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

What did the latest update explain?
What remained uncertain about the next step?
When would another update 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: updates acknowledge activity without explaining the next step.
2. Uncertainty about ownership, required customer action or the next update reveals different communication gaps. Separate these explanations when revising status notices; a clear message does not establish that the case progressed.
3. Turn the requested improvement into a testable next step. One illustrative action is: add next action and expected update timing.
