In both cases we want to try to verify if the process can meet to meet Customer CTQs (requirements).Ĭp, and Cpk are used for Process Capability. Pp and Ppk are called Process Performance. What is the Difference between Cp, Cpk and Pp, PPk?Ĭp and Cpk are called Process Capability. Again, this will help me make the article better for you and everyone else. If you’re studying for something else, please leave a comment or contact me and let me know what you are studying for. This will help me make the article even better for you. If that’s you, leave me a comment below or contact me and let me know which organization and belt you’re studying for. This article was written to help Six Sigma Green Belt and Black Belt candidates prepare for and pass their exams. If you are not finding what you are looking for, please let me know in the notes below. There are also crib notes on what the equations mean in a real performance sense, what you should be able to tell about a process depending on Cp and Cpk values and more. This is a long article, but I thought it was important to keep Cp and Cpk together. In other words, it allows us to compare apple processes to orange processes! Process Capability In Six Sigma we want to describe processes quality in terms of sigma because this gives us an easy way to talk about how capable different processes are using a common mathematical framework. Cp and Cpk are considered short-term potential capability measures for a process.
