2:** Identify promising parameter combinations (3-5 configurations) + +**Step 3:** For each configuration, identify embedded contradictions +- Does this configuration create any trade-offs? +- Which parameters conflict within this configuration? + +**Step 4:** Apply TRIZ to resolve contradictions within each configuration +- Use TRIZ principles to eliminate trade-offs +- Improve configurations to be non-compromise solutions + +**Step 5:** Re-evaluate configurations now that contradictions are resolved +- Configurations that were inferior due to contradictions may now be viable + +### Example: Designing Portable Speaker + +**Morphological Parameters:** +- Power: Battery | Solar | Wall plug | Hybrid +- Size: Pocket | Handheld | Tabletop | Floor +- Audio tech: Mono | Stereo | Surround | Spatial +- Material: Plastic | Metal | Wood | Fabric +- Price tier: Budget | Mid | Premium | Luxury + +**Configuration 1: Pocket + Battery + Stereo + Plastic + Mid** +- Contradiction: Pocket size (small) vs Stereo (needs speaker separation for stereo imaging) +- TRIZ Solution: Principle #17 (another dimension) - Use beamforming or psychoacoustic processing to create virtual stereo from single driver + +**Configuration 2: Tabletop + Solar + Surround + Wood + Premium** +- Contradiction: Solar (needs light, outdoor) vs Wood (damages in weather) +- TRIZ Solution: Principle #30 (flexible shell) - Protective cover deploys when outdoors, retracts indoors + +**Outcome:** Both configurations now viable without compromises + +--- + +## 5. Multi-Contradiction Problems + +### Challenge +Real systems often have multiple contradictions that interact. + +### Approach + +**Step 1: Map all contradictions** +``` +Contradiction 1: Improve A → worsens B +Contradiction 2: Improve C → worsens D +Contradiction 3: Improve A → worsens D +... +``` + +**Step 2: Identify primary contradiction** +- Which contradiction, if resolved, eliminates or eases others? +- Which contradiction is most critical to success? + +**Step 3: Resolve primary contradiction first** +- Apply TRIZ principles +- Generate solution concepts + +**Step 4: Check if resolving primary affects secondary contradictions** +- Did solution eliminate secondary contradictions? +- Did solution worsen secondary contradictions? + +**Step 5: Resolve remaining contradictions** +- Apply TRIZ to each remaining contradiction +- Check for conflicts between solutions + +**Step 6: Integrate solutions** +- Can multiple TRIZ principles be combined? +- Are there synergies between solutions? + +### Example: Electric Vehicle Design + +**Contradictions:** +1. Improve range → worsens cost (large battery expensive) +2. Improve acceleration → worsens range (high power drains battery) +3. Improve safety → worsens weight (reinforcement adds mass) +4. Reduce weight → worsens safety (less structure) + +**Primary:** Range vs Cost (most critical for market adoption) + +**TRIZ Solutions:** +- Principle #6 (universality): Battery also serves as structural element (improves range without added weight/cost) +- Principle #35 (parameter change): Use different battery chemistry (higher energy density) + +**Secondary contradictions affected:** +- Weight reduced (battery is structure) → helps safety-weight contradiction +- Can now afford stronger materials with weight/cost savings + +**Integrated solution:** Structural battery pack with high energy density cells + +--- + +## 6.

Principled Negotiation (Harvard Method) + +### Concept +Separate people from problem, focus on interests not positions, generate options for mutual gain, and use objective criteria. + +### Four Principles + +**1. Separate People from Problem:** Attack problem, not people. Use "I feel..." not "You always...". Frame as joint problem-solving. + +**2. Focus on Interests, Not Positions:** Positions = what they want. Interests = why they want it. Ask "Why?" to uncover underlying needs. Interests are negotiable, positions often aren't. + +**3. Generate Options for Mutual Gain:** Brainstorm without committing. Look for low-cost-to-give, high-value-to-receive trades. Bundle issues across dimensions. Consider phased approaches. + +**4. Insist on Objective Criteria:** Use fair standards (market rates, benchmarks, precedent, technical data) instead of arguing positions. Propose criteria before solutions. + +### Application + +**Prepare:** Identify interests (yours/theirs), develop BATNA, research criteria. +**Explore:** Build rapport, listen for interests, share yours, ask why. +**Generate:** Brainstorm options, build on ideas, find mutual gains. +**Decide:** Evaluate against criteria, discuss trade-offs, package deal, document. + +--- + +## 2. BATNA & ZOPA Analysis + +### Concept +**BATNA:** Best Alternative To Negotiated Agreement—what you'll do if negotiation fails +**ZOPA:** Zone of Possible Agreement—range where both parties are better off than BATNA + +### Developing BATNA + +**Steps:** +1. List alternatives if negotiation fails +2. Evaluate each alternative's value +3. Select best alternative (your BATNA) +4. Calculate reservation price (minimum acceptable) + +**Example:** BATNA = hire next-best candidate for $120K. Reservation for top candidate: $150K. + +### Estimating Their BATNA + +Research alternatives, ask what they'll do if no deal, observe eagerness. Strong BATNA = harder to negotiate. + +### ZOPA (Zone of Possible Agreement) + +Exists when your reservation > their reservation. Any price in ZOPA works. No ZOPA = no deal possible. + +**Improve Position:** +- Strengthen your BATNA (more/better alternatives) +- Weaken their BATNA (reduce their options) +- Expand ZOPA (add value, reduce costs) + +**Walk away when:** Offer worse than BATNA, bad faith negotiation, cost exceeds gain. + +--- + +## 3. Stakeholder Power-Interest Mapping + +### Concept +Map stakeholders on two dimensions: Power (influence on decision) and Interest (care about outcome). + +### Power-Interest Matrix + +**High Power, High Interest:** Manage Closely (engage deeply, collaborate, veto/approval rights) +**High Power, Low Interest:** Keep Satisfied (prevent blocking, don't over-engage) +**Low Power, High Interest:** Keep Informed (updates, gather input, build support) +**Low Power, Low Interest:** Monitor (minimal engagement, check periodically) + +### Mapping Process + +1. Identify stakeholders (affected, authority, can block, expertise) +2. Assess power (1-5): formal authority, informal influence, resource control +3. Assess interest (1-5): how much outcome matters, energy invested +4. Plot on matrix and identify quadrant +5. Plan engagement per quadrant + +### Stakeholder Analysis + +For each key stakeholder: Identify interests/concerns/constraints, position (support/oppose/neutral), influence patterns, engagement plan (frequency, format, needs). + +### Coalition Building + +**When:** Multiple approvals needed, overcome opposition, shared ownership +**How:** Identify allies, start 1:1, frame as their interest, formalize at critical mass +**Types:** Blocking (prevent), Sponsoring (drive), Advisory (legitimacy) + +--- + +## 4. Advanced Governance Patterns + +### Pattern 1: Federated Governance + +**Use Case:** Balance central standards with local autonomy + +**Structure:** +- **Center:** Sets minimum viable standards, provides shared services +- **Edges:** Freedom to exceed standards, adapt to local needs +- **Escalation:** Center reviews exceptions, adjusts standards over time + +**Example (Engineering):** +- Center: Security standards, deployment pipeline, observability +- Edges: Language choice, frameworks, architecture patterns +- Review: Quarterly tech radar updates standards based on edge innovations + +**Governance:** +- Central: DACI for standards (Approver = Architecture board) +- Local: DACI for implementations (Approver = Tech lead) +- Escalation: RFC process for proposed standard changes + +### Pattern 2: Rotating Leadership + +**Use Case:** Shared ownership across teams, avoid permanent power concentration + +**Structure:** +- Leadership role rotates (monthly, quarterly) +- Role has decision authority while held +- Handoff includes documentation and context + +**Example (On-call):** +- Weekly on-call rotation +- On-call engineer has authority to escalate, roll back, make emergency decisions +- Handoff includes incident summaries, ongoing issues + +**Governance:** +- Clear scope of rotating role authority +- Fallback to permanent leadership if needed +- Retrospective to improve rotation + +### Pattern 3: Bounded Delegation + +**Use Case:** Empower teams while maintaining guardrails + +**Structure:** +- Define "decision boundary" with constraints +- Within boundary: Team decides (advice process) +- Outside boundary: Escalate for approval + +**Example (Budget):** +- Team has $50K discretionary budget +- Under $50K: Team decides after advice process +- Over $50K: Requires VP approval with business case + +**Governance:** +- Document boundary explicitly (what's in/out) +- Review boundary periodically (expand as trust grows) +- Escalation for gray areas + +### Pattern 4: Tiered Decision Rights + +**Use Case:** Different decision speeds for different risk levels + +**Structure:** +- **Tier 1 (Fast/Reversible):** Consent (no objections), execute quickly +- **Tier 2 (Medium/Partially Reversible):** DACI with light analysis +- **Tier 3 (Slow/Irreversible):** DACI with deep analysis, executive approval + +**Example (Product):** +- **Tier 1:** UI copy changes, feature flag toggles, A/B test parameters +- **Tier 2:** New features (reversible via flag), pricing experiments +- **Tier 3:** Sunsetting products, changing business model, major integrations + +**Governance:** +- Define criteria for each tier (reversibility, cost, customer impact) +- Different approval workflows per tier +- Review tier assignments quarterly + +### Pattern 5: Dual Authority (Checks & Balances) + +**Use Case:** Decisions requiring both opportunity and risk perspective + +**Structure:** +- **Proposer:** Recommends decision (opportunity focus) +- **Reviewer:** Veto power (risk focus) +- Both must agree to proceed + +**Example (Product Launch):** +- **Product (Proposer):** Decides what to build, when to launch +- **Engineering (Reviewer):** Veto on quality/security/technical risk +- Must both agree to ship + +**Governance:** +- Proposer has default authority (bias toward action) +- Reviewer can block but must explain objection +- Escalation if persistent disagreement +- Avoid making reviewer "decider" (creates bottleneck) + +--- + +## 5. Conflict Mediation Techniques + +### Technique 1: Active Listening + +**Purpose:** Ensure each party feels heard before problem-solving + +**Process:** +1. **Listen without interrupting:** Let speaker finish completely +2. **Paraphrase:** "What I hear you saying is..." +3. **Validate emotion:** "I can see why you'd feel frustrated about..." +4. **Clarify:** "Can you help me understand...?" +5. **Check understanding:** "Did I capture that correctly?" + +**Mediator Role:** +- Enforce turn-taking (no interruptions) +- Paraphrase to ensure understanding +- Separate facts from interpretations +- Acknowledge emotions without judgment + +### Technique 2: Interest-Based Problem Solving + +**Process:** +1. **State the Problem:** Frame as shared challenge +2. **Identify Interests:** Each party shares underlying needs +3. **Generate Options:** Brainstorm without evaluating +4. **Evaluate Options:** Test against both parties' interests +5. **Select Solution:** Choose best option, document agreement + +**Facilitator Moves:** +- Ask "Why?" to surface interests +- Prevent position-arguing +- Encourage creative options +- Use objective criteria for evaluation + +### Technique 3: Reframing + +**Purpose:** Shift perspective to enable resolution + +**Common Reframes:** +- **From blame to shared problem:** "Instead of whose fault, let's solve it together" +- **From positions to interests:** "You both want [shared interest], just different paths" +- **From past to future:** "We can't change what happened; let's prevent recurrence" +- **From personal to structural:** "The issue is the process, not the people" + +**Examples:** +- ❌ "You always ignore security" → ✓ "How can we integrate security earlier?" +- ❌ "You're blocking progress" → ✓ "You're raising important risks we should address" +- ❌ "This failed because of X" → ✓ "What can we learn to improve next time?" + +### Technique 4: Finding Common Ground + +**Purpose:** Build on agreement before tackling disagreement + +**Process:** +1. **Areas of Agreement:** What do both parties agree on? +2. **Shared Goals:** What outcome do both want? +3. **Complementary Needs:** Where do needs not conflict? +4. **Mutual Interests:** What benefits both? + +**Example:** +- **Agree:** Both want product to succeed +- **Agree:** Both care about customer satisfaction +- **Disagree:** Timeline and scope +- **Reframe:** "Given we both want customer satisfaction, how do we balance speed and quality?" + +### Technique 5: Caucusing (Separate Meetings) + +**When to Use:** +- Emotions too high for joint session +- Need to explore options privately +- Build trust with mediator individually +- Develop proposals before joint discussion + +**Process:** +1. Meet separately with each party +2. Understand their perspective, interests, constraints +3. Test potential solutions privately +4. Build trust and rapport +5. Bring parties together with prepared proposals + +**Mediator Confidentiality:** +- Clarify what can be shared vs private +- Don't carry messages blindly +- Use caucus to prepare for productive joint session + +--- + +## 6.

Individual reflection (1 min) +2. Pair discussion (2 min) +3. Quartet discussion (4 min) +4. Full group share out + +**Silent Writing:** +- All write ideas on sticky notes simultaneously +- Share by reading aloud or clustering +- Prevents groupthink, amplifies quiet voices + +### Pattern 2: Decision-Making Methods + +**Consent (Fast):** +- Propose solution +- Ask: "Any objections?" +- If none: Adopt +- If objections: Modify to address + +**Fist-to-Five (Quick Poll):** +- 0 fingers: Block (have alternative) +- 1-2: Concerns (need to discuss) +- 3: Accept (neutral) +- 4-5: Support (will champion) + +**Dot Voting (Prioritization):** +- List options +- Each person gets N dots +- Place dots on preferences +- Tally for ranking + +**Gradient of Agreement:** +1. Wholehearted endorsement +2. Agreement with minor reservations +3. Support with reservations +4. Abstain (can live with it) +5. More discussion needed +6. Disagree but will support +7. Serious disagreement + +### Pattern 3: Time Management + +**Timeboxing:** +- Set fixed time for each agenda item +- Visible timer +- "Parking lot" for tangents +- Decide: More time or move on? + +**Decision Point Protocol:** +- State decision needed +- Clarify options +- Time-boxed discussion +- Decision method (consent, vote, etc.) +- Document and move on + +**Escalation Trigger:** +- If no decision after N discussions: Escalate +- Prepare escalation: Options, analysis, recommendation +- Escalate to: [Specified decider] + +--- + +## 7. Multi-Party Negotiation + +### Challenge +More parties = exponentially more complexity (preferences, coalitions, communication) + +### Strategy 1: Bilateral Then Multilateral + +**Process:** +1. Negotiate with each party separately (bilateral) +2. Identify common ground across pairs +3. Bring all parties together with draft agreement +4. Address remaining differences in group + +**When to Use:** +- Strong personality conflicts +- Very different interests +- Need to build coalitions first + +### Strategy 2: Issue-by-Issue + +**Process:** +1. Break negotiation into separate issues +2. Tackle easiest issue first (build momentum) +3. Trade across issues (I give on X, you give on Y) +4. Build package deal + +**When to Use:** +- Multiple dimensions to negotiate +- Opportunity for trade-offs +- Need small wins to build trust + +### Strategy 3: Mediator-Led + +**Process:** +1. Neutral mediator facilitates +2. Mediator controls agenda and process +3. Mediator caucuses with parties separately +4.

