Cp, Cpk, Pp and Ppk

A guide to process capability
and capability indices

Are you looking for ways to improve the quality of your production process? Cp, Cpk, Pp, and Ppk are parameters (indices) that can serve as indicators for the performance and capability of your process. The value of Cpk or Ppk tells you how capable your process is at delivering a high-quality product.

Our whitepaper offers a guide to using these parameters and provides clarity on how to use and interpret them. We also show how smart QMS software can make your process more reliable.

Some key takeaways from the whitepaper include:

  • Cp, Cpk, Pp, and Ppk are parameters that can be used to measure the variability of your process and help manufacturers determine the performance and capability of their process.
  • Cp and Cpk are used with stable, mature processes that are under statistical control. In contrast, Pp and Ppk are useful when analyzing performance in a preproduction run or a new process that is not yet under statistical control.
  • AlisQI can help you easily determine the performance and capability of your process. The smart, intuitive system calculates the indices and creates visual snapshots, helping you establish process stability and make informed decisions.
