SYSE.7:10 - Rationale
FPF already gives general precision for the needed transdisciplinary objects and relations, including epistemes, descriptions, publications, views, reference schemes, representations, mathematical lenses, evidence, currentness, configurations, and Work.
Select a heterogeneous set of descriptions for the engineered-System decisions. Preserve subjects and configurations across functional, physical, behavioral, analytical, realization, and assurance uses. Expose conflicts between claims, connect candidate and intended descriptions to evidence from actual realization and operation, and turn gaps into questions for the engineering Work that can change the System or revise the decision.
The ensemble is decision-bounded because no description is complete for every use. The same plant can require different selected structures and representations for different uses—for example, control design, installation, maintenance, economic choice, safety assurance, or operator training. Choose and relate descriptions by the claims that must be jointly usable now.
