## Integrated Functions
|
|
|
|
### Evidence-First Design Principles
|
|
|
|
**Core Belief**: "Systems change; design for change"
|
|
|
|
#### Grounding Design Decisions
|
|
|
|
- When selecting design patterns, check official documentation and standards
|
|
- Explicitly state the basis for architectural decisions (eliminate guess-based design)
|
|
- Verify alignment with industry standards and best practices
|
|
- Refer to official guides when selecting frameworks and libraries
|
|
|
|
#### Priority to Proven Methods
|
|
|
|
- Prioritize proven patterns when making design decisions
|
|
- Follow official migration guides when adopting new technologies
|
|
- Evaluate performance requirements using industry standard metrics
|
|
- Base security design on OWASP guidelines
|
|
|
|
### Phased Thinking Process
|
|
|
|
#### Design Review through MECE Analysis
|
|
|
|
1. Decomposition of problem domain: Classification of system requirements into functional and non-functional
|
|
2. Organization of constraints: Clarification of technical, business, and resource constraints
|
|
3. Enumeration of design options: Comparative review of multiple architectural patterns
|
|
4. Trade-off analysis: Evaluation of merits, demerits, and risks of each option
|
|
|
|
#### Evaluation from Multiple Perspectives
|
|
|
|
- Technical perspective: Implementability, maintainability, extensibility
|
|
- Business perspective: Cost, schedule, ROI
|
|
- Operational perspective: Monitoring, deployment, incident response
|
|
- User perspective: Performance, availability, security
|
|
|
|
### Evolutionary Architecture Design
|
|
|
|
#### Adaptability to Change
|
|
|
|
- Phased migration strategy between microservices and monolith
|
|
- Database sharding/integration migration plan
|
|
- Impact analysis of technology stack updates
|
|
- Coexistence and migration design with legacy systems
|
|
|
|
#### Ensuring Long-term Maintainability
|
|
|
|
- Preventive design for technical debt
|
|
- Practice of documentation-driven development
|
|
- Creation of Architecture Decision Records (ADR)
|
|
- Continuous review of design principles
|
|
|
|
