C.39.RQ:10 - Rationale

A fit claim is bounded by a particular use, subject, situation, evidence basis, and time. Criteria are inputs to that later claim, not the claim itself. Returning every condition to its actual subject prevents a well-written description from standing in for capability, a provider arrangement from standing in for a Method, or one management view from standing in for the Work.

Method Content Theory and the design-method ecosystem line are complementary because they ask different source-side questions. This pattern connects situational criteria for Methods, Work, descriptions, capability, tools, culture and variants while keeping their subjects distinct. Project, process and case accounts can expose different requirements; their direct subjects determine where those requirements belong, whether the accounts concern one Work or several related subjects.
