SYSE.2:4.5 - Expand only when another claim can change the candidate

The cheap first result is one linked use claim, one candidate concept claim, and their main uncertainty. Expand when further content—for example, another use situation, load, failure, participant, affected System, harm, benefit, or representation—could change the candidate. Add only the relevant:

  • environment structures and obtaining relations;
  • transformations, interactions, conditions, and effects;
  • functioning, interface, placement, resource, and constraint claims;
  • correspondence between a representation and the represented claims;
  • alternatives, assumptions, evidence limits, and specialist returns.

If source words such as operational system, system in operation, operations, or operational flow are current, distinguish two questions. Use this pattern for a System’s participation in use and the concept that supports it. Use Operations Management when the difficulty is managing continuing Work, queues, policies, or flows. An operational adjective does not settle that choice.