+1. **Include diverse perspectives**: Don't let one person score alone (eng overestimates effort, sales overestimates impact) + - ✓ Get engineering, product, sales, customer success input + - ❌ PM scores everything solo + +2. **Differentiate scores**: If everything is scored 3, you haven't prioritized + - ✓ Force rank or use wider scale (1-10) + - ✓ Aim for distribution: few 1s/5s, more 2s/4s, many 3s + - ❌ All items scored 2.5-3.5 + +3. **Question extreme scores**: High-impact low-effort items are rare (if you have 10, something's wrong) + - ✓ "Why haven't we done this already?" test for quick wins + - ❌ Wishful thinking (underestimating effort, overestimating impact) + +4. **Make scoring transparent**: Document why each score was assigned + - ✓ "Effort=4 because requires 3 teams, new infrastructure, 6-week timeline" + - ❌ "Effort=4" with no rationale + +5. **Revisit scores periodically**: Effort/impact change as context evolves + - ✓ Re-score quarterly or after major changes (new tech, new team size) + - ❌ Use 2-year-old scores + +6. **Don't ignore dependencies**: Low-effort items blocked by high-effort prerequisites aren't quick wins + - ✓ "Effort=2 for task, but depends on Effort=5 migration" + - ❌ Score task in isolation + +7. **Beware of "strategic" override**: Execs calling everything "high impact" defeats prioritization + - ✓ "Strategic" is one dimension, not a veto

Calculate weighted score: `Score = Σ(criterion_score × criterion_weight)` + +**Example**: + +| Criteria | Weight | Feature A Score | Feature A Weighted | Feature B Score | Feature B Weighted | +|----------|--------|----------------|-------------------|----------------|-------------------| +| Revenue | 40% | 4 | 1.6 | 2 | 0.8 | +| Strategic | 30% | 5 | 1.5 | 4 | 1.2 | +| User Pain | 20% | 3 | 0.6 | 5 | 1.0 | +| Complexity | 10% | 2 (low) | 0.2 (penalty) | 4 (high) | 0.4 (penalty) | +| **Total** | **100%** | - | **3.9** | - | **3.0** | + +**Decision**: Feature A scores higher (3.9 vs 3.0) due to revenue and strategic fit + +**Advantages**: Transparent, customizable to organization's values +**Disadvantages**: Can become analysis paralysis with too many criteria + +### Kano Model (Customer Satisfaction) + +**When to use**: Understanding which features delight vs must-have vs don't-matter + +**Categories**: +- **Must-Be (Basic)**: Absence causes dissatisfaction, presence is expected (e.g., product works, no security bugs) +- **Performance (Linear)**: More is better, satisfaction increases linearly (e.g., speed, reliability) +- **Delighters (Excitement)**: Unexpected features that wow users (e.g., dark mode before it was common) +- **Indifferent**: Users don't care either way (e.g., internal metrics dashboard for end users) +- **Reverse**: Some users actively dislike (e.g., forced tutorials, animations) + +**Survey technique**: +- Ask functional question: "How would you feel if we had feature X?" (Satisfied / Expected / Neutral / Tolerate / Dissatisfied) +- Ask dysfunctional question: "How would you feel if we did NOT have feature X?" +- Map responses to category + +**Prioritization strategy**: +1. **Must-Be first**: Fix broken basics (dissatisfiers) +2. **Delighters for differentiation**: Quick wins that wow +3. **Performance for competitiveness**: Match or exceed competitors +4. **Avoid indifferent/reverse**: Don't waste time + +**Example**: +- Must-Be: Fix crash on login (everyone expects app to work) +- Performance: Improve search speed from 2s to 0.5s +- Delighter: Add "undo send" for emails (unexpected delight) +- Indifferent: Add 50 new color themes (most users don't care) + +### Value vs Complexity (Alternative Labels) + +**When to use**: Same as effort-impact, but emphasizes business value and technical complexity + +**Axes**: +- **X-axis: Complexity** (technical difficulty, dependencies, unknowns) +- **Y-axis: Value** (business value, strategic value, user value) + +**Quadrants** (same concept, different framing): +- **High Value, Low Complexity** = Quick Wins (same) +- **High Value, High Complexity** = Strategic Investments (same as Big Bets) +- **Low Value, Low Complexity** = Nice-to-Haves (same as Fill-Ins) +- **Low Value, High Complexity** = Money Pits (same as Time Sinks) + +**When to use this framing**: Technical audiences respond to "complexity", business audiences to "value" + +--- + +## 2. Alternative Prioritization Models + +### MoSCoW (Must/Should/Could/Won't) + +**When to use**: Fixed-scope projects (e.g., product launch, migration) with deadline constraints + +**Categories**: +- **Must Have**: Non-negotiable, project fails without (e.g., core functionality, security, legal requirements) +- **Should Have**: Important but not critical, defer if needed (e.g., nice UX, analytics) +- **Could Have**: Desirable if time/budget allows (e.g., polish, edge cases) +- **Won't Have (this time)**: Out of scope, revisit later (e.g., advanced features, integrations) + +**Process**: +1. List all requirements +2. Stakeholders categorize each (force hard choices: only 60% can be Must/Should) +3. Build Must-Haves first, then Should-Haves, then Could-Haves if time remains +4. Communicate Won't-Haves to set expectations + +**Example (product launch)**: +- **Must**: User registration, core workflow, payment processing, security +- **Should**: Email notifications, basic analytics, help docs +- **Could**: Dark mode, advanced filters, mobile app +- **Won't**: Integrations, API, white-labeling (v2 scope) + +**Advantages**: Forces scope discipline, clear for deadline-driven work +**Disadvantages**: Doesn't account for effort (may put high-effort items in Must) + +### Cost of Delay (CD3: Cost, Duration, Delay) + +**When to use**: Time-sensitive decisions where delaying has quantifiable revenue/strategic cost + +**Formula**: `CD3 Score = Cost of Delay / Duration` +- **Cost of Delay**: $/month of delaying this (revenue loss, market share, customer churn) +- **Duration**: Months to complete + +**Example**: +- Feature A: $100K/mo delay cost, 2 months duration → **$50K/mo score** +- Feature B: $200K/mo delay cost, 5 months duration → **$40K/mo score** +- **Decision**: Feature A higher score (faster time-to-value despite lower total CoD) + +**When to use**: Competitive markets, revenue-critical features, time-limited opportunities (e.g., seasonal) + +**Advantages**: Explicitly values speed to market +**Disadvantages**: Requires estimating revenue impact (often speculative) + +### Opportunity Scoring (Jobs-to-be-Done) + +**When to use**: Understanding which user jobs are underserved (high importance, low satisfaction) + +**Survey**: +- Ask users to rate each "job" on: + - **Importance**: How important is this outcome? (1-5) + - **Satisfaction**: How well does current solution satisfy? (1-5) + +**Opportunity Score**: `Importance + max(Importance - Satisfaction, 0)` +- Score ranges 0-10 +- **>8 = High opportunity** (important but poorly served) +- **<5 = Low opportunity** (either unimportant or well-served) + +**Example**: +- Job: "Quickly find relevant past conversations" + - Importance: 5 (very important) + - Satisfaction: 2 (very dissatisfied) + - Opportunity: 5 + (5-2) = **8 (high opportunity)** → prioritize search improvements + +- Job: "Customize notification sounds" + - Importance: 2 (not important) + - Satisfaction: 3 (neutral) + - Opportunity: 2 + 0 = **2 (low opportunity)** → deprioritize + +**Advantages**: User-centric, identifies gaps between need and solution +**Disadvantages**: Requires user research, doesn't account for effort + +--- + +## 3. Stakeholder Alignment Techniques + +### Silent Voting (Avoid Anchoring Bias) + +**Problem**: First person to score influences others (anchoring bias), HIPPO dominates +**Solution**: Everyone scores independently, then discuss + +**Process**: +1. Each stakeholder writes scores on sticky notes (don't share yet) +2. Reveal all scores simultaneously +3. Discuss discrepancies (why did eng score Effort=5 but product scored Effort=2?) +4. Converge on consensus score + +**Tools**: Planning poker (common in agile), online voting (Miro, Mural) + +### Forced Ranking (Avoid "Everything is High Priority") + +**Problem**: Stakeholders rate everything 4-5, no differentiation +**Solution**: Force stack ranking (only one item can be #1) + +**Process**: +1. List all items +2. Stakeholders must rank 1, 2, 3, ..., N (no ties allowed) +3. Convert ranks to scores (e.g., top 20% = 5, next 20% = 4, middle 20% = 3, etc.) + +**Variant: $100 Budget**: +- Give stakeholders $100 to "invest" across all items +- They allocate dollars based on priority ($30 to A, $25 to B, $20 to C, ...) +- Items with most investment are highest priority + +### Weighted Stakeholder Input (Account for Expertise) + +**Problem**: Not all opinions are equal (eng knows effort, sales knows customer pain) +**Solution**: Weight scores by expertise domain + +**Example**: +- Effort score = 100% from Engineering (they know effort best) +- Impact score = 40% Product + 30% Sales + 30% Customer Success (all know value) + +**Process**: +1. Define who estimates what (effort, user impact, revenue, etc.) +2. Assign weights (e.g., 60% engineering + 40% product for effort) +3. Calculate weighted average: `Score = Σ(stakeholder_score × weight)` + +### Pre-Mortem for Controversial Items + +**Problem**: Stakeholders disagree on whether item is Quick Win or Time Sink +**Solution**: Run pre-mortem to surface hidden risks/assumptions + +**Process**: +1. Assume item failed spectacularly ("We spent 6 months and it failed") +2. Each stakeholder writes down "what went wrong" (effort blowups, impact didn't materialize) +3. Discuss: Are these risks real? Should we adjust scores or descope? + +**Example**: +- Item: "Build mobile app" (scored Impact=5, Effort=3) +- Pre-mortem reveals: "App store approval took 3 months", "iOS/Android doubled effort", "Users didn't download" +- **Revised score**: Impact=3 (uncertain), Effort=5 (doubled for two platforms) → Time Sink, defer + +--- + +## 4. Data-Driven Prioritization + +### Usage Analytics (Prioritize High-Traffic Areas) + +**When to use**: Product improvements where usage data is available + +**Metrics**: +- **Page views / Feature usage**: Improve high-traffic areas first (more users benefit) +- **Conversion funnel**: Fix drop-off points with biggest impact (e.g., 50% drop at checkout) +- **Support tickets**: High ticket volume = high user pain + +**Example**: +- Dashboard page: 1M views/mo, 10% bounce rate → **100K frustrated users** → high impact +- Settings page: 10K views/mo, 50% bounce rate → **5K frustrated users** → lower impact +- **Decision**: Fix dashboard first (20× more impact) + +**Advantages**: Objective, quantifies impact +**Disadvantages**: Ignores new features (no usage data yet), low-traffic areas may be high-value for specific users + +### A/B Test Results (Validate Impact Assumptions) + +**When to use**: Uncertain impact; run experiment to measure before committing + +**Process**: +1. Build minimal version of feature (1-2 weeks) +2. A/B test with 10% of users +3. Measure impact (conversion, retention, revenue, NPS) +4. If impact validated, commit to full version; if not, deprioritize + +**Example**: +- Hypothesis: "Adding social login will increase signups 20%" +- A/B test: 5% increase (not 20%) +- **Decision**: Impact=3 (not 5 as assumed), deprioritize vs other items + +**Advantages**: Reduces uncertainty, validates assumptions before big bets +**Disadvantages**: Requires experimentation culture, time to run tests + +### Customer Request Frequency (Vote Counting) + +**When to use**: Feature requests from sales, support, customers + +**Metrics**: +- **Request count**: Number of unique customers asking +- **Revenue at risk**: Total ARR of customers requesting (enterprise vs SMB) +- **Churn risk**: Customers threatening to leave without feature + +**Example**: +- Feature A: 50 SMB customers requesting ($5K ARR each) = **$250K ARR** +- Feature B: 2 Enterprise customers requesting ($200K ARR each) = **$400K ARR** +- **Decision**: Feature B higher impact (more revenue at risk) despite fewer requests + +**Guardrail**: Don't just count votes (10 vocal users ≠ real demand), weight by revenue/strategic value + +### NPS/CSAT Drivers Analysis + +**When to use**: Understanding which improvements drive customer satisfaction most + +**Process**: +1. Collect NPS/CSAT scores +2. Ask open-ended: "What's the one thing we could improve?" +3. Categorize feedback (performance, features, support, etc.) +4. Correlate categories with NPS (which issues are mentioned by detractors most?) + +**Example**: +- Detractors (NPS 0-6) mention "slow performance" 80% of time +- Passives (NPS 7-8) mention "missing integrations" 60% +- **Decision**: Fix performance first (bigger impact on promoter score) + +--- + +## 5. Roadmap Optimization + +### Dependency Mapping (Critical Path) + +**Problem**: Items with dependencies can't start until prerequisites complete +**Solution**: Map dependency graph, identify critical path + +**Process**: +1. List all items with dependencies (A depends on B, C depends on A and D) +2. Draw dependency graph (use tools: Miro, Mural, project management software) +3. Identify critical path (longest chain of dependencies) +4. Parallelize non-dependent work + +**Example**: +- Quick Win A (2 weeks) → Big Bet B (8 weeks) → Quick Win C (1 week) = **11 week critical path** +- Quick Win D (2 weeks, no dependencies) can run in parallel with A +- **Optimized timeline**: 11 weeks instead of 13 weeks (if sequential) + +### Team Velocity and Capacity Planning + +**Problem**: Overcommitting to more work than team can deliver +**Solution**: Use historical velocity to forecast capacity + +**Process**: +1. Measure past velocity (effort points completed per sprint/quarter) +2. Estimate total capacity (team size × utilization × time period) +3. Don't plan >70-80% of capacity (buffer for unknowns, support, bugs) + +**Example**: +- Team completes 20 effort points/quarter historically +- Next quarter roadmap: 30 effort points planned +- **Problem**: 150% overcommitted +- **Fix**: Cut lowest-priority items (time sinks, fill-ins) to fit 16 effort points (80% of 20) + +**Guardrail**: If you consistently complete <50% of roadmap, estimation is broken (not just overcommitted) + +### Incremental Delivery (Break Big Bets into Phases) + +**Problem**: Big Bet takes 6 months; no value delivery until end +**Solution**: Break into phases that deliver incremental value + +**Example**: +- **Original**: "Rebuild reporting system" (6 months, Effort=5) +- **Phased**: + - Phase 1: Migrate 3 most-used reports (1 month, Effort=2, Impact=3) + - Phase 2: Add drill-down capability (1 month, Effort=2, Impact=4) + - Phase 3: Real-time data (2 months, Effort=3, Impact=5) + - Phase 4: Custom dashboards (2 months, Effort=3, Impact=3) +- **Benefit**: Ship value after 1 month (not 6), can adjust based on feedback + +**Advantages**: Faster time-to-value, reduces risk, allows pivoting +**Disadvantages**: Requires thoughtful phasing (some work can't be incrementalized) + +### Portfolio Balancing (Mix of Quick Wins and Big Bets) + +**Problem**: Roadmap is all quick wins (no strategic depth) or all big bets (no momentum) +**Solution**: Balance portfolio across quadrants and time horizons + +**Target distribution**: +- **70% Quick Wins + Fill-Ins** (short-term value, momentum) +- **30% Big Bets** (long-term strategic positioning) +- OR by time: **Now (0-3 months)**: 60%, **Next (3-6 months)**: 30%, **Later (6-12 months)**: 10% + +**Example**: +- Q1: 5 quick wins + 1 big bet Phase 1 +- Q2: 3 quick wins + 1 big bet Phase 2 +- Q3: 4 quick wins + 1 new big bet start +- **Result**: Consistent value delivery (quick wins) + strategic progress (big bets) + +--- + +## 6. Common Pitfalls and Solutions + +### Pitfall 1: Solo Scoring (No Stakeholder Input) + +**Problem**: PM scores everything alone, misses engineering effort or sales context +**Solution**: Multi-stakeholder scoring session (2-hour workshop) + +**Workshop agenda**: +- 0-15min: Align on scoring scales (calibrate with examples) +- 15-60min: Silent voting on effort/impact for all items +- 60-90min: Discuss discrepancies, converge on consensus +- 90-120min: Plot matrix, identify quadrants, sequence roadmap + +### Pitfall 2: Analysis Paralysis (Perfect Scores) + +**Problem**: Spending days debating if item is Effort=3.2 or Effort=3.4 +**Solution**: Good-enough > perfect; prioritization is iterative + +**Guardrail**: Limit scoring session to 2 hours; if still uncertain, default to conservative (higher effort, lower impact) + +### Pitfall 3: Ignoring Dependencies + +**Problem**: Quick Win scored Effort=2, but depends on Effort=5 migration completing first +**Solution**: Score standalone effort AND prerequisite effort separately + +**Example**: +- Item: "Add SSO login" (Effort=2 standalone) +- Depends on: "Migrate to new auth system" (Effort=5) +- **True effort**: 5 (for new roadmaps) or 2 (if migration already planned) + +### Pitfall 4: Strategic Override ("CEO Wants It") + +**Problem**: Exec declares item "high priority" without scoring, bypasses process +**Solution**: Make execs participate in scoring, apply same framework + +**Response**: "Let's score this using our framework so we can compare to other priorities. If it's truly high impact and low effort, it'll naturally rise to the top." + +### Pitfall 5: Sunk Cost Fallacy (Continuing Time Sinks) + +**Problem**: "We already spent 2 months on X, we can't stop now" (even if impact is low) +**Solution**: Sunk costs are sunk; evaluate based on future effort/impact only + +**Decision rule**: If you wouldn't start this project today knowing what you know, stop it now + +### Pitfall 6: Neglecting Maintenance (Assuming 100% Project Capacity) + +**Problem**: Roadmap plans 100% of team time, ignoring support/bugs/tech debt/meetings +**Solution**: Reduce capacity by 20-50% for non-project work + +**Realistic capacity**: +- 100% time - 20% support/bugs - 10% meetings - 10% code review/pairing = **60% project capacity** +- If team is 5 people × 40 hrs/wk × 12 weeks = 2400 hrs, only 1440 hrs available for roadmap + +### Pitfall 7: Ignoring User Research (Opinion-Based Scoring) + +**Problem**: Impact scores based on team intuition, not user data +**Solution**: Validate impact with user research (surveys, interviews, usage data) + +**Quick validation**: +- Survey 50 users: "How important is feature X?" (1-5) +- If <50% say 4-5, impact is not as high as assumed +- Adjust scores based on data + +### Pitfall 8: Scope Creep During Execution + +**Problem**: Quick Win (Effort=2) grows to Big Bet (Effort=5) during implementation +**Solution**: Timebox quick wins; if effort exceeds estimate, cut scope or defer + +**Guardrail**: "If this takes >1 week, we stop and re-evaluate whether it's still worth it" + +### Pitfall 9: Forgetting to Say "No" + +**Problem**: Roadmap keeps growing (never remove items), becomes unexecutable +**Solution**: Explicitly cut time sinks, communicate what you're NOT doing + +**Communication template**: "We prioritized X, Y, Z based on impact/effort. This means we're NOT doing A, B, C this quarter because [reason]. We'll revisit in [timeframe]." + +### Pitfall 10: One-Time Prioritization (Never Re-Score) + +**Problem**: Scores from 6 months ago are stale (context changed, new data available) +**Solution**: Re-score quarterly, adjust roadmap based on new information + +**Triggers for re-scoring**: +- Quarterly planning cycles +- Major context changes (new competitor, customer churn, team size change) +- Big bets complete (update dependent items' scores) +- User research reveals new insights diff --git a/skills/prioritization-effort-impact/resources/template.md b/skills/prioritization-effort-impact/resources/template.md new file mode 100644 index 0000000..9f45bb0 --- /dev/null +++ b/skills/prioritization-effort-impact/resources/template.md @@ -0,0 +1,374 @@ +# Prioritization: Effort-Impact Matrix Template + +## Table of Contents +1.

