====== P4-REQ-21-15-012 ====== [[dido:99_annexes:annex-d-requirements:part-04:start| Return to Requirements]] ===== Statement ===== The Part 5 handoff SHALL identify implementation traceability relationships. ===== Source ===== Part 4, Section 21.15: Part 5 Handoff Requirements. ===== Rationale ===== Part 5 must preserve the architectural justification for the implementation artifacts it deploys, tests, observes, operates, and evidences. Including implementation traceability relationships in the handoff allows Part 5 evidence and operational records to remain connected to the FX logical and implementation sources defined by Parts 3 and 4. ===== Applies To ===== This requirement applies to: * Node implementation traceability; * Topic implementation traceability; * IDL and generated type traceability; * Runtime Plane implementation traceability; * script and repository traceability; and * Developer Handbook traceability. ===== Verification ===== Verification SHALL confirm that the Part 5 handoff identifies applicable implementation traceability relationships. Verification activities should include review checks confirming that: * forward traceability remains available; * backward traceability remains available; * implementation artifacts retain their logical or implementation sources; and * Part 5 can preserve these relationships in later deployment and evidence records. ===== Traceability ===== This requirement carries the Part 4 Implementation Traceability Model into Part 5.
