Require every small request to follow the heaviest change process available. This is too broad or manual for the stated objective.

Optimize a single team metric even when it reduces service value for users. This creates avoidable operational, security, or governance risk.

Apply the ITIL practice or guiding principle that improves value, collaboration, feedback, and controlled service outcomes without creating unnecessary process overhead. This directly supports measurable service health for the migration wave.
