RMP.9:4.4 - Retain or introduce the supported change

State what practitioners retain or change and the conditions under which the decision applies. Distinguish a semantic Method revision from a description correction, software repair or local deviation. A semantic change raises a variant question; previous qualification evidence applies only where its assumptions and reach still match.

For a selected change, make its consequences usable in actual practice. Supply the description, competence, tools or other support that is actually missing. Introduce it within the supported conditions, retain consequential provenance and recovery options, and distinguish its announcement, actual use and subsequent observed effects.

A team already capable of making a small correction does not automatically need a new training programme. A change with wider consequences may need substantial preparation and observation. Select later observation when it can expose a material failure or revise a live decision; do not turn every local repair into indefinite monitoring.

A Method retained for one situation may remain unsuitable for another. A justified branch names the situation discriminator and the evidence each variant can use. Do not turn an undocumented adaptation into a qualified variant simply by adopting a new name.
