Attributes Gage R&R
You must be carefull when selecting the method to do the attribute Gage R&R, there are two methods described in page 125:
A. Analytic Method
B. So call cross tab.
A method ont his page it says that is the most appropiate one (Right in the introduction paragraph).
B. method it says that requires customer approvals, so do not use the method that requires 50 samples (Cross Tab) unless you have approvals from all your automotive customers.
Analytical Method does not required approvals and it takes 8 samples only with one user, however it so confusing that in 3 months I have work on implementing it, so far I have not been able to understand, even after going to training for MSA implementation in Detroit to a company approved by AIAG.
