IS.5:0 - Use This When

Use this pattern when an introduction has produced enough experience to decide what help should remain; when a helper, sponsor, tool or source is changing; when another setting wants to use the approach; or when the supported practice is no longer wanted or sufficiently useful.

Begin with one ordinary use that must remain possible and one actual dependency that may change. Find what currently enables that use, including help that is easy to overlook because an expert quietly supplies it. Then decide whether to retain, reduce, replace, transfer, extend or end that contribution. The useful result can be a continuing purchased service. Independence is not an obligatory maturity stage.

Do not run a sustainability project merely because a bounded attempt has finished. If continuing use and its support are already adequately provided, use that arrangement and its ordinary correction route. If no continued use is promised, settle the attempt’s actual remaining obligations and stop.
