WebMar 26, 2016 · Generally, a CPK greater than 1.33 indicates that a process or characteristic is capable in the short term. Values less than 1.33 tell you that the variation is either too wide compared to the specification or that the location of the variation is offset from the center of the specification. It may be a combination of both width and location. WebCp, Process/Product Capability Index, is the relationship of the process/product variation to the upper and lower specification limits. Cp is not a measure of how centered the data is. Cp is used when there are two-sided specifications. Higher values of Cp are better. One of the goals under Six Sigma is a Cp of 2 or larger.
