In Gage R&R; there are many experts including the AIAG source suggesting the short method (5 parts x 2 operators x 2 replicates) = 20; I don't think this is a statistically robust strategy. It maybe good enough as a starting point that will lead to a different Gage RR Strategy.
And there is also, the Long Method: (10 parts x 3 Operators x 3 Replicates) = 90. This sounds like a good strategy if you have the time/resources @ your disposal.
I am seeking your help & advice as what strategy would you follow, recommend, has worked for you in the past. In another word; what is the min # of parts, opertors, & replicate that you recommend.
Note: The study has to achive the objective of a Gage R&R study & to qualify the Gage, and be Statistically Robust & sound.
Any recommendations, guidance, a formula, a stratergt that have worked with you would be appreciated.
Thanks in advance
