This document discusses gauge repeatability and reproducibility (GR&R) studies, which are used to assess the reliability of measurement systems. It defines GR&R as a technique that uses analysis of variance to evaluate the repeatability and reproducibility of a measurement process. Repeatability refers to a gauge's ability to provide consistent results, while reproducibility captures variability from operators. The document outlines the benefits of GR&R studies, such as improving process understanding and identifying problems. It also provides examples of how to plan and conduct a proper GR&R study in five steps.
