13.7 Traceability Requirements

Go to Top

1. The Conceptual Architecture SHALL define traceability across conceptual elements, logical elements, implementation artefacts, deployment artefacts, and evidence.
2. A Logical Architecture / PIM element SHALL trace to the conceptual element it specialises, refines, constrains, or relates.
3. An Implementation Profile / PSM artefact SHALL trace to the logical element it realises.
4. A Deployment Artefact SHALL trace to the implementation artefact it deploys, configures, executes, or exposes.
5. Evidence SHALL trace to the claim, behaviour, artefact, configuration, execution condition, review conclusion, or governance decision it supports.
6. Traceability SHALL support forward review from conceptual concern to evidence.
7. Traceability SHALL support backward review from evidence to conceptual concern.
8. Traceability SHALL support impact analysis across conceptual, logical, implementation, deployment, and evidence layers.
9. Traceability SHALL NOT require artificial one-to-one correspondence where one-to-many or many-to-one relationships better represent the architecture.
