C.39:4.3.1 - Give the connection its actual relation

Select only the structures whose relations change the use; C.30.ASV:4.5a develops that selection. An ordinary explanation can suffice. Use A.22 when a stronger structure claim is needed.

• Result use and continuation. For a serial connection, show why a result supplies the next precondition. For parallel work, explain the relied-on independence and how results join, including simultaneous resource demands. For alternatives, state the distinguishing condition and what happens when it is unknown or none applies. For iteration, say what the last result changes and when another attempt is unwarranted. A fallback needs a recognizable trigger and a result still useful to the receiver. A.22.CGUS develops the question of currently possible continuations; its formal qualification is needed only for the stronger claim.
• Composition and enactment. Call the connected operations one Method when the proposed whole has its own reusable action, applicability, result and constituent relations under A.3.1 and B.1.5. When an actual action performs part of encompassing Work, B.1.5.EW recovers that relation and the whole’s constraints. Neither relation is just temporal order. A list of independently usable Methods can explain result uses without asserting one whole.
• Generality, variation and replacement. C.39.RO separates variable inputs from retained premises and develops a construction into an operation usable on another occasion. A permitted parameter change can remain a variation of one Method. Directed refinement between Methods additionally needs the comparison in A.3.1:4.7–4.8: participants, applicability, premises, action, intended result, constraints and acceptance conditions, with a stated direction and preserved meaning. A replacement also needs its affected uses and possible losses. Ordinary comparison suffices when no stronger identity or refinement claim is needed.
• Use across domains. A calculation, instrument model, observation method and access arrangement may support the same work. Explain the result each supplies and its conditions. That dependency neither makes one discipline a part of another nor assigns it a universal rank.

These relations can intersect. A calculation may constitute part of preparation while its result supports several independent uses. Name the relations separately. If a diagram calls them “vertical” and “horizontal”, state its orientation and represented relation under A.22:4.3a; the axes themselves supply no meaning. FPF, DPF and LPF name framework scope and basis, not a ready-made stack of Methods.
