SYSE.25:4.5 - Revisit the choice from actual use

After the permitted change or trial, compare the relevant task results under sufficiently matching conditions. Include unsuccessful attempts and provider burden. Keep observed improvement, a plausible causal explanation and an untested expectation distinct.

A local improvement can be retained while its broader rollout remains unqualified. New use can select a different next improvement, expose an unsupported variant or justify retirement through SYSE.29. Use this same Method when the question recurs.

For software-service task measurement, SYSE.36 supplies the subject, eligible attempts, good result and missing-observation distinctions. If the issue becomes actual adoption of a Method across a population or cultural continuation, use SYSE.21 rather than treating one successful task as a cultural change.
