Traceability
Requirements Coverage
- System Requirements: All 45 SR-XXX requirements are covered by features
- Software Requirements: All 122 SWR-XXX requirements are mapped to features
- Components: All components are mapped to implementing features
Component Integration
Each feature document includes:
- Component Interaction Diagrams: Mermaid diagrams showing how components work together
- Interface Definitions: Clear specification of component interfaces
- Data Flow: How data flows between components within the feature
- State Dependencies: How the feature behaves in different system states
Usage
- For Requirements Analysis: Use feature documents to understand how requirements are implemented
- For Architecture Review: Use component mappings to understand system structure
- For Implementation Planning: Use component interfaces and interactions for development
- For Testing: Use feature behaviors and constraints for test case development
Document Standards
All feature documents follow:
- ISO/IEC/IEEE 29148:2018 requirements engineering standards
- Consistent formatting and structure
- Complete traceability to requirements
- Mermaid diagrams for visual representation
- Clear component interface specifications
Next Steps:
