Starting an MSA study - How to decide which is appropriate or required

[Calibrator24]

If I'm going to start an MSA study,

1. how would I decide what appropriate type of study is appropriate for my gauges?
2. Is it necessary or is it a requirement to conduct all the studies available(i.e. GR&R, Linearity, Bias, stability).
3. What if I miss one, am I not compliant to any standards?

Questions need to be reversed:

1. What are you trying to accomplish (e.g., why are you considering doing MSA?)?

2. What standards does your organization claim compliance to?

3. What types of gages are you studying?

An effective calibration system done right can address the bias and linearity aspects.

The need for stability studies depends heavily on the type of gages that you use. Gages and/or parts that are environmentally sensitive, or that might drift (like some electronic gages) should have a stability study performed.

Some type of R&R study is usually warranted unless you can group the gage into a family of gages that have already been evaluated.
