B.1.2:3 - Forces
| Force | Tension |
|---|
| Engineering concreteness vs broad FPF holon scope | System aggregation must be practical for systems without making all holons systems. |
| Delimitation vs external dependency | A named use needs an exact system boundary while critical relations can cross it and remain external. |
| Component structure vs functional structure | Physical or organizational bearers may realize several functions, and one function may require several bearers. |
| Conservative roll-up vs redundancy | Weakest-link and conservation checks are useful, but redundancy or substitution may require B.2 whole reidentification. |
| Description vs in-life system | Diagrams, BIM models, digital twins, and dashboards describe systems; they are not the system by appearance. |
| Coordination vs ownership | One decision may need many direct facts, but the coordinating pattern must not become the source of all those relations. |
