IS.5:4.5 - Extend through changed conditions, not through a success label

A request to extend use starts with the new receiving work. Recover what is already the same and which differences can change applicability or provision. Differences can concern inputs, case distribution, authority, cost of error, available expertise, language, demand or access. Examine the differences that bear on the target operation or the support contribution; an arbitrary catalogue of site characteristics adds no assurance.

Reuse what remains sufficient. A shared explanation, common expert service or reusable exercise can serve several settings. Preserve a local contribution when it depends on the subject matter, available inputs or receiving judgement. For example, one service can maintain the comparison tool, while each technical practice retains its own criterion for whether a changed source defeats a claim.

A new location does not automatically need a full development programme. An equivalent use with adequate existing support may proceed directly. When a difference breaks a relied-on condition, obtain the needed adaptation or return to target selection. IS.2 and IS.3 supply those contributions; A.3.1.MI supplies a bounded introduction when that uncertainty warrants one.

Cultural continuation can require transmission beyond a service contract. Use C.36 to distinguish the needed carriers and transmission relations. Use C.36.RP when access, acquisition or provision must change to make a shared Method obtainable in the receiving setting. CB.14 supplies a joint repertoire undertaking when such work is wanted; its maintained result can also serve independent users. If a communicating community is itself needed, community practice supplies its relationships and maintenance. Do not invent a community requirement for people who can obtain and use the practice independently.
