B.5.1:1 - Problem Frame

Use this state model when a development project needs a shared account of whether a U.Episteme or U.System is being explored, shaped, evaluated or operated. The practical gain is to make the current development focus and the conditions for an intended transition visible. Without that distinction, a team may refine a design indefinitely or claim operational readiness before the required validation.

A development state describes the project’s treatment of its subject, not the assurance of every claim about it. A qualified explanation, proof or empirical result may already answer its receiving question while development remains in an earlier state. Ordinary use of that result needs no new development-state assignment.
