Production Trial Run in AIAG APQP and Run at Rate (GP-9) GM 1927

Hello,

In AIAG APQP, the step 'Production Trial Run' is defined before PPAP. My understanding, before PPAP, the 'Production Trial Run' should be implemented or it can be considered that 'Production Trial Run' is a part of PPAP.

In GM 1927, the task 'Run @ Rate (GP-9)' is defined after PPAP. In GP-9 it states that "The Run @ Rate should be performed after the supplier has attained an acceptable PPAP submission and prior to start of production acceleration." So Run @ Rate should be implemented after PPAP.

So does it mean that for GM process there should be a step 'Production Trial Run' before PPAP, and a 'Run @ Rate' after PPAP?

Thanks

It means that APQP is a checklist and it also means that you could have reasons (with agreement from your customer) to skip certain steps in the APQP process.

So, if your GM SQE agrees with that a production trial run can wait until after PPAP, you are OK. (I doubt the SQE will).

Also understand this document:

If the production trial run is required before PPAP, is there any difference between the production trial run and GM's Run @ Rate considering the production rate, part amount or any other aspect?

Thanks,
