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

Which role boundary was unclear?
What contact route did you understand?
What ending instruction was missing?

Author notes / illustrative keys where applicable:
1. Read for boundary meaning. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
2. Read for contact clarity. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for ending guidance. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
