.....you show GRR% of less than 10%, most customers will accept the measurement system to be acceptable...unless there is a "pain in the ***" engineer (hate to say this but am one of them ) who reviews suppliers' results and asks questions.

Hey Qualeety - I wish we had people who looked at our PPAP submissions and asked good questions. It is sad to do all the work for MSA only to have someone "weigh" the submission to see if it is good enough.

For years I put negative Cpks and GRR of 100% in sumbmissions along with a note to contact me if there was a concern - no one ever called!

You keep on asking questions - I'd like to think what I do matters!

yah, i hear you...all the ppap requirements and quarterly spc chart submissions (not sure whether this is still being practiced?)...for what!!!! ...sometimes, you wonder...

Anyone works for Big Five and can tell us what you do with PPAP?...is there a written procedure of how to "review/approve PPAP"....

btw....Ford became 5th largest auto manufacturer in Canada....after GM, Chrysler, Honda and Toyota (see globeandmail.com)

In calculating GR&R, generally 90% is the limit. Is there a specific limit for 95% of UCL and LCL.
pls. advise.
