SYSE.22:4.1 - Pattern-Use Unfolding

The Method uses eight recurring moves. They organize production of the account; problem-development, System-development, research, realization, integration, operation, and decision Work can overlap.

1. Decision boundary. The Agent identifies the actual System or intended-system designator selected as the project system-of-interest, or the System family and its membership and effectivity rules; current use, environment, affected Systems, configuration, horizon, resources, DecisionSubject, and authority complete the boundary.
2. Situation and problem records. The Agent separates the world-side occurrence or condition from assertions, observations, and evidence about it. Each selected ProblemCard states detection, problematic relation or unresolved claim, improvement check, constraints, affected Systems, evidence, receiving use, and the premises that make that evidence applicable. Include an expiry only where an actual qualification, right, resource or promised-use window ends; a review date alone does not invalidate the claim.
3. Archive and portfolio. Alternative formulations and weak signals remain in the archive under retention rules. The selected portfolio is finite and states why each record receives current attention or resources and what removes or reopens it.
4. System-family options. Actual Systems and configurations, candidate architectures, family membership and effectivity rules, and possible-future specifications are identified separately. Each option states what is realizable now and which builder or platform change it needs.
5. Problem–option correspondences. Every relied-on pair states the changed admission, comparison coordinate, protected characteristic, affected-System consequence, evidence need, or next action. A pair with no supported decision-bearing difference remains an unresolved mismatch.
6. Plural comparison. Archives, Fronts, and the decision OptionSet retain their own membership rules. The Agent compares several result and resource coordinates while retaining protected losses, uncertainty, and non-dominated alternatives. Do not force those coordinates into one scalar objective.
7. Choice or probe. The current OptionSet is fixed. The deciding Agent performs comparison-and-choice Work, applies C.11.CRC when a finite configuration-relative contribution comparison is needed, and applies C.11 to produce a decision result: a choice, tie-set, rejection, named probe, or reroute. The Agent selects a probe only when its expected contribution warrants its full burden: participant and engineering effort, delay, foregone alternatives and displaced protective Work as well as direct expenditure. The performer, resources, access, authority and useful observation window must be available. An affordable discriminator is not by itself a worthwhile probe; a useful qualified result may stand without new observations.
8. Later Work and selective reopening. Assigned Agents plan, authorize, perform, and interpret later Work through the applicable relations. New observations reopen only the problem records, correspondences, options, Fronts, configurations, or decisions that relied on the changed claim.
