MMP.Preface:5 - Conformance Checklist - Can the result do its intended work?

For the combination being used, ask:

• What question does the result answer, and how will that answer be interpreted or used?
• What do the chosen mathematical objects represent? Which cases, operations and distinctions are retained or excluded?
• Which relations come from the subject, which follow mathematically, and which remain hypotheses or adjustable contributions?
• What operation obtains the answer, and what information or capability does its performer need?
• Do the connected contributions agree on the situation, timing, admissible variation and required consequence?
• Does a restriction, ambiguity or approximation still permit the proposed use? If the question changes, which part must be reconsidered?

A small use may already have these answers in one body and its worked argument. Carry that answer forward. Seek an additional check or observation when its result can change the decision enough to justify the cost, using C.11.DUA.
