PSD.15:4.1 - Bound the repertoire question by the work it must serve

Name the practitioner group or service using the repertoire, the recurring situation, the receiving decision-support result, and the horizon over which the offering matters. The starting question might be: “How can our engagements preserve a late but material participant correction without losing the ability to produce a timely qualified recommendation?”

Recover only conditions that can change the answer: disputed or already formed question; participants and power; access to affected parties; values and protected conditions; alternatives; uncertainty; available evidence; technical and facilitation capability; decision authority; receiving Work; and follow-up need.

Use a PSD.14 result only when its evidence can change this repertoire decision under the relevant configuration and horizon. A changed mobile-deployment premise may show that the existing follow-up Method worked by returning the correct blocker. It does not by itself demonstrate a defective Method. If a supplied result is missing, stale or incompatible, use a qualified direct account or name the precise gap.

Distinguish a missing input, a failure to enact the stated Method, a support or capability problem, and a defect in the reusable way itself. A practice cannot repair absent stakeholder access simply by adding another modelling technique. Conversely, more training cannot repair a Method rule that systematically excludes the required correction.
