Go To Top

Return to Relationship to Deployment, Testability, and Evidence Plan

Part 4 prepares implementation artefacts for Observation by defining the conventions and artefacts that expose implementation behaviour.

Observation preparation includes:

1. Node Status reporting
2. Lifecycle-state reporting
3. Startup reporting
4. Shutdown reporting
5. Warning reporting
6. Degraded-operation reporting
7. Failure reporting
8. Recovery reporting
9. Command acknowledgement
10. Processing outcome reporting
11. Logging conventions
12. Exception Handling conventions

Part 5 defines how the Phase 0 environment observes those behaviours during Deployment, execution, testing, and review.

Part 4 identifies the behaviour that implementation artefacts must expose. Part 5 defines the Observation approach used to collect, display, evaluate, and preserve that behaviour.
