SYSE.21:10 - Rationale

C.36 supplies the transdisciplinary cultural-evolution distinctions. Systems Engineering adds a recurring domain decision: an engineering Method variant is worth continuing only in relation to configured project Work, integration, evidence, assurance, release, service, practitioner burden, and consequences for the project system-of-interest or other named affected Systems.

A Method can be described before it is enacted, and a project can create conditions for later enactment. Only later Work and cultural relations show which variant continued. Keeping project choice and distributed continuation separate supports both deliberate improvement and honest uncertainty.
