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

How clear were responsibilities during implementation?
Which everyday task is ready to use?
What still needs support?
Was the handover documentation useful?
Who owns outstanding implementation actions?

Author notes / illustrative keys where applicable:
1. Check whether each party understood its responsibilities; a completed project plan does not prove operational ownership.
2. Use a real everyday task to distinguish usable delivery from configuration being marked complete.
3. Identify support still needed without requiring disclosure of internal customer documents or system credentials.
4. Ask whether handover material helped an actual task, rather than whether documentation was supplied.
5. Assign unresolved work to a clear owner so implementation does not end with an untracked list of issues.
