Description: For safety critical systems it's necessary for each requirement to be validated against a checklist. Satisfying each checklist item may require traceability to supporting artifacts that may be found in a variety of tools.

Stakeholder Roles: Program Manager, System Engineering Team, Requirements Engineers, Test Engineers, Fault Tree experts

Systems of Record: DOORS, Excel, MatLab

Key Artifacts: Requirements, Test Cases, Test Benches, Review Artifacts, Expert Opinions, Evidence of Rationale, Cross-reference tables

Link to related patterns: Knowledge Graph Pattern, Engineering Change Impact Traceability Pattern

Integration Solution: Implement OSLC Adapters for each relevant system so that the artifacts can be accessed and referenced in a standard way. Implement a centralized hub that manages the checklists and applies them to requirements extracted from third-party systems. Use proxy objects in the hub to normalize the data formats across systems. The hub manages the links between requirements, checklists, and the supporting artifacts for each checklist item. Navigate OSLC links to access more detailed information in each system of record.
