WebJan 27, 2024 · Process Capability Index and Controls. In Six Sigma, the Process Capability Index (Cpk) is a statistical tool used to measure the ability of a process to produce products within a client’s tolerance range. The higher the Cpk, the narrower the process distribution compared to the tolerance range, and the more uniform the output. WebThe process capability index is defined as the quotient between the length of the acceptance interval and six times the standard deviation obtained as a result of the design and production processes (Taguchi, Elsayed and Hsiang, 1989 ). The response should be made dimensionless by using the variables defined in (3.13).
