Gage repeatability and reproducibility studies determine how much of your observed process variation is due to measurement system variation. Minitab provides two methods for Gage R&R Crossed: X and R, or ANOVA. The X and R method breaks down the overall variation into three categories: part-to-part, repeatability, and reproducibility. The ANOVA method goes one step further and breaks down reproducibility into its operator, and operator by part, components.

The ANOVA method is more accurate than the X and R method, in part, because it accounts for the Operator by Part interaction [8, 9].