Almost Certain (>80%)**: Expected to occur, historical data confirms, no mitigation in place +- **4 - Likely (60-80%)**: Probably will occur, similar projects had this issue, weak mitigation +- **3 - Possible (40-60%)**: May or may not occur, depends on circumstances, some mitigation in place +- **2 - Unlikely (20-40%)**: Probably won't occur, mitigation in place, low historical precedent +- **1 - Rare (<20%)**: Very unlikely, strong mitigation, no historical precedent + +**Impact Scale (1-5) - adjust dimensions for project context:** + +**For Schedule Impact:** +- **5 - Severe**: >20% delay (e.g., 3-month project delayed 3+ weeks), miss critical deadline, cascading delays +- **4 - Major**: 10-20% delay, miss milestone, affects dependent projects +- **3 - Moderate**: 5-10% delay, timeline buffer consumed, no external impact +- **2 - Minor**: <5% delay, absorbed within sprint/phase, minor schedule pressure +- **1 - Minimal**: <1% delay or no delay, negligible schedule impact + +**For Budget Impact:** +- **5 - Severe**: >20% budget overrun, requires new funding approval, project viability threatened +- **4 - Major**: 10-20% overrun, contingency exhausted, scope cuts required +- **3 - Moderate**: 5-10% overrun, contingency partially used, no scope cuts +- **2 - Minor**: <5% overrun, absorbed within budget flexibility +- **1 - Minimal**: <1% overrun or no budget impact + +**For Scope/Quality Impact:** +- **5 - Severe**: Core functionality lost, customer-facing quality issue, regulatory violation +- **4 - Major**: Important feature cut, significant quality degradation, customer complaints +- **3 - Moderate**: Nice-to-have feature cut, minor quality issue, internal workarounds needed +- **2 - Minor**: Edge case feature cut, cosmetic quality issue +- **1 - Minimal**: No scope or quality impact + +**Composite Impact** (when multiple dimensions affected): +- Use **maximum** of any single dimension (pessimistic, conservative) +- OR use **weighted average**: Schedule 40%, Budget 30%, Scope/Quality 30% + +**Example Scoring:** + +Risk: "Key engineer leaves mid-project" +- Probability: 2 (Unlikely -

✓ Brainstorm risks at project kickoff, use checklists (technical, schedule, resource, etc.) + - ❌ Add risks only after incidents occur (reactive) + +2. **Be specific, not vague**: "Integration fails" is vague, "Vendor API rate limits block migration" is specific + - ✓ "Third-party payment gateway rejects 10% of transactions due to fraud rules" + - ❌ "Payment issues" + +3. **Separate probability and impact**: Don't conflate "bad if it happens" with "likely to happen" + - ✓ Asteroid hits office: Prob=1 (rare), Impact=5 (severe), Score=5 (low priority) + - ❌ Conflating: "This is really bad so it must be high priority" (ignoring low probability) + +4. **Assign named owners, not teams**: "Engineering team" is not accountable, "Sarah (Tech Lead)" is + - ✓ Owner: Sarah (Tech Lead), responsible for monitoring and activating contingency + - ❌ Owner: Engineering Team (diffused responsibility) + +5. **Define mitigation AND contingency**: Mitigation reduces probability, contingency handles if it occurs anyway + - ✓ Mitigation: Prototype integration early (reduce prob). Contingency: Build abstraction layer for quick swap (reduce impact) + - ❌ Only mitigation, no backup plan + +6. **Update regularly**: Stale risk register is worse than none (false confidence) + - ✓ Weekly review for active projects (High/Critical risks), monthly for longer projects + - ❌ Create register at kickoff, never update (probabilities/impacts change as project progresses) + +7. **Retire closed risks**: Don't let register grow indefinitely, archive mitigated/irrelevant risks + - ✓ Mark risk "Closed" with resolution date, move to archive section + - ❌ Keep all risks forever (signal-to-noise ratio degrades) + +8. **Escalate critical risks immediately**: Don't wait for weekly meeting if Critical risk emerges + - ✓ Prob=5 Impact=5 Score=25 → Escalate to exec same day, emergency mitigation + - ❌ Wait for scheduled review (risk could materialize) + +## Quick Reference + +**Resources:** +- **Quick start**: [resources/template.md](resources/template.md) - Risk register template with scoring table, response planning, monitoring log +- **Advanced techniques**: [resources/methodology.md](resources/methodology.md) - Monte Carlo simulation, decision trees, sensitivity analysis, risk aggregation, earned value management +- **Quality check**: [resources/evaluators/rubric_project_risk_register.json](resources/evaluators/rubric_project_risk_register.json) - Evaluation criteria + +**Success criteria:** +- ✓ Identified 15-30 risks across all categories (technical, schedule, resource, external, scope, org) +- ✓ All High/Critical risks (score ≥12) have named owners, mitigation plans, and contingencies +- ✓ Risk scores differentiated (not all scored 6-9; use full 1-25 range) +- ✓ Mitigation and contingency plans are specific and actionable (not "monitor closely") +- ✓ Triggers defined for when to activate contingencies (quantifiable thresholds) +- ✓ Register updated regularly (weekly for active projects, monthly for longer projects) +- ✓ Risk profile matches project phase (high uncertainty at start, decreasing over time) + +**Common mistakes:** +- ❌ Too few risks identified (<10) → incomplete risk picture, false confidence +- ❌ All risks scored medium (6-9) → not differentiated, unclear prioritization +- ❌ Vague risks ("things might not work") → not actionable +- ❌ No risk owners assigned → diffused accountability, mitigation doesn't happen +- ❌ Mitigation without contingency → no backup plan if mitigation fails +- ❌ Created once, never updated → stale data, risks evolve +- ❌ Only negative risks (threats) → missing opportunities (positive risks) +- ❌ Risk register separate from project plan → not integrated into workflow + +**When to use alternatives:** +- **Pre-mortem**: When project hasn't started, want to imagine failure scenarios (complements risk register) +- **FMEA (Failure Mode Effects Analysis)**: Manufacturing/engineering projects needing detailed failure analysis +- **Monte Carlo simulation**: When need probabilistic timeline/budget forecasting (use methodology.md) +- **Decision tree**: When risks involve sequential decisions with branch points +- **Scenario planning**: When risks are strategic/long-term (market

Quantitative Risk Analysis + +### Monte Carlo Simulation + +**When to use**: Estimate project timeline/budget uncertainty by simulating thousands of scenarios + +**Process**: +1. For each task, estimate optimistic/most likely/pessimistic duration (PERT: (O + 4M + P) / 6) +2. Define probability distributions (triangular, normal, log-normal) +3. Run 10,000+ simulations randomizing task durations +4. Analyze outcomes: P50 (50% confidence), P80 (80% confidence), P95 (95% confidence) + +**Example - 3-month project with uncertainty**: +- Deterministic estimate (ignoring risk): 90 days +- P50 (median, 50% confidence): 95 days (5 days buffer) +- P80 (80% confidence): 110 days (20 days buffer) +- P95 (95% confidence): 125 days (35 days buffer) + +**Interpretation**: If you commit to 90-day deadline, 50% chance of missing it. For 80% confidence, need 20-day buffer. + +**Tools**: @RISK (Excel add-in), Crystal Ball, Python (numpy.random), R + +### Three-Point Estimation (PERT) + +**Formula**: Expected Duration = (Optimistic + 4×Most Likely + Pessimistic) / 6 + +**Example**: +- Task: Database migration +- Optimistic (best case, 10% prob): 3 days +- Most Likely (50% prob): 7 days +- Pessimistic (worst case, 10% prob): 15 days +- **PERT Estimate**: (3 + 4×7 + 15) / 6 = **8 days** +- **Standard Deviation**: (15 - 3) / 6 = **2 days** +- **80% Confidence Interval**: 8 ± 1.28×2 = **5.4 to 10.6 days** + +**Advantages**: Accounts for uncertainty, easy to elicit from experts +**Disadvantages**: Assumes symmetric distribution (not always true) + +### Sensitivity Analysis + +**Purpose**: Identify which risks have biggest impact on outcomes (tornado diagram) + +**Process**: +1.

