Usage notes & scoring

CR = .85, AVE = .58. Adapted from Homburg (1998). 5-point strongly agree–strongly disagree scale. Two items are reverse-scored. Validated on combined US and German manufacturing sample (n=478). Study found higher quality unexpectedly lowered (not raised) direct product costs, consistent with quality-based learning curve arguments.
