SYSE.6:9 - Consequences

Engineering contributors gain a current structural commitment that is strong enough to coordinate their Work and narrow enough to preserve local design knowledge. Accepted losses and unresolved residuals become visible. Realization, configuration, assurance, operation, and maintenance receive explicit questions and return conditions. The architecture can evolve through superseded decisions rather than through undocumented drift.

The cost is deliberate comparison and continuing maintenance of decision identity, descriptions, evidence, and effectivity. Some candidates remain open longer, and a preferred local solution can be rejected because it moves an unacceptable burden elsewhere. That cost is bounded by selecting only the project-shaping structures and the smallest evidence capable of changing the decision.