Risk Aggregation and Portfolio View + +### Risk Correlation + +**Problem**: Independent risks: P(both occur) = P(A) × P(B). Correlated risks: much higher. + +**Example**: +- Risk A: Vendor 1 delays (Prob=30%) +- Risk B: Vendor 2 delays (Prob=30%) +- **If independent**: P(both delay) = 0.3 × 0.3 = **9%** +- **If correlated** (same root cause - chip shortage): P(both delay) = **25%+** + +**Mitigation**: Identify correlated risks (shared root causes: economy, weather, supply chain), don't assume independence + +### Expected Monetary Value (EMV) + +**Formula**: EMV = Σ (Probability × Impact) for all risks + +**Example - 3 risks**: +| Risk | Prob | Impact | EMV | +|------|------|--------|-----| +| Vendor delay | 40% | -$100K | **-$40K** | +| Quality issue | 20% | -$50K | **-$10K** | +| Early completion (opportunity) | 30% | +$30K | **+$9K** | +| **Total EMV** | | | **-$41K** | + +**Interpretation**: Expected value of risk exposure is -$41K. Budget $50K contingency reserve (EMV + buffer). + +**Use case**: Prioritize mitigation by EMV (biggest expected loss first), size contingency reserves + +### Risk Burn-Down Chart + +**Purpose**: Track risk evolution over project lifecycle (like sprint burn-down) + +**Metrics**: +- Total risk exposure (sum of all risk scores or EMV) +- Number of open risks by priority (Critical/High/Medium/Low) +- Risk velocity (new risks - closed risks per week) + +**Healthy pattern**: +- Risk exposure decreases over time (mitigation working) +- Critical/High risks trend to zero (resolved or mitigated to Medium/Low) +- Risk velocity neutral or negative (closing faster than opening) + +**Red flag pattern**: +- Risk exposure increasing (mitigation not working, new issues emerging) +- Critical/High risks increasing (problems escalating) +- Risk velocity positive (opening faster than closing → overwhelmed) + +--- + +## 3. Advanced Probability Estimation + +### Base Rate Neglect (Avoid Overconfidence) + +**Problem**: People ignore historical frequencies, overestimate unique circumstances + +**Example**: +- Question: "What's probability our migration succeeds on time?" +- Naive answer: "We're confident, 90%" (overconfident, ignores history) +- **Base rate check**: "What % of similar migrations succeed on time historically?" + - Industry data: 40% of migrations hit deadline + - Our company: 3 of last 5 migrations were late (60% late) +- **Adjusted estimate**: Start with 40-60%, adjust up/down based on specific factors + +**Process**: +1. Find reference class (similar past projects) +2. Calculate base rate (how often did X happen?) +3. Adjust for unique factors (better team? More complexity?) +4. Avoid overweighting unique factors (regression to mean) + +### Calibration Training + +**Goal**: Improve probability estimates by testing against reality + +**Exercise**: +1. Make 20 predictions with confidence intervals (e.g., "Project will take 30-50 days, 80% confident") +2. Track outcomes (how many fell within your interval?) +3. **Well-calibrated**: If you say 80%, 16 of 20 (80%) should fall within interval +4. **Overconfident**: If only 10 of 20 (50%) fall within interval, you're underestimating uncertainty + +**Debiasing**: +- If overconfident: Widen intervals, add more uncertainty +- If underconfident: Narrow intervals, trust your judgment more +- Repeat calibration exercises quarterly to maintain skills + +### Decomposition for Probability + +**Problem**: Hard to estimate "What's probability of successful launch?" +**Solution**: Break into sub-components with clearer probabilities + +**Example**: +- P(successful launch) = P(tech ready) × P(market demand) × P(no competitor) × P(ops ready) +- P(tech ready) = 80% (prototype works, 2 minor bugs) +- P(market demand) = 60% (50 customer interviews, 60% said "definitely buy") +- P(no competitor launch first) = 70% (intel says competitor 6 months behind) +- P(ops ready) = 90% (simple deployment, done 10× before) +- **P(successful launch)** = 0.8 × 0.6 × 0.7 × 0.9 = **30%** + +**Insight**: Overall probability much lower than intuition. Focus mitigation on market demand (weakest link). + +--- + +## 4. Decision Trees and Sequential Risks + +### When Risks Have Dependencies + +**Example - Sequential decisions**: +``` + ┌─ Prototype succeeds (60%) ─> Build (cost: $200K) ─┐ +Start ($50K) ─> Prototype ├─> Success ($1M value) + └─ Prototype fails (40%) ─> Stop (cost: $50K) ┘ +``` + +**Expected Value**: +- EV(Prototype) = 0.6 × ($1M - $200K - $50K) + 0.4 × (-$50K) = **$430K** +- Decision: Prototype (EV = $430K) vs Don't Start (EV = $0) → **Prototype wins** + +**Fold-back method**: +1. Start at end nodes (outcomes) +2. Work backwards, calculating EV at each decision node +3. Choose branch with highest EV at each decision + +**Value of information**: +- If perfect test costs $20K and resolves prototype uncertainty → EV = $1M - $200K - $20K = $780K +- Value of info = $780K - $430K = **$350K** → worth paying up to $350K for perfect info + +--- + +## 5. Earned Value Management for Risk + +### Integrating Risks into EVM + +**Standard EVM**: +- Planned Value (PV): Budget for work scheduled +- Earned Value (EV): Budget for work completed +- Actual Cost (AC): Actual spend +- Schedule Variance (SV) = EV - PV (negative = behind schedule) +- Cost Variance (CV) = EV - AC (negative = over budget) + +**Risk-Adjusted EVM**: +- **Budget At Completion (BAC)**: $500K baseline +- **Risk Reserve**: $50K (from EMV calculation) +- **Total Budget**: $550K (BAC + Reserve) +- **Risk Burn Rate**: How fast are risks being retired vs reserve consumed? + +**Metrics**: +- **Risk-Adjusted EAC** (Estimate At Completion): BAC + Remaining Risk EMV + Cost Overruns +- **Contingency Draw-Down**: % of risk reserve consumed vs % of project complete + - Healthy: 30% reserve used, 40% project complete (consuming slower than progress) + - Unhealthy: 60% reserve used, 30% project complete (consuming faster → may exhaust reserve) + +--- + +## 6.

Test highest-risk assumption first. See [Common Patterns](#common-patterns) for typical assumptions by domain. + +**Step 2: Choose approach** + +Match test method to assumption and available time/budget. See [Fidelity Ladder](#fidelity-ladder) for choosing appropriate fidelity. Use [resources/template.md](resources/template.md) for experiment design. + +**Step 3: Design and build minimum test** + +Create simplest artifact that tests assumption (landing page, paper prototype, manual service delivery). See [resources/methodology.md](resources/methodology.md) for specific techniques (fake door, concierge, Wizard of Oz, paper prototyping). + +**Step 4: Run experiment** + +Deploy test, recruit participants, collect quantitative data (sign-ups, clicks, payments) and qualitative feedback (interviews, observations). Aim for minimum viable data (n=5-10 for qualitative, n=100+ for quantitative confidence). + +**Step 5: Analyze and decide** + +Compare results to success criteria (e.g., "10% conversion validates demand"). Decide: Pivot (assumption wrong, change direction), Persevere (assumption validated, build it), or Iterate (mixed results, refine and re-test). + +## Common Patterns + +**By assumption type:** + +**Demand Assumption** ("People want this"): +- Test: Fake door (landing page with "Buy Now" → "Coming Soon"), pre-orders, waitlist sign-ups +- Success criteria: X% conversion, Y sign-ups in Z days +- Example: "10% of visitors sign up for waitlist in 2 weeks" → validates demand + +**Pricing Assumption** ("People will pay $X"): +- Test: Price on landing page, offer with multiple price tiers, A/B test prices +- Success criteria: Z% conversion at target price +- Example: "5% convert at $49/mo" → validates pricing + +**Workflow Assumption** ("This solves user problem in intuitive way"): +- Test: Paper prototype, task completion with clickable prototype +- Success criteria: X% complete task without help, what they say + - ✓ "50% clicked 'Buy Now' but 0% completed payment" (real behavior → pricing/friction issue) + - ❌ "Users said they'd pay $99/mo" (opinion, not reliable predictor) + +6. **Be transparent about faking it**: Ethical pretotyping + - ✓ "Sign up for early access" or "Launching soon" (honest) + - ❌ Charging credit cards for fake product, promising features you won't build (fraud) + +7. **Throw away prototypes**: Don't turn prototype code into production + - ✓ Rebuild with proper architecture after validation + - ❌ Ship prototype code (technical debt, security issues, scalability problems) + +8. **Iterate quickly**: Multiple cheap tests > one expensive test + -

closely**: Delays on critical path directly delay project +- **Add buffer**: 20-30% to critical path tasks (Murphy's Law) +- **Resource priority**: Staff critical path first +- **Fast-track**: Can non-critical work be delayed to help critical path? +- **Crash**: Add resources to shorten critical path (diminishing returns, Brook's Law applies) + +## Common Patterns + +**Pattern 1: Product Launch with Fixed Date** +- **Target**: Product live by date, serving customers +- **Key milestones (backward)**: GA launch, beta testing, feature freeze, alpha testing, MVP, design complete, requirements locked +- **Critical path**: Usually design → engineering → testing (sequential) +- **Buffer**: 20-30% on engineering (unknowns), 20% on testing (bugs) + +**Pattern 2: Compliance Deadline (Regulatory)** +- **Target**: Compliant by regulatory deadline (cannot slip) +- **Key milestones**: Audit passed, controls implemented, policies updated, gap analysis complete +- **Critical path**: Gap analysis → remediation → validation +- **Buffer**: 40%+ (regulatory risk intolerant, build extra time) + +**Pattern 3: Strategic Transformation (Multi-Year)** +- **Target**: Future state vision (e.g., "Cloud-native architecture by 2027") +- **Key milestones (annual)**: Year 3 (full migration), Year 2 (50% migrated), Year 1 (pilot complete), Year 0 (strategy approved) +- **Critical path**: Foundation work (pilot, learnings) enables scale +- **Buffer**: 30%+ per phase (unknowns compound over time) + +**Pattern 4: Event Planning (Conference, Launch Event)** +- **Target**: Event happens on date, attendees have great experience +- **Key milestones**: Event day, rehearsal, content ready, speakers confirmed, venue booked, date announced +- **Critical path**: Venue booking (long lead time) often on critical path +- **Buffer**: 10-20% (events have hard deadlines, less flexible) + +## Guardrails + +**Feasibility checks:** +- **Available time ≥ required time**: If backward timeline reaches before today, goal is infeasible +- **Buffer included**: Add 20-30% to estimates (Hofstadter's Law: "It always takes longer than you expect, even when you account for Hofstadter's Law") +- **Dependencies realistic**: Can dependent work actually be done in sequence (handoff time, rework)? +- **Resource constraints**: Do we have people/budget to parallelize where needed? + +**Common pitfalls:** +- **Optimistic sequencing**: Assuming perfect handoffs, no rework, no blockers +- **Ignoring dependencies**: "We can start everything at once" → actually highly sequential +- **No buffer**: Plans with 0% slack fail on first hiccup +- **Scope creep**: Target outcome expands during execution, invalidates backcast +- **Sunk cost fallacy**: When backcast shows infeasibility, adjust scope or date (don't plow ahead) + +**Quality standards:** +- Milestones have clear deliverables (not "working on X") +- Dependencies explicitly mapped (not assumed) +- Critical path identified (know

approaches**: Combine elements from multiple perspectives (e.g., freemium = marketing + finance) +- **Constraints as creativity**: Use one role's limits to sharpen another's solution (e.g., budget constraint forces prioritization) +- **Risk mitigation**: Address fears with safeguards (e.g., eng fears tech debt → schedule refactoring sprint) + +**When perspectives are truly incompatible:** +- **Escalate decision**: Flag for leadership with clear tradeoff framing +- **Run experiment**: Pilot to gather data, convert opinions to evidence +- **Decouple decisions**: Split into multiple

Engineering (control, customization), Finance (TCO), Product (time-to-market), Legal (vendor risk), Operations (support burden) +- **Typical tensions**: Eng wants control, Finance sees build cost underestimation, PM sees opportunity cost of delay +- **Synthesis paths**: Pilot buy option with build fallback, build core/buy periphery, time-box build with buy backstop + +**Pattern 2: Feature Prioritization** +- **Roles**: PM (roadmap vision), Engineering (technical feasibility), Design (UX quality), Sales (customer requests), Users (actual need) +- **Typical tensions**: Sales wants

+**Pattern 3: Pricing Strategy** +- **Roles**: Finance (margin), Marketing (positioning), Sales (close rate), Customers (value perception), Product (feature gating) +- **Typical tensions**: Finance wants premium, Sales wants competitive, Marketing wants simple, Product wants value-based tiers +- **Synthesis paths**: Tiered pricing (serves multiple segments), usage-based (aligns value), anchoring (premium + standard) + +**Pattern 4: Organizational Change (e.g., return-to-office)** +- **Roles**: Leadership (collaboration), Employees (flexibility), HR (retention), Finance (real estate cost), Managers (productivity) +- **Typical tensions**: Leadership sees serendipity loss, Employees see autonomy loss, Finance sees sunk cost, HR sees turnover +- **Synthesis paths**: Hybrid model (balance), role-based policy (nuance), trial periods (data-driven), opt-in incentives (voluntary) + +**Pattern 5: Technical Migration** +- **Roles**: Engineering (technical improvement), PM (feature freeze), Users (potential downtime), DevOps (operational risk), Finance (ROI) +- **Typical tensions**: Eng sees long-term benefit, PM sees short-term cost, Users fear disruption, Finance wants ROI proof +-

caricature roles (e.g., "Finance only cares about cost cutting") +- Inhabit perspective charitably—what's the *strongest* version of this viewpoint? +- Seek conflicting evidence to your own bias + +**Distinguish position from interest:** +- **Position**: What they say they want (surface demand) +- **Interest**: Why they want it (underlying need) +- Example: "I want this feature" (position) because "customers are churning" (interest = retention) +- Synthesis works at interest level, not position level + +**Acknowledge information asymmetry:** +- Some roles have context others lack (e.g., Legal sees confidential liability exposure) +- Flag assumptions: "If Legal has info we don't, that could change this analysis" +- Invite real stakeholders to validate your perspective-taking + +**Don't replace actual stakeholder input:** +- Role-switch is for *preparing* conversations, not *replacing* them +- Use to pressure-test before presenting, not as substitute for gathering input +-

