Overview for Nested Gage R&R Study

Use Nested Gage R&R Study to assess the variation in your measurement system when every operator cannot measure all parts.

For example, you have 3 operators and 15 parts. Operator A measures parts 1–5 twice, Operator B measures parts 6–10 twice, and Operator C measures parts 11–15 twice. Each part is unique to each operator; therefore, no operators measure the same part.
