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

Do you know where to submit an improvement idea?
How clear is the response after submission?
What would make the process easier to use?
What evidence would help a suggestion be evaluated?
How should decisions about suggestions be explained?

Author notes / illustrative keys where applicable:
1. Check whether the submission route is known before interpreting a low volume of suggestions as low interest.
2. Distinguish acknowledgement of receipt from explanation of what will happen next.
3. Identify one avoidable step in the process, without assuming employees want another submission channel.
4. Clarify what context helps evaluation while allowing early ideas that do not yet have numerical evidence.
5. Ask how outcomes should be explained so a rejected suggestion can still receive a useful, respectful response.