Stakeholder Mapping & Selection + +### RACI Matrix (Responsibility Assignment) + +Map stakeholders by their relationship to the decision: + +- **R** (Responsible): Does the work, executes the decision +- **A** (Accountable): Has decision authority, owns outcome (only ONE per decision) +- **C** (Consulted): Provides input, must be heard before deciding +- **I** (Informed): Notified after decision, affected but not consulted + +**Example (API deprecation decision):** +- **R**: Engineering (implements deprecation, migration tooling) +- **A**: VP Engineering (final call on timeline and support model) +- **C**: Product (customer impact), Finance (revenue implications), Customer Success (migration support) +- **I**: Sales (so they can communicate to prospects), Marketing (public messaging) + +**Selection rule**: Always include **A** (decision authority). Include **R** if execution feasibility is uncertain. Include **C** stakeholders with veto power or critical constraints. Consider **I** stakeholders if their reaction could derail implementation. + +### Power-Interest Matrix + +Map stakeholders by **power** (ability to influence decision) and **interest** (how much they care): + +``` +High Interest, High Power → MANAGE CLOSELY (key players) +High Interest, Low Power → KEEP INFORMED (advocates/resistors) +Low Interest, High Power → KEEP SATISFIED (don't let them block) +Low Interest, Low Power → MONITOR (minimal engagement) +``` + +**Example (pricing change):** +- **High Power, High Interest**: CFO (margin), Sales VP (quota), top customers (retention) +- **High Power, Low Interest**: CEO (busy, delegates to CFO unless escalated) +- **Low Power, High Interest**: Individual sales reps (compensation), customer success managers (renewal risk) +- **Low Power, Low Interest**: Marketing ops (just implements new pricing in systems) + +**Selection for role-switch**: Focus on high-interest stakeholders (top two quadrants). Include high-power stakeholders even if low interest (they can block). Deprioritize low-power, low-interest (not decision-critical). + +### Influence Mapping (Who Influences Whom) + +Some stakeholders don't decide but influence deciders: + +**Example (hospital EMR selection):** +- **Formal authority**: CIO (signs contract), CFO (budget approval) +- **Informal influence**: Chief of Surgery (respected voice, if she opposes no one proceeds), Head of Nursing (staff adoption critical) +- **Technical veto**: CISO (security compliance), Legal (contract terms) + +**Map influence paths**: Identify who the decision authority listens to. Include those influencers in role-switch even if they lack formal authority. + +## 2. Cognitive Empathy Techniques + +### Perspective-Taking Protocol + +**Step 1: Inhabit the role's context** +- What is this role measured on? (OKRs, KPIs, promotion criteria) +- What are they accountable for? (what gets them fired if it fails) +- What information do they have that others don't? (asymmetric context) +- What pressures are they under? (boss's expectations, quarterly reviews, competitive threats) + +**Step 2: Adopt their time horizon** +- **Short-term** (this quarter): Sales (quota), Support (ticket backlog) +- **Medium-term** (this year): Product (roadmap), Engineering (technical debt) +- **Long-term** (3+ years): Leadership (strategy), Legal (precedent setting) + +Conflicts often arise from mismatched time horizons (sales wants deal today, eng sees 5-year maintenance burden). + +**Step 3: Understand their incentive structure** +- **Aligned incentives**: Marketing and Sales both want customer acquisition (but marketing = leads, sales = closed deals) +- **Misaligned incentives**: Sales (maximize deal size) vs Finance (minimize discounts) +- **Perverse incentives**: Support (minimize handle time) vs Customers (thorough resolution) + +**Step 4: Identify their constraints** +- **Resource constraints**: Headcount, budget, tooling access +- **Time constraints**: Quarterly deadlines, regulatory timelines, market windows +- **Process constraints**: Approval chains, audit requirements, compliance gates +- **Political constraints**: Board expectations, stakeholder promises, prior commitments + +### Steel-Manning Perspectives + +**Steel-manning**: Construct the *strongest possible* version of a role's position (opposite of strawman). + +**Process**: +1. State their position as they would state it (use their language) +2. Identify the strongest evidence/reasoning for that position +3. Articulate what they might be right about (even if you disagree) +4. Note what legitimate values or priorities drive their stance + +**Example (feature prioritization conflict):** + +**Strawman (weak)**: "Sales just wants to promise customers everything to close deals, they don't care about product quality" + +**Steel-man (strong)**: "Sales sees customer requests as real market signals—if multiple prospects ask for the same capability, it indicates unmet need and competitive gap. Prioritizing these features captures revenue that would otherwise go to competitors and validates product-market fit. Sales fears that saying 'no' to customer requests will result in lost deals, making it harder to hit quota, and signaling to the market that we're not responsive to customer needs." + +Steel-manning builds trust when you present perspectives to stakeholders ("you see I understood your position") and surfaces legitimate concerns that deserve addressing. + +### Position vs Interest Negotiation + +**Position**: What they say they want (surface demand) +**Interest**: Why they want it (underlying need) + +**Example**: +- **Position**: "We need this feature by Q1" +- **Interest**: "We promised a key customer in the sales cycle, and if we don't deliver we risk $500K annual contract and relationship damage" + +**Why this matters**: You can often satisfy the interest without meeting the position. +- Alternative to building feature by Q1: Offer workaround solution, partner integration, or professional services to satisfy customer while buying time for proper feature in Q2. + +**Uncovering interests**: Ask "why" 2-3 times: +- "Why do you want this feature?" → "Customer is asking for it" +- "Why is this customer important?" → "They're our largest account and up for renewal" +- "Why does this specific feature matter for renewal?" → "Competitor has it, they're considering switching" + +Now you see the interest: competitive differentiation for retention, not the feature itself. + +## 3. Power Dynamics & Decision Authority + +### Decision Rights Framework + +**Types of decision authority:** +- **Autocratic**: One person decides, others provide input (e.g., CEO on strategic pivot) +- **Consultative**: Decision-maker seeks input, but retains final call (e.g., PM on feature prioritization) +- **Consensus**: All stakeholders must agree (e.g., co-founders on equity split) +- **Democratic**: Majority vote (e.g., board approval) +- **Delegated**: Authority holder delegates to expert (e.g., CEO → CTO on tech stack) + +**Role-switch implication**: Synthesis should acknowledge decision authority. If PM has final say on roadmap, synthesis can note "Engineering recommends X but PM decides based on customer commitments." Don't pretend consensus is required when it's not. + +### Veto Power Identification + +Some roles can't make the decision but can block it: + +**Examples:** +- **Legal**: Can veto on liability/compliance grounds (not a suggestion, a blocker) +- **Security**: Can veto on risk grounds (breach could be existential) +- **Finance**: Can veto if budget doesn't exist (hard constraint) +- **Regulatory**: External veto (FDA, FTC, etc. can block regardless of internal consensus) + +**Synthesis strategy**: Address veto-holders first. If Legal says "this contract exposes us to unacceptable IP risk," that's non-negotiable. Synthesis must either fix legal issue or find alternative path. No amount of alignment among other stakeholders overrides veto. + +### Navigating Hierarchy + +**Peer conflicts** (same level, e.g., VP Eng vs VP Product): +- Escalate to shared manager if consensus fails +- Frame as tradeoff for leadership to decide (don't make it personal) +- Offer to run experiment/pilot to gather data (de-emotionalize) + +**Vertical conflicts** (manager vs subordinate): +- Subordinate's role: Make recommendation, provide data, articulate risks +- Manager's prerogative: Override with context subordinate may lack +- Synthesis should acknowledge manager has broader context (benefit of doubt) + +**Cross-functional conflicts** (different orgs): +- Identify shared OKRs or company goals to align on +- Escalate to neutral party (e.g., COO) if functions can't resolve +- Avoid "us vs them"—frame as "how do we both win?" + +## 4. Synthesis Strategies + +### Sequential Decision-Making + +When perspectives conflict, decompose into sequence: + +**Pattern**: "Do X first (satisfies role A), then Y (satisfies role B), then Z (satisfies role C)" + +**Example (build vs buy):** +- **Engineering**: "Build in-house for control" +- **Product**: "Buy to launch faster" +- **Synthesis**: "Buy now to hit market window (Product wins short-term). As we scale, evaluate build for strategic capabilities (Engineering wins long-term). Set decision checkpoint at 10K users (concrete trigger)." + +**Benefits**: Reduces present conflict (only deciding immediate action), creates learning period (gather data before next decision), aligns incentives over time. + +### Hybrid Approaches + +Combine elements from multiple perspectives: + +**Example (pricing strategy):** +- **Finance**: "Charge premium to maximize margin" +- **Sales**: "Offer competitive pricing to win deals" +- **Marketing**: "Simple, transparent pricing" +- **Synthesis**: "Tiered pricing (Finance gets premium tier, Sales gets accessible entry tier, Marketing gets 3 clear tiers with public pricing)" + +**Example (work policy):** +- **Leadership**: "In-office for collaboration" +- **Employees**: "Remote for flexibility" +- **Synthesis**: "Hybrid 3 days/week in-office (Leadership gets collaboration days), 2 days remote (Employees get flexibility), core hours 10am-3pm Tue-Thu (ensures overlap)" + +### Pilot/Experiment to Resolve Uncertainty + +When conflict stems from different predictions, run experiment: + +**Example:** +- **Sales**: "Customers will pay 20% more for premium tier" +- **Product**: "Customers are price-sensitive, will churn at higher price" +- **Synthesis**: "Run 2-week pricing test with 10% of new trials. Measure conversion rate and NPS. Decision rule: If conversion drops <5%, proceed with premium pricing. If drops >10%, stay at current price." + +**Benefits**: Converts opinions to data, de-risks decision, builds consensus around evidence. + +### Constraints as Creative Forcing Function + +Use one role's constraint to sharpen another's solution: + +**Example:** +- **Finance**: "We have $100K budget, not $500K" +- **Product**: "We want features A, B, C, D, E" +- **Synthesis**: "Budget constraint forces ruthless prioritization. Which single feature drives 80% of value? (Pareto principle). Build only that feature to MVP standard in Q1, defer B-E to Q2 based on usage data from A." + +Constraint (budget) forces clearer thinking about value (Product benefits from discipline). + +### Risk Mitigation for Fears + +Address each role's top fear with specific mitigation: + +**Example (technical migration):** +- **Engineering fear**: "Migration will surface hidden dependencies and blow up timeline" + - **Mitigation**: 2-week technical spike to map dependencies, discovery phase with 30% time buffer +- **Product fear**: "Feature freeze will let competitor gain ground" + - **Mitigation**: Incremental migration (no freeze), maintain feature velocity on new system +- **User fear**: "Downtime will disrupt workflows" + - **Mitigation**: Blue-green deployment, rollback plan, phased rollout starting with low-risk cohort + +Naming fears explicitly and mitigating shows you took each perspective seriously. + +## 5. Facilitation for Multi-Stakeholder Alignment + +### Pre-Work for Alignment Meetings + +**Before bringing stakeholders together:** +1. **Identify decision framing**: What exactly are we deciding? (avoid vague "alignment meeting") +2. **Pre-socialize positions**: Talk to each stakeholder 1:1 to understand their stance (no surprises in group) +3. **Find common ground**: Identify 2-3 shared goals to anchor discussion +4. **Prepare synthesis options**: Come with 2-3 proposals that address key interests (don't start from blank slate) +5. **Clarify decision authority**: Who has final say if consensus fails? + +### Facilitation Techniques + +**Round-robin sharing** (ensure all voices heard): +- Each stakeholder shares their perspective (2 min, uninterrupted) +- Others listen without rebutting (defer debate to later) +- Captures positions before conflict dominates + +**Interest articulation** (go beneath positions): +- Facilitator asks: "What outcome would satisfy your core need?" (not "what do you want us to do") +- Reframe positions as interests: "I hear you want X because you're trying to achieve Y" + +**Tradeoff matrix** (make tradeoffs explicit): +- On whiteboard, list options across top, criteria down left side +- Score each option (1-5) against each criterion +- Visually shows why no option is perfect (builds realistic expectations) + +**Consensus-building ladder**: +1. **Full agreement**: Everyone enthusiastically supports +2. **Agreement with minor reservations**: Support with noted concerns +3. **Support with significant reservations**: "I disagree but won't block" +4. **Abstain**: "I have no strong opinion" +5. **Stand aside**: "I disagree but defer to group" +6. **Block**: "I cannot support this" (veto) + +Most decisions don't need Level 1. Level 2-3 is sufficient. Reserve Level 6 (block) for ethical/legal/existential issues. + +### Dealing with Impasse + +**When stakeholders can't agree:** + +**Option 1: Escalate** +- Clearly frame tradeoff for decision authority +- Example: "Engineering recommends A (technical merit), Sales recommends B (customer promise). VP Product, your call." + +**Option 2: Decouple** +- Split into multiple decisions with different owners +- Example: "Engineering decides tech stack (their domain). Product decides feature scope (their domain)." + +**Option 3: Time-box discussion** +- "We'll discuss for 30 min. If no consensus, we'll go with default option C and revisit in 3 months." + +**Option 4: Introduce new information** +- "Let's gather customer feedback / run competitive analysis / build prototype before deciding." + +## 6. Advanced Patterns + +### Divergent Incentives (Sales vs Finance vs Ops) + +**Scenario**: Sales wants custom contracts to close deals, Finance wants standardized pricing to forecast revenue, Operations wants limited SKUs to simplify fulfillment. + +**Tension**: Each role optimizes for different metric (deal size vs predictability vs complexity). + +**Synthesis**: +- **Core offering**: Standardized packages (Finance & Ops win on base case) +- **Custom tier**: Allow customization for enterprise deals >$500K with CFO approval (Sales wins on strategic accounts) +- **Operational tax**: Custom deals pay 20% premium to fund ops complexity (Ops gets resourced, Sales pays for flexibility) + +**Principle**: Tiered approach where standardization is default, customization is available but priced to internalize costs. + +### Temporal Conflicts (Short-Term vs Long-Term) + +**Scenario**: Marketing wants aggressive growth spend (customer acquisition), Finance wants profitability (unit economics), Leadership wants sustainable growth. + +**Tension**: Short-term growth (sacrifice margins) vs long-term health (profitable unit economics). + +**Synthesis**: +- **Phase 1** (Year 1): Growth mode—invest in acquisition, LTV:CAC = 2:1 acceptable (Marketing wins) +- **Phase 2** (Year 2): Efficiency mode—optimize unit economics, LTV:CAC = 4:1 target (Finance wins) +- **Trigger for shift**: Hit $10M ARR or 18 months, whichever comes first (Leadership defines graduation criteria) + +**Principle**: Sequence priorities over time with clear phase transitions. + +### Regulatory/Ethical vs Commercial Tensions + +**Scenario**: Product wants to use customer data for personalization (revenue driver), Privacy/Legal want data minimization (compliance, trust). + +**Tension**: Commercial opportunity (more data = better product) vs regulatory/ethical constraint (less data = lower risk). + +**Synthesis**: +- **Explicit consent**: Only use data if customer opts in (Legal satisfied—compliant) +- **Value exchange**: Show customer how data improves their experience (Product satisfied—retention driver) +- **Minimization**: Collect only what's needed for stated purpose, delete after 90 days (Privacy satisfied—limits exposure) +- **Differential privacy**: Aggregate data for analytics, never expose individual records (Security satisfied—no breach risk) + +**Principle**: Regulatory constraints are non-negotiable.

