WebIn a Six Sigma process, the Cpk equals 2.0. The Cpk is inversely proportional to the standard deviation, or variability, of a process. The higher the Cpk, the narrower the process distribution as compared with the specification limits, and the more uniform the product. As the standard deviation increases, the Cpk index decreases. 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. The Short Term Sigma (Zst) is the number …
