I’m going to go through an incredibly quick rundown of how to conduct your own Gage Repeatability and Reproducibility study using Minitab. The first thing you should keep in mind is that there are ways you “should” conduct a GR&R and there are ways you “shouldn’t”. You “should” be doing a blind, randomized study that doesn’t allow the “operator” to influence the study with what he expects. This isn’t always the easiest way to begin your first study or introduce yourself to these types of studies. For your first study, just do your trials in order.
