The traceability matrix connects every EMEP requirement to the component that implements it, the specification that defines it, the task that builds it, the test that validates it, and the KPI that measures it. Use this matrix to verify coverage, identify gaps, and track progress from requirement to delivery. ## Traceability chain Requirements flow through components, specifications, tasks, tests, and KPIs. Each link must be present for full coverage. ```mermaid theme={null} flowchart LR R[Requirement] --> C[Component] C --> S[Specification] S --> T[Task] T --> Te[Test] Te --> K[KPI] ``` ## Functional

If any cell is empty in a future revision, treat it as a coverage gap and create the missing artifact before the next phase gate.
