SYSE.4:4.1 - Select one load-bearing claim and decision question

Start with one named claim episteme already used by a current engineering question. It may come, for example, from a project-system choice account, a linked use-and-system concept, a C.30 or C.32 architecture result, a SYSE.3 realization branch, or a specialist result. Recover:

  • the claim’s subject and predicate;
  • its scope, conditions, configuration or version, and temporal stance;
  • the result or source account from which the claim came;
  • the current uncertainty or failure mode; and
  • the decision or intended Work that would change if reliance narrows, stops, or becomes stronger.

A claim is load-bearing when the decision depends on it. The same claim may be load-bearing for one decision and incidental for another. Name the decision question before selecting a challenge; a generic wish to increase confidence does not yet select assurance Work.

The decision may still be contemplated. For a selected future challenge, record in the plan what result is meant to inform it. Establish any later decision occurrence, choice, gate passage, permission, acceptance, or release through its direct relation and evidence.
