PSDA.16:4.1 - 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 PSDA.15 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.

Use C.39.RP when the offered repertoire and its missing contributions need construction, C.39.RQ when the situated requirements for a Method need to be made explicit, and C.11.MV when a Method option’s worth is the unresolved comparison. Those Core Methods supply their general operations. The professional question here is which formulation, modelling, participation or return contribution can be offered under the actual engagement conditions, with the subject evidence and interpretation limits below.
