Process Capability (Cp & Cpk) - Six Sigma Study Guide

WebA process can have a Cp > 1.0 and produce no product or service within specifications. In addition, Cp values can't be calculated for one-sided specifications. A better measure of process capability is Cpk. Cpk takes into account where the process is centered. The value of Cpk is the minimum of two process capability indices. WebTherefore, Pp is high (1.80), and the overall capability of the process is good based on its variability. You can compare Pp to other values to get more information about the capability of your process. Compare Pp to a benchmark value to assess the overall capability of …

WebFeb 4, 2011 · Since the data was pulled from the entire "first run" population it was called Ppk. But it was in reality a short term process capability, or process (P)otential. When regular production started (i.e. unlimited population), the statistical studies could refer to Cpk, or process (C)apability. This is long term capability. WebCpk gives you the best-case scenario for the existing process. It can also estimate future process performance, assuming performance is consistent over time. Cpk is a standard index to state the capability of one process, the higher the Cpk value the better the process is. For instance, Machine 1 has a Cpk of 1.7 and machine 2 has a Cpk of 1.1.
