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.
In context
In an aerospace program, a safety requirement in DOORS is traced through the structural analysis in Nastran, the test case in Jama Connect ALM, and the manufacturing inspection step in the MES — so a change to the requirement immediately flags every downstream artifact that must be re-validated. Without this traceability, an approved engineering change can inadvertently invalidate a certification finding without anyone noticing until audit.
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.
