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

Requirements Analysis: Use feature traceability to understand requirement coverage
Architecture Review: Use component traceability to validate system structure
Interface Design: Use interface traceability for integration planning
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:

Review individual traceability documents for completeness
Validate mappings against source documentation
Update traceability data as system evolves
Use for impact analysis during changes
