Measurement System Analysis (MSA)

Go Back

Definition

A procedure used to estimate the percentage of variation in a measurement that is due to the measurement system (gages, operators, fixtures) itself. The actual method employed depends on the nature of the measurements, whether they're continuous or attribute-based. Gage R&R (Repeatability and Reproducibility) is the name given to the MSA for continuous data.
