## 7. Requirements Traceability
|
||||
|
||||
| Requirement ID | Epic | User Story | Test Case | Status |
|
||||
|---------------|------|------------|-----------|--------|
|
||||
| FR-UM-001 | Epic-001 | US-001 | TC-001 | {{STATUS}} |
|
||||
<!-- Example: FR-UM-001 (User Registration) | EP-1 User Management | US-1 Email signup | TC-1 Register with valid email | Implemented -->

## 8. Glossary
|
||||
|
||||
| Term | Definition |
|
||||
|------|------------|
|
||||
| {{TERM_1}} | {{DEFINITION_1}} |
|
||||
<!-- Example: SLA | Service Level Agreement - contractual uptime commitment (99.9%) | MTTR | Mean Time To Recovery - average time to restore service after failure | p95 | 95th percentile - 95% of requests faster than this value -->

||||
|
||||
**Update Triggers:**
|
||||

- [ ] All FR-XXX-NNN requirements have acceptance criteria
|
||||
- [ ] All FR-XXX-NNN requirements have MoSCoW priority (MUST/SHOULD/COULD/WON'T)
|
||||
- [ ] Traceability matrix links requirements to epics/stories
|
||||
- [ ] No orphaned requirements (all linked to business value)
|
||||
- [ ] All placeholders replaced with actual content
