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

Which field purpose was unclear?
What did you expect after submitting?
What information would help before requesting?

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: visitors cannot tell whether a request books a meeting.
2. Expected post-submission behavior exposes uncertainty about contact, scheduling or access following a demo request. State the actual process and conditions, without promising response times or availability that have not been verified.
3. Turn the requested improvement into a testable next step. One illustrative action is: explain the actual response and scheduling process.
