B.5.MPC:4.1 - Recover the physical difference the answer should resolve

Identify the thing or situation being understood or changed. Say which difference would make an answer useful: a displacement within a stated tolerance, the possibility of coupled rotation, a capacity bound during entry, or another consequence the work needs. Include the relevant boundary and operating conditions when changing them could change the answer.

Then recover what is already available. An engineer may have a trusted motion model but an unfamiliar command interface. A mathematician may have an odd-cycle theorem and ask which physical arrangements its obstruction describes. A room attendant may have a reliable card procedure and want to extend it to a second entrance. Enter through that available contribution and recover only the other results needed to answer the question.

Use B.5:4.1 when the question itself needs formation or revision. B.5.4 helps recognize the participants and relations of an explained concept in a concrete situation. If the receiving use is still unclear, work one small consequence of the available result and ask what it would let someone decide or do. Retain a theoretical question when its answer could enable a worthwhile construction, explanation or later inquiry.
