Requirements Traceability
The ability to map a requirement from specification through design, simulation, manufacturing, and field verification. Traceability matrix shows: requirement → design element that implements it → test case that validates it → manufacturing step that builds it → field instance that runs it.
Why it matters
Without traceability, engineers can't answer 'which design elements implement requirement X?' or 'if I change requirement Y, what breaks?' Traceability is the foundation of engineering change and risk management.
