Gage R&R
Gage Repeatability and Reproducibility, a statistical study used to evaluate the amount of variation in measurement data due to the measurement system itself.
TECHNICAL DEFINITION
Gage R&R (Gage Repeatability and Reproducibility) is a statistical analysis method used in metrology to quantify the variation contributed by a measurement system, differentiating between repeatability (variation within an appraiser) and reproducibility (variation between appraisers).
BACKGROUND
A measurement system analysis (MSA) is a thorough assessment of a measurement process, and typically includes a specially designed experiment that seeks to identify the components of variation in that measurement process. Just as processes that produce a product may vary, the process of obtaining measurements and data may also have variation and produce incorrect results. A measurement systems analysis evaluates the test method, measuring instruments, and the entire process of obtaining measurements to ensure the integrity of data used for analysis and to understand the implications of measurement error for decisions made about a product or process. Proper measurement system analysis is critical for producing a consistent product in manufacturing and when left uncontrolled can result in a drift of key parameters and unusable final products. MSA is also an important element of Six Sigma methodology and of other quality management systems. MSA analyzes the collection of equipment, operations, procedures, software and personnel that affects the assignment of a number to a measurement characteristic.
