## Traceability Scope

### Feature Traceability
- **Software Features:** All 10 software features (F-DAQ, F-DQC, F-COM, etc.)
- **System Features:** Mapping to original system feature groups
- **System Requirements:** Complete SR-XXX requirement coverage
- **Component Mapping:** Which components implement each feature

### Component Traceability
- **Components:** All system components and their responsibilities
- **Interfaces:** Public APIs and integration points
- **System Requirements:** Requirements implemented by each component
- **Software Features:** Features supported by each component

### Interface Traceability
- **Software Interfaces:** All public APIs and communication interfaces
- **Component Providers:** Which components provide each interface
- **Software Features:** Features that use each interface
- **System Requirements:** Requirements addressed by each interface

## Usage

1. **Requirements Analysis:** Use feature traceability to understand requirement coverage
2. **Architecture Review:** Use component traceability to validate system structure
3. **Interface Design:** Use interface traceability for integration planning
4. **Testing:** Use all traceability data for test case development

## Traceability Standards

All traceability documentation follows:
- ISO/IEC/IEEE 29148:2018 requirements engineering standards
- Complete bidirectional traceability
- Consistent ID formats and naming conventions
- Machine-readable CSV format for tool integration

**Next Steps:**
1. Review individual traceability documents for completeness
2. Validate mappings against source documentation
3. Update traceability data as system evolves
4. Use for impact analysis during changes
