With the new MSA 3rd Edition, the changes included 'new method for analysis of Attribute measurement system', which is stated in Chapter III - Section C, page 125.
My question is that, do we really need to follow the new attribute GRR, as to show proof (to the auditors) that we are following the 'Hypothesis Test Analyses - Cross Tab Method', calculation of kappa, calculation of the effectiveness, miss rate and false alarm rate, and use the table of acceptance on page 132 ?
The old method, if I'm not mistaken is merely comparing any discrepancies in the attribute reading by two or more appraisers.
So, do I have to upgrade the methodology ?
