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

1. For Requirements Analysis: Use feature documents to understand how requirements are implemented
2. For Architecture Review: Use component mappings to understand system structure
3. For Implementation Planning: Use component interfaces and interactions for development
4. 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:

1. Review individual feature documents for completeness
2. Validate component mappings against architecture
3. Ensure all requirements are properly traced
4. Update component specifications based on feature requirements
