Gage R&R Studies - Part that has 10-20 critical dimensions

Go/no-go gages are ideal for fit-type MMC true position tolerances. If the dimensions can be re-toleranced into a GD&T MMC True Position and make sense, then you would be on the right track. Another approach is to build the gages at 75% of the tolerance of non-critical dimensions to assure meeting final print requirements.

Question:

How do you conduct operator or equipment variation on a part that has 10-20 critical dimensions?

Do you select one dimension and have the operators measure one particular dimension?

Thanks
One method of clearing the smoke may be to develop a characteristics matrix on the common methods of inspection/gauge ..

Which dimensions use the same / similar equipment / holding method / appraiser / etc then to begin your analysis on the aspects that have the most commonality.
