+## 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
