ME.20:4.3 - Localize a Situation Change
Compare the new fact with the claims and uses currently being relied on. Check applicability or preconditions; alternatives; constraints or interfaces; resources or capability; assignment, access, permission, or authority; evidence/currentness; expected result, stop, or risk; and the decision-relevant situation boundary. Inspect only positions whose possible change could alter the next result or action.
| What changed | What to reopen | What is not changed merely by this observation |
|---|---|---|
| A fact, evidence item, test outcome, or qualification window. | The affected result’s reliance/currentness and the current continuation judgement; obtain the first missing basis or stop. | The Method, completed Work, and an independently unchanged potential structure. |
| A claim supporting a proposed whole or a participant relation. | The exact ME.7 identity/composition question; ME.6 if the architecture alternatives or chosen arrangement are affected. Preserve individual ME.5 results whose basis still holds. | All participant identities or all source recovery merely because one relation is unresolved. |
| Reusable action, applicability, required contribution, permitted variation, or reidentification rule of a Method. | A.3.1/B.1.5 and the affected Method Engineering result, including ME.15 when variant identity is current. | Earlier performed Work or an automatic new description/publication edition. |
| A formal CGUS constituent, selected obtaining relation occurrence, applied constraint, or named use frame. | A.22 structure identity. A changed locus binding or potential-continuation row separately reopens CGUS membership. | A case judgement cannot silently stand in for the changed structure or membership test. |
| The instructions or intended-work content, with the represented Method still unchanged. | ME.8/ME.12 for description correction; A.15.2 for a changed WorkPlan. | Method identity or evidence that the planned action was performed. |
| The audience, relied-on claim, or publication/use boundary. | The affected representation, source-use, or publication question and its direct consumers. | Unaffected content or independently qualified uses. |
These are different change questions, not a universal event classification. For example, learning that evidence is missing does not prove that the claimed relation is false. If the reach of the change cannot be bounded, name that uncertainty and widen the relevant question; do not claim unaffectedness from the absence of a visible text edit.
