I would like to know the difference - interms of methodology, formula between Preliminary process capability study PpK(widely used during PPAP submission in Automotive Industries), Capability Index Cpk & performance index Ppk.

How it is different from Short term capability & Long term capability studies being conducted during six sigma projects. Any relation???
