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

What were you trying to inspect?
What did the fallback explain?
What alternative action was unclear?

Author notes / illustrative keys where applicable:
1. Read for inspection intent. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
2. Read for fallback comprehension. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for alternative action. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
