Ppk is how the process did (long term). It is used to measure the performance of a system to meet customer needs. Use it when you want to measure a system’s actual process … WebIf Cpk is less than Cp and Cp is greater than one, center the process in the specification. This should make Cpk comparable to Cp. If Cp and Cpk are less than one, there are two actions you can take. The first (an unadvisable one) is to widen the specification particularly on the side that has the spec limit closest to the center of the process ...