Team Topologies Framework + +### Four Fundamental Team Types + +**1. Stream-Aligned Teams** (Product/Feature Teams) +- **Purpose**: Aligned with flow of business change (features, products, user journeys) +- **Characteristics**: Cross-functional, close to customer, fast flow +- **Size**: 5-9 people +- **Cognitive Load**: 1 product area, 1-2 user journeys +- **Example**: Checkout Team (owns entire checkout experience), Search Team, Recommendations Team + +**2. Platform Teams** (Internal Product Teams) +- **Purpose**: Reduce cognitive load of stream-aligned teams by providing internal services +- **Characteristics**: Treat stream-aligned teams as customers, self-service, clear SLAs +- **Size**: Larger (10-15 people) or multiple smaller platform teams +- **Examples**: Developer Experience Platform (CI/CD, testing frameworks), Data Platform (analytics, ML infrastructure), Infrastructure Platform (AWS, Kubernetes) + +**3. Enabling Teams** (Capability Building) +- **Purpose**: Build capability in stream-aligned teams (temporary, not permanent dependency) +- **Characteristics**: Coaches not doers, time-boxed engagements (3-6 months), transfer knowledge then leave +- **Size**: Small (2-5 people), specialists +- **Examples**: Security Enablement (teach teams secure coding), Accessibility Enablement, Performance Optimization Enablement + +**4. Complicated-Subsystem Teams** (Specialists) +- **Purpose**: Own complex subsystems requiring deep expertise +- **Characteristics**: Specialist knowledge, reduce cognitive load on stream teams +- **Size**: Small (3-8 people), domain experts +- **Examples**: ML/AI team, Video encoding team, Payment processing team, Cryptography team + +### Three Team Interaction Modes + +**1. Collaboration Mode** (High Interaction) +- **When**: Discovery, rapid innovation, solving novel problems +- **Duration**: Temporary (weeks to months) +- **Example**: Stream team collaborates with enabling team to learn new capability +- **Characteristics**: High overlap, pair programming, joint problem-solving +- **Warning**: Don't make permanent—high cognitive load + +**2. X-as-a-Service Mode** (Low Interaction) +- **When**: Clear interface, stable requirements, proven solution +- **Duration**: Permanent +- **Example**: Stream team consumes platform team's CI/CD service +- **Characteristics**: Self-service, clear SLA, API-first, minimal meetings +- **Goal**: Reduce cognitive load, enable autonomy + +**3. Facilitating Mode** (Temporary Support) +- **When**: Building new capability, unblocking stream team +- **Duration**: Time-boxed (weeks to months) +- **Example**: Enabling team teaches stream team performance testing +- **Characteristics**: Knowledge transfer, workshops, pairing, then exit +- **Goal**: Leave stream team self-sufficient + +### Team Topology Evolution + +**Stage 1: Single Team** (Startup, <10 people) +- One stream-aligned team owns everything +- No platform team yet (premature optimization) + +**Stage 2: Multiple Stream Teams** (Scale-up, 10-30 people) +- 2-4 stream-aligned teams +- Start seeing duplication (deployment, monitoring, data) +- Platform team emerges from common pain + +**Stage 3: Stream + Platform** (Growth, 30-100 people) +- 4-10 stream-aligned teams +- 1-2 platform teams (developer experience, data, infrastructure) +- Possibly 1 enabling team for critical capability gaps + +**Stage 4: Mature Topology** (Large, 100+ people) +- Many stream-aligned teams (organized by value stream) +- Multiple platform teams (federated platforms) +- Enabling teams for strategic capabilities +- Complicated-subsystem teams for deep specialties + +### Team API Design + +**Every team should document their "Team API":** + +1. **Code API**: What services/libraries do we provide?

Domain-Driven Design Alignment + +### Bounded Contexts & Team Boundaries + +**Principle**: Align team boundaries with bounded contexts (not just technical layers). + +**Bounded Context**: A conceptual boundary within which a domain model is consistent. Different contexts may have different models for same concept. + +**Example: E-commerce** +- **Shopping Context**: Product (SKU, description, price, inventory) +- **Fulfillment Context**: Product (tracking number, shipping address, delivery status) +- **Analytics Context**: Product (page views, conversion rate, revenue) + +**Same entity ("Product"), different models, different teams.** + +### Context Mapping Patterns + +**1. Partnership** (Two teams collaborate closely) +- Symmetric relationship, joint planning +- Example: Checkout team + Payment team for new payment flow + +**2. Shared Kernel** (Small shared code/data) +- Minimal shared model, high coordination cost +- Example: Shared customer ID schema across all teams +- Warning: Keep tiny—big shared kernels become bottlenecks + +**3. Customer-Supplier** (Upstream provides to Downstream) +- Asymmetric relationship, SLA-based +- Example: User Auth service (upstream) provides to all product teams (downstream) +- Supplier responsible for meeting customer needs + +**4. Conformist** (Downstream conforms to Upstream) +- Downstream has no influence on upstream +- Example: Product teams conform to external payment provider API +- Necessary when integrating third-party services + +**5. Anti-Corruption Layer** (Translation Layer) +- Protect your model from external complexity +- Example: Wrapper around legacy system to present clean API +- Use when upstream is messy but you can't change it + +**6. Separate Ways** (No integration) +- Contexts too different to integrate economically +- Example: HR system and product analytics—no overlap + +### Team-to-Context Alignment + +**Rule**: One team per bounded context (ideally). + +**Options if context too large for one team:** +1. **Split context**: Find natural seam within bounded context +2. **Multiple teams share**: Requires tight coordination (expensive) +3. **Sub-teams within**: Maintain as one logical team, sub-teams for focus areas + +**Options if team owns multiple contexts:** +1. **OK if contexts small** and tightly related +2. **Watch cognitive load**: Max 2-3 simple contexts per team + +--- + +## 4.

(efficient communicators) + +**Application:** +- **High betweenness**: Critical bridges—if they leave or resist, networks fragment +- **High degree**: Opinion leaders—influence many directly +- **Low centrality but critical domain**: Hidden experts—engage directly + +### Coalition Building + +**For Major Organizational Change:** + +**Phase 1: Identify Minimum Winning Coalition** +- What's minimum set of stakeholders needed to approve change? +- Who has veto power? (must include) +- Who has high influence? (prioritize) + +**Phase 2: Address WIIFM (What's In It For Me)** +- For each coalition member: What do they gain from this change? +- If nothing: Can we adjust proposal to create gains? +- Document value proposition per stakeholder + +**Phase 3: Sequence Engagement** +- Start with champions (easy wins) +- Then bridges (access to networks) +- Then high-power neutrals (sway with champion support) +- Finally address blockers (after coalition established) + +**Phase 4: Manage Defection** +- Monitor for coalition members changing stance +- Regular check-ins, address concerns early +- Adjust proposal if needed to maintain coalition + +### Resistance Management + +**Kotter's 8-Step Change Model:** +1. Create urgency (burning platform) +2. Form guiding coalition (power + credibility) +3. Develop vision (clear future state) +4. Communicate vision (over-communicate 10x) +5. Empower action (remove obstacles) +6. Generate short-term wins (momentum) +7. Consolidate gains (don't declare victory early) +8.

What does analogy predict about target that we didn't already know? +2. Is prediction testable? +3. If tested, does it hold? + +**Example**: +- **Analogy**: "Immune system is like cybersecurity defense" +- **Source domain fact**: Immune system has "memory" (antibodies persist) +- **Prediction for target**: Cybersecurity should have "threat memory" (remember past attack signatures) +- **Test**: Implement threat signature database. Does it improve detection? (Yes → productive analogy) + +### Scope Limitation Test + +**Question**: Where does analogy break down? What doesn't transfer? + +**Critical**: Every analogy has limits.

Explicitly state "No" cases as limitations + +**Example**: +- **Analogy**: "Startup growth is like rocket launch" +- **Maps**: Escape velocity (critical early momentum), fuel burn (runway), trajectory (growth curve) +- **Breaks down**: Rockets don't pivot mid-flight, can't refuel in space, one-shot (not iterative) +- **Limitation**: "Analogy useful for early momentum needs, but breaks down for pivot/iteration/long-term sustainability aspects. Startups ARE iterative and can refuel (fundraise), unlike rockets." + +--- + +## 5. Common Pitfalls & How to Avoid + +| Pitfall | Description | How to Avoid | +|---------|-------------|--------------| +| **Surface Analogy** | Maps superficial features, not structure. "Both are blue" doesn't help. | Explicitly map relations, not attributes. Test: Does analogy work if you change objects? | +| **False Synthesis** | Forcing agreement where genuine conflict exists. | When sources disagree, state it clearly. Don't paper over conflicts. Provide meta-framework or state uncertainty. | +| **Cherry-Picking** | Selecting only sources/data that support pre-existing view. | Systematic source inclusion. Explicitly address disconfirming evidence. | +| **Analogy as Proof** | Treating analogy as evidence rather than illustration. | State clearly: "Analogies illustrate, don't prove." Use analogy for explanation, not argumentation. | +| **Overgeneralization** | One data point or source → sweeping pattern claim. | Require 3+ sources for pattern claim. Acknowledge n=1 as anecdote, not trend. | +| **Overextending Analogy** | Pushing analogy beyond where it holds. | Explicitly test scope limits. State where analogy breaks down. Know when to stop. | +| **Mixing Levels** | Confusing data (facts) with interpretation (analysis). | Clearly label what's observation vs interpretation. "Data shows X (fact). This suggests Y (interpretation)." | +| **Ignoring Disconfirming** | Dismissing sources that contradict synthesis. | Actively seek disconfirming evidence. Explain why disconfirming source doesn't invalidate (scope, quality) OR revise synthesis. | +| **Vague Mapping** | Unclear what corresponds to what in analogy. | Create explicit mapping table. "In source, X. In target, Y. X↔Y because [relation]." | +| **Single-Source Pattern** | Claiming pattern from one source. | Patterns require repetition across sources. One source = theme, not pattern. | + +### Synthesis Quality Checklist + +- [ ] All relevant sources included and documented +- [ ] Source quality assessed (not all sources equal) +- [ ] Themes identified with frequency counts (X/Y sources) +- [ ] Agreements clearly stated +- [ ] Conflicts explicitly addressed and resolved (or uncertainty stated) +- [ ] Patterns identified with evidence from 3+ sources +- [ ] New insights generated (synthesis adds value beyond summarizing) +- [ ] Evidence cited for claims +- [ ] Gaps and uncertainties acknowledged +- [ ] Conclusions proportional to evidence (not over-claiming) + +### Analogy Quality Checklist + +- [ ] Source domain familiar to audience +- [ ] Target domain clearly defined +- [ ] Structural mapping explicit (entities and relations mapped) +- [ ] Multiple relations map (systematicity) +- [ ] Generates new predictions (productivity) +- [ ] Limitations explicitly stated (where it breaks down) +- [ ] Not used as proof (illustrative only) +- [ ] Appropriate for goal (pragmatic centrality) +- [ ] Deep (relational) not surface (attribute-based) +- [ ] Doesn't overextend beyond valid scope + +--- + +## 6. Advanced Integration Techniques + +### Synthesis → Analogy Pipeline + +**Use case**: Synthesize complex findings, then use analogy to make accessible. + +**Process:** +1. **Synthesize** first: Identify patterns across sources +2. **Find familiar domain**: What domain does audience know that has similar structure? +3. **Map pattern**: Transfer synthesized pattern to familiar domain +4. **Explain**: Use analogy to make synthesis accessible + +**Example**: +- **Synthesis**: Analyzed 20 incident postmortems → Pattern: 80% involve config change + missing rollback. +- **Familiar domain**: Home renovation +- **Map**: Config change = renovation, Rollback = "undo" plan, Missing rollback = no plan B if renovation fails +- **Analogy**: "System configs are like home renovations. You can change layout (config), but without 'undo' plan (rollback), failed renovation leaves you homeless (broken system). Always have rollback plan." +- **Result**: Technical pattern accessible to non-technical stakeholders via home renovation analogy. + +### Multiple Analogies (Triangulation) + +**Use case**: Complex target needs multiple analogies, each illuminating different aspect. + +**Technique**: Use 2-3 analogies for same target, each mapping different facet. + +**Example - Explaining "Technical Debt":** + +**Analogy 1: Financial debt** +- Maps: Borrowing (quick hacks) → Interest (maintenance cost) → Compounding (code harder to change) +- **Illuminates**: Cost over time, eventually must pay back + +**Analogy 2: Tooth decay** +- Maps: Skipping brushing (skipping quality) → Cavity (bug) → Root canal (rewrite) +- **Illuminates**: Gradual degradation, early prevention cheaper than late fix + +**Analogy 3: Garden weeds** +- Maps: Weeds (bad code) → Spread (contagion) → Harder to remove when established +- **Illuminates**: Contagion aspect, importance of early removal + +**Together**: Three analogies illuminate cost accumulation (financial), gradual degradation (tooth), and contagion (weeds). More complete understanding than any single analogy. + +**Key Takeaway**: Advanced synthesis combines information rigorously (thematic analysis, conflict resolution, pattern identification). Advanced analogy maps relational structure systematically (structural mapping theory, systematicity, productivity testing). Together, they enable understanding complex systems, transferring knowledge across domains, and generating creative solutions. diff --git a/skills/synthesis-and-analogy/resources/template.md b/skills/synthesis-and-analogy/resources/template.md new file mode 100644 index 0000000..7585f6e --- /dev/null +++ b/skills/synthesis-and-analogy/resources/template.md @@ -0,0 +1,333 @@ +# Synthesis & Analogy Template + +## Workflow + +Copy this checklist and track your progress: + +``` +Synthesis & Analogy Template Progress: +- [ ] Step 1: Define goal and scope +- [ ] Step 2: Gather and organize sources/domains +- [ ] Step 3: Apply synthesis or analogy techniques +- [ ] Step 4: Extract insights and test validity +- [ ] Step 5: Document findings and validate quality +``` + +**Step 1**: Define goal - synthesis question or analogy purpose.

