A delivery milestone is necessary, but it is not the same as an adopted change. People need clear responsibilities, useful documentation, workable exception paths and a way to report what the project team could not predict.
Plan the learning loop
Before release, decide which adoption signals matter, who will review them, and how feedback becomes prioritised work. Combine quantitative signals with conversations: low activity can indicate poor communication, missing access, a workflow mismatch or simply that the tool is not needed as often as assumed.
Benefits should remain connected to the original operational problem. That keeps post-launch work focused on value rather than activity alone.
