Hello,

I would like to ask more experienced users about differences I noticed in R&R results. Our Supplier has been asked to present MSA results for their functional tester for PCBAs and it looks that on few testing steps R&R is higher than 30%. I have calculated sample results one more time in sample template found in Internet and my results are completely different. I would like to understand what is the reason of such inconsistency.

Please see attached my template with the results. According to the Supplier data, GRR/ANOVA is 2,37.

Thank you in advance!

I suspect that they are reporting the percent contribution while you are looking at the percent study variation. Your spreadsheet is fairly accurate.

See the analysis from Minitab.
