Are MSA’s (Measurement System Analysis) Process or Gage Based?
I’ve searched through all of the threads and have read the MSA book, but I can’t find a clear answer. The book would seem to indicate that it is process based, but all actual applications seem to be gage based. I am currently organizing our MSA’s. If they are process based then we would need an MSA for each process using a gage in the control plan. If they are gage based then we would need an MSA for each type of gage listed in our control plans and organize them according to gage types. Would an auditor ask for an MSA for calipers because they are listed in a control plan, or would an auditor ask for the MSA of a process (including GR&R of the calipers)?
I’m also interested on a personal level. If MSA’s are process based then it would be very useful although time consuming. If MSA’s are gage based then they are an absolute waste of time. There is no need to have an MSA for calipers (gage based). All good calipers on the face of the planet are going to perform the same. The only variation is going to be in the application they are used for (process based).
Any help will be appreciated.
