PSD.15:5.3 - A source update and a cheap non-use

A new version of a relied-on methodological source changes the conditions under which a comparison procedure may be used. The practice identifies the exact applicability claim in its repertoire. The supported entry for complete input data remains; the incomplete-data branch is narrowed and its source question reopened. Other Methods that do not use that claim remain unchanged.

If the new source only changes layout or a locator while preserving the relied-on claims, update that description or access information under its direct guidance. If one current engagement simply needs an adequate existing Method, stop repertoire development and use PSD.6. Neither situation warrants a new professional Method.

A review reporting more published applications can justify looking for a promising candidate or an unexamined domain. It does not by itself change a local offering’s evidence or justify retiring a less frequently published Method.
