Abstract

This article addresses the relationship between standard (manufacturing) measurement system analyses (MSA) and those encountered in the Service Quality/Transactional arena.

Notes

To perform a "Gage R&R" study in the transactional arena can present several unique issues, not typically addressed in more traditional MSA studies. The instance of "fudging" one or more datapoints to create an error term (otherwise the mean squared error would be zero i.e. there is no estimate of repeatability) is something I've come across frequently. As discussed in the paper, it's entirely inappropriate (rather difficult to persuade people of this in practice though, as statistical results are generated.)
