ME.23:4.3 - Make each relation say something useful

Use the relation that changes the receiving action. The following are common questions, not a required universal relation catalogue:

Relationship questionUseful statement
Result dependencyThis description review consumes the qualification of these claims; if it is missing, return to that qualification.
AlternativeEither representation can serve this action under its stated loss limits; choosing one does not prove the other false.
Source supportThis assertion relies on this recovered passage for the named use; changed or unavailable basis reopens that reliance.
ConflictThese candidate conditions cannot both govern the same selected use; retain the conflict for the owning decision.
Reuse or specializationThis profile reuses the general action and adds this source-specific condition.
Method compositionThis independently admitted Method is a part of that whole under the B.1.5 result.
Publication groupingThese bodies are shown together to help discovery; their display order makes no stronger relation claim.

A formal CGUS is appropriate only when that structure is itself needed. A.22.CGUS supplies the constituents, selected obtaining relations, applied constraints and named use frame, as well as potential branching and case-judgement requirements. Plain alternatives and conditions do not automatically admit that structure. ME.20 supplies ordinary situated continuation and its optional formal branch.

A changed fact can change a continuation judgement under the same frame. A changed question, admissible action or stop can require reidentification. The user or capable system assesses the new situation. During ongoing Work, A.15.7 supplies the next-action decision.

When the promised use includes performing or learning a Method, show its relevant vertical as well as result dependencies. At a selected moment, what constituent action is enacting what encompassing work, and what changes in that action when a condition of the whole changes? B.1.5.EW supplies this recovery. Show the capability, support and combined resource conditions that the DPF’s own bodies leave to another contribution. Use a representative case where a missing intermediate performance changes the continuation; do not require an exhaustive stack when its understood parts cannot change the use. B.1.5.RS supplies the distinct comparison when a constituent is replaced across encompassing uses.