Advanced Audience Profiling + +### Expertise Calibration + +Don't assume binary (expert/novice). Use spectrum with markers. + +**Technical expertise scale (example):** +1. **Novice:** Never heard term, needs analogy +2. **Aware:** Heard term, vague idea, needs definition +3. **Familiar:** Uses term, understands concept, needs context for depth +4. **Proficient:** Applies concept, understands nuance, needs edge cases +5. **Expert:** Teaches concept, wants precision and caveats + +**Calibration technique:** +- Identify 3-5 key terms/concepts in source +- For each, estimate target's level (1-5) +- Average gives overall expertise level +- Translate accordingly: define at level 1-2, use at level 4-5 + +### Goal Profiling + +Understand not just role but specific goal for this content. + +**Questions:** +- **What decision does this inform?** (Approve budget? Choose approach? Understand impact?) +- **What action follows?** (Implement? Communicate to others? Monitor?) +- **What's the risk of misunderstanding?** (Costly mistake? Minor inefficiency?) +- **What's already known?** (Baseline context? Prior decisions?) + +**Example:** +- **Executive reading technical postmortem:** Decision = Approve prevention work? Risk = Under-invest or over-react. Needs: Severity, root cause category, cost to prevent, confidence it's fixed. +- **Engineer reading same postmortem:** Action = Implement prevention.

Translation Validation Techniques + +### Expert Review + +**Best practice:** Have source domain expert review translation for accuracy. + +**Process:** +1. Provide expert with: (a) Original source, (b) Translated version, (c) Target audience description +2. Ask: "Is the translation accurate for this audience? What's missing or wrong?" +3. Note: Experts often over-include detail. Push back: "Does target need this for their goal?" + +**If no expert available:** Self-review by reading translation and asking "would I stake my reputation on this being accurate?" + +### Target Audience Testing + +**Best practice:** Show translation to representative of target audience. + +**Process:** +1. Find someone matching target profile (expertise, role, context) +2. Give them translated version (NOT original) +3. Ask: "What's the main message? What should you do? Any confusion?" +4. If misunderstood: Identify where and revise + +**Red flags:** +- Target misses key point → Not emphasized enough +- Target asks "what does X mean?" → Jargon not explained +- Target takes wrong action → Implications unclear +- Target seems talked down to → Tone too simple + +### Back-Translation Test + +**Technique:** Translate back to source audience level. Does it match original semantics? + +**Process:** +1. Translate expert → novice +2. Now translate novice version → expert (what would expert infer?) +3. Compare re-expert-ified version to original +4. Gaps = semantic loss in simplification + +**Example:** +- Original (expert): "p95 latency reduced from 450ms to 120ms via query optimization" +- Translated (novice): "Pages load 3x faster after improving database" +- Back-translated (expert): "Response time improved ~3x via database optimization" +- **Lost:** Specific metric (p95), exact numbers (450→120), method (query optimization) +- **Preserved:** Magnitude (3x), category (database) +- **Decision:** Acceptable loss for novice? If they need to reproduce work, NO. If they just need to know it's fixed, YES. + +--- + +## 5. Common Failure Modes & Recovery + +### Semantic Drift + +**Symptom:** Translation becomes inaccurate through cumulative simplifications. + +**Example:** +- Fact: "Reduces risk by 30% if applied within 24 hours" +- Simplification 1: "Reduces risk by 30%" +- Simplification 2: "Reduces risk significantly" +- Simplification 3: "Helps reduce risk" +- **Drift:** Lost quantification (30%) and time constraint (24 hours). Now sounds like "maybe helps a bit." + +**Prevention:** +- After each simplification, check against original +- Preserve one level of quantification ("significant" = at least 20-40% range) +- Preserve critical constraints (time, conditions, scope) + +**Recovery:** If drift detected, re-anchor to source and re-translate with tighter constraints. + +### Audience Mismatch + +**Symptom:** Translation too technical or too simple for actual target. + +**Diagnosis:** +- Too technical: Target asks "what does X mean?" frequently, gives up reading +- Too simple: Target feels patronized, says "I know this, get to the point" + +**Recovery:** +1. Re-profile audience (was assumption wrong?) +2. Adjust one level up/down on expertise scale +3. Test with different target representative + +### Emphasis Inversion + +**Symptom:** Translation emphasizes what source cares about, not what target needs. + +**Example:** +- Source (engineer): Excited about elegant algorithm +- Translation for business: Leads with algorithm elegance +- Target (exec): Doesn't care about elegance, cares about ROI +- **Fix:** Lead with business impact, mention elegance as side note if at all + +**Prevention:** Before translating, list target's top 3 priorities. Ensure translation leads with those, not source's priorities. + +### False Simplification + +**Symptom:** Simplification introduces error, not just loss of detail. + +**Example:** +- Fact: "Correlation between X and Y (r=0.6, p<0.05)" +- Bad simplification: "X causes Y" +- **Error:** Correlation ≠ Causation + +**Prevention:** Distinguish: +- **Loss of precision** (OK if within acceptable range): "30.2%" → "about 30%" +- **Loss of nuance** (OK if caveat added): "Usually works" + footnote "except cases A, B" +- **Introduction of error** (NOT OK): Changing meaning, implying false causation, stating certainty when uncertain + +**Recovery:** If false simplification detected, revise to either: (a) Preserve accuracy with explanation, or (b) Escalate to source expert for help simplifying correctly. + +--- + +## 6.

Advanced Chart Types + +**Small Multiples:** Same chart repeated in grid with consistent scales. Best for comparing metric across >4 categories. Max 12 charts; use consistent Y-scale. Example: Revenue trend for 12 product lines in 3x4 grid. + +**Sparklines:** Tiny inline charts in tables (no axes). Shows trend shape at a glance. Example: Table with "Trend" column showing ▁▂▃▅▆▇█ for each product. + +**Horizon Chart:** Space-efficient time series using color intensity layers instead of Y-height. For 20+ metrics in limited space. + +**Connected Scatter:** Scatter plot with points connected in time order. Shows X-Y relationship evolving. Example: Revenue vs Profit by quarter (Q1→Q2→Q3→Q4). + +**Hexbin:** Dense scatter (1000s+ points) using hexagon grid colored by density. Avoids overlapping dots. + +**Alluvial Diagram:** Flow between states over time. Bands show entity movement. Example: User tier transitions (Free→Pro→Enterprise) across quarters. + +--- + +## 3. Multivariate Visualization Techniques + +**Scatter Plot Matrix (SPLOM):** N×N grid of scatter plots for 3-5 numerical variables. Each cell = relationship between row/column variable. Example: 4 variables (MRR, Churn, CAC, LTV) = 4×4 grid. + +**Parallel Coordinates:** Vertical axes for each variable, entities as lines connecting values. Compare 20+ entities across 5-15 dimensions. Brush/filter one axis to highlight lines. + +**Heatmap Matrix:** Rows × Columns = Categories, cell color = metric. Example: Features × Segments, color = usage %. Use sequential (light→dark) or diverging (blue→white→red) scales. Sort by similarity to reveal patterns. + +**Bubble Chart:** 4D (X, Y, size, color). Example: Products (X: revenue, Y: margin, size: customers, color: category). Limit to <20 bubbles; label them. + +--- + +## 4. Statistical Overlays + +**Regression Lines:** Linear/log/polynomial trend in scatter. Annotate R²: "R² = 0.85 (strong correlation)". Distinct color from points. + +**Confidence Intervals:** Shaded band (forecast uncertainty) or error bars (mean ± SE). Example: 95% CI band around forecast line. + +**Distribution Overlays:** Histogram + normal curve (actual vs expected), Box plot + strip plot (quartiles + individual points). + +--- + +## 5. Geographic Visualization + +**Choropleth:** Filled regions (states/countries) colored by metric. Sequential (light→dark) or diverging (blue→white→red) scales. Pitfall: Large areas dominate; fix with cartogram or bubble map. + +**Bubble Map:** Precise locations with size = metric, color = category. Limit <100 bubbles; use clustering for density. + +**Flow Map:** Origin-destination lines, width = volume. For shipping, migration, traffic flows. + +--- + +## 6. Hierarchical & Network Visualization + +**Treemap:** Nested rectangles, size = metric, nesting = hierarchy levels. Click to drill down. Example: Revenue by category → product. + +**Sunburst:** Radial treemap (center = root, rings = levels). More compact for deep hierarchies (4+ levels). + +**Dendrogram:** Tree diagram for clustering/hierarchy. Example: Customer segmentation tree. + +**Network Graph:** Nodes & edges for relationships. Force-directed (organic clustering) or hierarchical (directed A→B→C) layout. Limit <100 nodes; node size = importance, edge width = strength. + +--- + +## 7. Color Theory & Accessibility + +### Color Scales + +**Sequential (Single Hue):** Light blue → Dark blue +- For: One metric, low to high +- Examples: Revenue, count, usage + +**Diverging (Two Hues):** Blue → White → Red +- For: Metric with meaningful midpoint (zero, average, neutral) +- Examples: Profit/loss, vs target, sentiment + +**Categorical (Distinct Hues):** Blue, Orange, Green, Purple +- For: Discrete categories with no order +- Limit: 5-7 colors (more requires legend lookup) + +### Colorblind-Safe Palettes + +**Common types:** +- Red-green colorblindness (8% of men) +- Blue-yellow colorblindness (rare) + +**Safe combinations:** +- Blue + Orange (most common alternative) +- Blue + Red (okay) +- Avoid: Red + Green alone + +**Tools:** Use simulators (Color Oracle) to test designs + +### Accessibility Checklist + +- [ ] Color contrast ≥4.5:1 for text (WCAG AA) +- [ ] Don't rely on color alone (add patterns, labels, shapes) +- [ ] Alt text describes insight ("Revenue grew 30%, driven by Enterprise") +- [ ] Interactive charts keyboard-navigable (tab, arrow keys) +- [ ] Legends positioned near data (reduce eye movement) + +--- + +## 8. Interactive Visualization Patterns + +**Filtering:** Dropdown (select one), multi-select (check multiple), date slider (range), cross-filter (click element filters other charts). + +**Drill-Down:** Click element to see breakdown. Breadcrumb navigation (Revenue > Product A > Feature X). + +**Tooltip:** Hover detail (exact value, context, metadata). Position near cursor, contrasting background, 2-4 lines max. + +**Brushing & Linking:** Select range on one chart updates others. Reveals cross-chart patterns. + +--- + +## 9. Animation & Temporal Visualization + +### Animated Transitions + +**When:** Show change over time (especially for presentations) + +**Example:** Bar chart race (ranks change month-by-month) + +**Best practices:** +- Pause controls (don't force auto-play through) +- Slow enough to follow (1-2 seconds per frame) +- Label current time period prominently + +### Before/After Comparison + +**Slope chart:** Show change for each entity +- Left: Before values +- Right: After values +- Lines connect (slope = change) + +**Dumbbell chart:** Like slope but horizontal +- Good for long category names + +--- + +## 10.

Adverbs (-ly words) + +**Before:** "He walked very slowly across the room." +**After:** "He shuffled across the room." +**Analysis:** "Shuffled" conveys slow walking more precisely than "walked very slowly." + +**Before:** "The data clearly shows that..." +**After:** "The data shows that..." +**Analysis:** If the data shows it, it's already clear. "Clearly" adds nothing. + +**Before:** "She was extremely tired after the race." +**After:** "She was exhausted after the race." +**Analysis:** "Exhausted" is stronger than "extremely tired." + +#### 2. Qualifiers + +**Before:** "This is somewhat concerning for our project." +**After:** "This is concerning for our project." +**Analysis:** Either it's concerning or it isn't. "Somewhat" hedges unnecessarily. + +**Before:** "The results were quite impressive." +**After:** "The results were impressive." +**Analysis:** "Quite" dilutes impact. + +**Qualifier words to eliminate:** +- very, really, quite, rather, somewhat, fairly +- kind of, sort of, type of +- just, actually, basically, essentially + +#### 3. Passive Voice + +**Before:** "The report was written by the committee." +**After:** "The committee wrote the report." +**Analysis:** Active voice is direct and clear. Actors act. + +**Before:** "Mistakes were made in the analysis." +**After:** "We made mistakes in the analysis." +**Analysis:** Passive voice obscures responsibility. Active voice is honest. + +**Before:** "The system is being upgraded by our team." +**After:** "Our team is upgrading the system." +**Analysis:** Active voice creates energy and clarity. + +#### 4. Weak Verbs + +**Before:** "There are three reasons why this is important." +**After:** "Three reasons make this important." +**Analysis:** "Are" is weak. Find the real verb. + +**Before:** "The storm had an impact on our schedule." +**After:** "The storm delayed our schedule." +**Analysis:** "Had an impact on" is bureaucratic. "Delayed" is direct. + +**Before:** "We will make a decision about the proposal." +**After:** "We will decide about the proposal." +**Analysis:** "Make a decision" → "decide" + +#### 5. Throat-Clearing + +**Before:** "It should be noted that there are several factors to consider in this situation." +**After:** "We must consider several factors." +**Analysis:** Cut the wind-up, get to the point. + +**Before:** "In my personal opinion, I believe that..." +**After:** "I believe that..." +**Analysis:** All opinions are personal. All beliefs are "I believe." + +**Before:** "At this point in time, we are currently experiencing..." +**After:** "We are experiencing..." +**Analysis:** "At this point in time" and "currently" both mean "now." + +### Complete Example: Pass 1 + +**Before (86 words):** +"In my opinion, the project that we have been working on is extremely important and really deserves to be given our full attention.

