Welcome to the Cove Daisy
1) Yes - GP-12 is the procedure that descibes the Pre-launch Control Plan
2) Yes - The Pre-launch Control Plan (part of Delphi's Early Production Containment (EPC)) needs to be developed before the PPAP run.
3) Typically, No. At the time of PPAP, you have probably not run enough product to encompass all the special/assignable causes your process may exhibit. The "extra" controls in the Pre-launch Control Plan (larger sample size or increased frequency) should really stay in place long enough to show a "longer term" capability.
Hope that helps.
