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

What origin did the description identify?
Which production stage was unclear?
What source reference was missing?

Author notes / illustrative keys where applicable:
1. Read for origin meaning. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
2. Read for stage distinction. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for source need. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