Reduce the mental work required to parse your sentences. Eliminate temporary ambiguities and improve coherence. + +### Techniques + +#### 1. Fix Garden-Path Sentences + +Garden-path sentences temporarily mislead readers, forcing them to backtrack and reparse. + +**Garden-path:** "The horse raced past the barn fell." +**Clear:** "The horse that was raced past the barn fell." +**Better:** "The horse fell after being raced past the barn." +**Analysis:** First version tricks readers into parsing "raced" as the main verb, forcing reparse when they hit "fell." + +**Garden-path:** "When Mary started to clean the kitchen smelled wonderful." +**Clear:** "The kitchen smelled wonderful when Mary started to clean." +**Analysis:** First version makes readers think Mary is cleaning the kitchen, then forces reinterpretation when they hit "smelled." + +**Garden-path:** "The students who the teacher had criticized harshly filed complaints." +**Clear:** "The students filed complaints. The teacher had criticized them harshly." +**Analysis:** Simplified to two sentences - easier to process. + +#### 2. Signal Topic Early + +Lead with what the sentence is about. Don't bury the topic. + +**Buried topic:** "In the report that was submitted yesterday by the research team, several critical issues were identified." +**Topic early:** "The research team identified several critical issues in yesterday's report." +**Analysis:** "Research team" is the topic - lead with it. + +**Buried topic:** "Among the many factors contributing to the project's success, effective communication stands out." +**Topic early:** "Effective communication contributed most to the project's success." +**Analysis:** Get to "effective communication" immediately. + +#### 3. Keep Subject-Verb-Object Close + +Don't insert long clauses between key sentence elements. + +**Distant:** "The report that the committee spent three months preparing based on extensive research and stakeholder feedback finally arrived yesterday." +**Close:** "The report finally arrived yesterday. The committee spent three months preparing it, basing it on extensive research and stakeholder feedback." +**Analysis:** Breaking into two sentences keeps elements close. + +**Distant:** "The developer who had been working on the feature for weeks despite numerous setbacks completed it." +**Close:** "The developer completed the feature. She had worked on it for weeks despite setbacks." +**Analysis:** Subject-verb separation causes cognitive load. + +#### 4. Ensure Pronoun Clarity + +Make sure every pronoun has one clear antecedent. + +**Ambiguous:** "John told Mark that he needed to revise his proposal." +**Clear:** "John told Mark, 'You need to revise your proposal.'" +**Or:** "John told Mark to revise the proposal." +**Analysis:** "He" and "his" could refer to either John or Mark. + +**Ambiguous:** "The team reviewed the code and the documentation. It had several errors." +**Clear:** "The team reviewed the code and the documentation. The code had several errors." +**Analysis:** "It" is ambiguous - what had errors? + +#### 5. Map Topic Chains + +Ensure each sentence connects to the previous one. Readers follow topics through a piece. + +**Broken chain:** +"Mozart was a prolific composer. Austria produced many famous musicians. The classical period saw great innovation." + +**Coherent chain:** +"Mozart was a prolific composer. His works span every genre of his time. The operas, particularly, show his genius." + +**Analysis:** Second version maintains topic: Mozart → His works → The operas + +### Complete Example: Pass 2 + +**Before (after Pass 1):** +"This project is important and deserves our full attention. We must consider several factors. The budget exceeded 20% - concerning. Similar projects show this pattern. We must get back on track quickly." + +**After Pass 2 (improved readability):** +"This project deserves our full attention. Three factors require consideration: budget, timeline, and quality. Our budget exceeded 20% - a concerning pattern shown in similar projects. We must get back on track." + +**What Changed:** +- Topic signaling: Made each sentence topic clear +- Concrete details: "Three factors" more specific than "several" +- Coherence: Connected "budget" across sentences +- Combined last two sentences for better flow + +--- + +## Pass 3: Improve Rhythm (Clark) + +### Goal + +Create engaging flow through sentence variety. Add gold-coin moments. End sentences with strong words. + +### Techniques + +#### 1. Vary Sentence Length + +Monotonous rhythm disengages readers. Mix short, medium, and long sentences. + +**Monotonous (all ~15 words):** +"The team completed the project on schedule. The results exceeded our expectations significantly. We learned valuable lessons from the experience. Our clients expressed satisfaction with the outcome." + +**Varied:** +"The team completed the project on schedule. The results exceeded our expectations. We learned valuable lessons - about collaboration, about time management, about quality. Our clients were delighted." + +**Analysis:** Added a very short sentence ("The results exceeded our expectations"), a longer complex sentence, and ended with impact. + +#### 2. Power of the Short Sentence + +After several longer sentences, a short one creates emphasis. + +**Example:** +"We reviewed the data carefully, analyzing trends over the past five years and comparing our performance to industry benchmarks. We consulted experts. We ran simulations. The conclusion was inescapable: we needed to pivot our strategy immediately." + +**Analysis:** "We consulted experts. We ran simulations." - short sentences build momentum toward the conclusion. + +#### 3. End Sentences with Strong Words + +The last word carries weight. + +**Weak ending:** "This is something we should think about carefully." +**Strong ending:** "This demands careful thought." +**Analysis:** Ends with the noun "thought" (strong) vs. adverb "carefully" (weak). + +**Weak ending:** "The storm was approaching rapidly." +**Strong ending:** "The storm approached." +**Analysis:** "Approached" is stronger than "rapidly." + +**Weak ending:** "Revenue increased significantly last quarter." +**Strong ending:** "Last quarter, revenue soared." +**Analysis:** "Soared" is more vivid than "increased significantly." + +#### 4. Gold-Coin Moments + +Place rewards throughout to keep readers engaged. + +**Gold coins include:** +- Surprising facts +- Good quotes +- Vivid examples +- Humor +- Beautiful metaphors +- Fresh insights +- Anecdotes +- Intriguing details + +**Strategy:** Don't front-load all your best material. Distribute it evenly, especially in the middle section. + +**Example:** +Instead of: [All good examples in opening paragraph] +Better: Opening example → mid-section surprising fact → closing anecdote + +#### 5.

The project timeline has been considerably extended beyond what was originally planned, and we are currently experiencing budget overruns that are quite substantial and concerning. In my personal opinion, based on my experience with similar projects, I really think that we need to very carefully reconsider our approach and make some important changes to how we're managing things going forward. There are basically three main areas where improvements could potentially be made. First of all, the communication between the various teams involved in the project has been somewhat lacking and could definitely be improved significantly. Secondly, the scope of the project seems to have expanded quite a bit from what was initially agreed upon, which has obviously had an impact on both our timeline and our budget. Thirdly, and perhaps most importantly in my view, we haven't been doing a very good job of tracking our progress and identifying problems early enough to actually do something about them before they become major issues. If we want to successfully complete this project and deliver results that meet our stakeholders' expectations, we really need to take immediate action to address these concerns and get things back on track." + +**After Pass 1 - Cut Clutter (155 words, 38% reduction):** +"Several significant issues need attention regarding our software development project.

Vivid Details + +**Details That Ring True:** +Specific, concrete details create credibility even without statistics. + +**Example:** +"The old mechanic had grease under his fingernails that no amount of washing would remove, and he smelled like motor oil and coffee." +- Specific details (grease, fingernails, smell) +- Rings true to anyone who's met a mechanic +- No statistics needed + +### The Sinatra Test + +"If I can make it there, I can make it anywhere." + +If you pass the toughest test, you must be good. + +**Examples:** +- Security system used by Fort Knox +- Accounting firm that audits the Fed +- Consultant hired by Google + +If they trust you, everyone should. + +### Application Questions + +- [ ] Why should readers believe this? +- [ ] Can I add a statistic (human-scale)? +- [ ] Can readers test this themselves? +- [ ] Do I have authority or compelling anti-authority? +- [ ] Have I included vivid details that ring true? +- [ ] Does it pass a Sinatra Test? + +### Common Mistakes + +❌ Using statistics too big to grasp (billions, trillions) +❌ Relying only on authority without evidence +❌ Making claims without support +❌ Using vague language instead of specific details +❌ Missing the "try it yourself" opportunity + +--- + +## E - Emotional + +### Principle + +Make people care. Appeal to identity, self-interest, or values. Focus on individuals, not masses. + +### Why It Works + +People act on emotions, then justify with logic. If they don't care, they won't act, no matter how logical your argument. + +### How to Make Them Care + +#### 1. Focus on Individuals, Not Masses + +**Mother Teresa's Principle:** +"If I look at the mass, I will never act. If I look at the one, I will." + +**Example:** +- Statistics: "2 million refugees displaced" +- Individual: "Meet Ahmed. He's 9. He walked 200 miles to safety, carrying his little sister." + +Which makes you care more? + +#### 2. Appeal to Identity + +**"This is who you are":** +Connect your message to readers' self-image. + +**Examples:** +- To developers: "You care about code quality. You take pride in your work." +- To parents: "You want the best for your children." +- To professionals: "You're not the kind of person who settles for mediocre." + +#### 3. Appeal to Self-Interest + +**"Here's what's in it for you":** +Show direct personal benefit. + +**Examples:** +- "Save 30 minutes every day" +- "Avoid the embarrassment of..." +- "Get promoted faster by..." + +#### 4. Appeal to Values + +**Tie to deeper principles:** +- Fairness +- Justice +- Freedom +- Security +- Family +- Achievement + +**Example:** +Not: "This policy affects many people." +Better: "This policy violates basic fairness - people doing the same work should get the same pay." + +### Real-World Example: Blue Eye/Brown Eye Exercise + +**The Lesson:** +Iowa teacher Jane Elliott wanted third-graders to understand prejudice after MLK's assassination. + +**What She Did:** +- Divided class by eye color +- Gave blue-eyed students privileges, treated brown-eyed poorly +- Next day, reversed it +- Students experienced discrimination firsthand + +**Why It Worked:** +- **Emotional:** Students felt the pain of discrimination +- **Personal:** It happened to them +- **Memorable:** They never forgot the lesson +- Not lecture (abstract) but experience (emotional) + +### WIIFY ("What's In It For You?") + +Always answer this question for readers: +- Why should I care? +- How does this affect me? +- What's the benefit to me personally? + +**Example:** +Not: "Our new process improves efficiency metrics." +Better: "You'll spend 30 minutes less in meetings each day. That's 2.5 hours a week - time you can use for actual work or leave early on Friday." + +### Application Questions + +- [ ] Why should readers care emotionally? +- [ ] Have I focused on one individual (not masses)? +- [ ] Does this appeal to their identity? +- [ ] Have I shown personal benefit (WIIFY)? +- [ ] Have I connected to values? +- [ ] Will readers feel something? + +### Common Mistakes + +❌ Focusing on statistics instead of individuals +❌ Missing the emotional core +❌ Appealing only to logic +❌ Not answering "What's in it for me?" +❌ Being too abstract or distant + +--- + +## S - Stories + +### Principle + +Use narrative to create mental simulation. Stories make readers experience ideas, not just understand them. + +### Why It Works + +When we read stories, we mentally simulate the experience. We put ourselves in the protagonist's shoes. We feel their emotions. We learn through vicarious experience. + +### The Three Plot Types + +#### 1. Challenge Plot + +**Structure:** Protagonist overcomes obstacles against the odds. + +**Emotional Takeaway:** "I can overcome my obstacles too." + +**Examples:** +- David vs. Goliath +- Startup competing with giants +- Person overcoming illness or hardship + +**Example:** +"Sarah joined the team knowing nothing about coding. For six months, she studied every night after work. She built small projects. She failed often. But she kept going. Today, Sarah is our lead developer. She deployed the feature that tripled our revenue." + +**What Readers Learn:** +Persistence pays off. They can do hard things. + +#### 2. Connection Plot + +**Structure:** Bridge a gap between people, groups, or ideas. + +**Emotional Takeaway:** "I can connect with others different from me." + +**Examples:** +- Unlikely friendships +- Cross-cultural understanding +- Bringing together opposing sides + +**Example:** +"The sales team and engineering team hated each other. Sales blamed engineering for bugs. Engineering blamed sales for impossible promises. Then we started monthly joint lunches. Just eating together. Talking as humans, not departments. Within three months, collaboration tripled. Within six months, they were finishing each other's sentences in meetings." + +**What Readers Learn:** +Connection is possible. Small bridges can heal big divides. + +#### 3. Creativity Plot + +**Structure:** Someone solves a problem in a new, creative way. + +**Emotional Takeaway:** "I can think differently and solve my problems." + +**Examples:** +- Innovation stories +- Lateral thinking +- Unconventional solutions + +**Example:** +"We spent months trying to make the app faster. Faster servers. Optimized code. Nothing worked enough. Then Maria asked: 'What if we don't make it faster? What if we make waiting feel faster?' She added a progress bar showing what the app was doing. User satisfaction doubled. Same speed, better experience. We were solving the wrong problem." + +**What Readers Learn:** +Reframe problems. Think creatively. + +### How to Use Stories + +**Show, Don't Tell:** +- Not: "Code reviews are important." +- Story: "Mark's code review caught a bug that would have crashed the system on Black Friday. 50,000 orders saved because Mark took ten minutes to review carefully." + +**Use Real Examples:** +- Real people (with permission, or anonymized) +- Real situations +- Real outcomes +- Specific details + +**Keep It Relevant:** +Story must serve the core message. Don't tell stories just for entertainment. + +### Application Questions + +- [ ] Have I included a specific narrative? +- [ ] Does it show a challenge, connection, or creativity? +- [ ] Can readers simulate the experience mentally? +- [ ] Does the story serve my core message? +- [ ] Is it concrete and specific? + +### Common Mistakes + +❌ Telling instead of showing +❌ Using hypotheticals instead of real stories +❌ Stories that don't serve the message +❌ Too vague or abstract +❌ Missing the human element + +--- + +## Stickiness Scorecard + +Rate your message on each element (0-3 points): + +### Simple +- 0 = Multiple competing ideas +- 1 = Core idea present but cluttered +- 2 = Clear core, mostly focused +- 3 = Single crystal-clear core (≤12 words) + +### Unexpected +- 0 = Completely predictable +- 1 = Mildly interesting +- 2 = Surprising or curiosity-inducing +- 3 = Violates schema AND creates curiosity gap + +### Concrete +- 0 = Mostly abstract +- 1 = Some specific examples +- 2 = Largely concrete and visualizable +- 3 = Fully sensory, specific, visualizable + +### Credible +- 0 = No evidence +- 1 = Weak support +- 2 = Good evidence (stats, authority, or details) +- 3 = Multiple credibility types OR testable + +### Emotional +- 0 = No emotional connection +- 1 = Slight appeal +- 2 = Clear personal benefit or value connection +- 3 = Strong identity, individual focus, or values + +### Stories +- 0 = No narrative +- 1 = Brief example +- 2 = Clear story with some detail +- 3 = Vivid story with mental simulation + +**Total Score: __/18** + +**Interpretation:** +- 15-18: Highly sticky message +- 12-14: Good stickiness, could improve weak elements +- 8-11: Moderate stickiness, needs work +- 0-7: Weak stickiness, major revision needed + +--- + +## Complete Example + +**Original Message (Weak):** +"Our new project management system offers improved efficiency and better collaboration features for teams." + +**SUCCESs Score: 3/18** +- Simple: 1 (vague core) +- Unexpected: 0 (predictable) +- Concrete: 0 (abstract) +- Credible: 0 (no evidence) +- Emotional: 0 (no personal benefit) +- Stories: 2 (brief example) + +**Revised Message (Strong):** +"You're wasting 10 hours a week in pointless meetings and searching for files [Unexpected, Concrete].
