Re: %GRR <10% not possible. How to get approval by auditor?

Discussion has gone in wrong direction from beginning. There is something wrong with measuring method and that's the problem.
I would add to Miner's points about why 10%-30% is often OK that the formula for calculating this number is mathematically flawed and more often than not it overstates the measurement error contribution to the overall variation.is

Given that the characteristics that the OP is concerned with are those non-critical characteristics (they are not on the PPAP) this becomes even more important.
Thanks to Bev D for your informative Post and/or Attachment!
