The Prioritisation Axiom: Testing needs a mechanism for ordering tests by value

Summary

Testers need to be able to rank tests in order of value and identify which tests are the most valuable.

Consequence if ignored or violated

Stakeholders do not get the evidence they require to make decisions because the necessary tests have not been executed in time.
