Verification by demonstration
Operating the item to show a function works, observed without the instrumented measurement a test records.
- the record it leaves
- a demonstration record with the observer, the configuration and the outcome
- read from
- a verification method cell reading “demonstration”, “demonstrations”, “demonstrate”, “demo”, “d”, “by demonstration” and “operational demonstration”
Whether demonstration is enough for a given requirement or safety rating is the assessor's judgement, and the finder never makes it. It reads whether a method is recorded and whether a verification is linked and passed: a blank method, or a method with no linked verification, raises finding 2.
