B.1.2:8 - Consequences
Positive consequences:
- System aggregation remains practical for engineering systems and organizations.
- Boundary and interface concerns become explicit subject-pattern work without omnibus relation or check objects.
- Functional architecture, module allocation, and physical parthood stop collapsing into one diagram.
- Digital-twin and publication artifacts stay on the description side unless an exact stronger relation predicate is defined and current facts satisfy it.
Costs:
- Engineering diagrams used for decisions need annotations that name the exact relation and its defining pattern or declaration.
- Some familiar component lists must be split into physical parts, functional elements, external systems, sources, and descriptions.
- Whole-level characteristic claims need scale and relation discipline.
