Verification Planning

Build an evidence path

Before changing a non-trivial system, build an evidence path: a project-specific route from the claim being made to evidence that can establish, limit, or refute it.

The purpose is not to select a familiar technique. The purpose is to decide how this system can reveal the truth of this particular change.

1. Frame the claim

State the behavior that needs to become true and the conditions that could make a confident conclusion wrong.

Consider what must change, what must remain true, where the behavior crosses a boundary, and which failure would matter most.
