When a standard GR&R study is not enough, try an Expanded Gage R&R.
If you can’t trust your measurement system, you can’t trust the data it produces. That’s why Measurement Systems Analysis (MSA) is a key component of establishing, improving and maintaining quality systems. Whether you’re engaged in a Six Sigma project or an ISO9000 certification, an MSA helps you identify problems with your measurement system and determine if you can trust your data.
The most common type of MSA is the Gage repeatability and reproducibility (R&R) study. Most Gage R&R studies assess the effects of two factors on variation in your measurement system—typically operator and part.
