If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which change notice arrived too late?
What availability information was unclear?
What planning adjustment would help?

Author notes / illustrative keys where applicable:
1. Use this answer to locate the part of the experience that needs explanation. The example issue to investigate is: staff cannot identify the final published schedule.
2. Unclear availability context reveals whether the published rota distinguishes confirmed coverage from provisional information. Clarify the actual labels and update route, without collecting private schedules or interpreting availability as a staffing commitment.
3. Turn the requested improvement into a testable next step. One illustrative action is: use one clearly versioned schedule source.
