I.2.2.9.2 mass index, if applicable, the initial process studies should use or performance index ultimate expression CPK- stable process capability index. estimate σ is the (R-bar / d2 or S-bar / C4) PPK- performance index deteriorated subgroup within the determined basis. Σ value estimate based on the total variation of short-term studies (standard deviation of all the individual sample data (root mean square equation), "S" use). The initial aim is to understand the course of the study process variation PPAP, rather than reach a predetermined index value. When possible to obtain historical data or has enough initial data to a control chart when (at least 100 individual samples), CPK can be calculated when the process is stable. For output to meet regulatory requirements and showed a predictable wave, long-term instability in the process of using the PPK.

If there is no improvement before the start of mass production, we need to change the control plan. Index value <1.33 The process currently does not meet the acceptance criteria to meet customer requirements.
