2. Read for detail clarity. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
3. Read for verification. Keep the specific explanation in the respondent’s own words rather than converting it into an unexplained overall satisfaction score.
