Cpk is … WebJan 27, 2024 · 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 .
WebIn a quality control context, PPM stands for the number of parts per million (cf. percent) that lie outside the tolerance limits. Cpk 1.00 means that 2 700 PPM (0.27%) of the manufactured parts are out of tolerance, while Cpk … WebCpk is a measure called the capability index. It is a measure of the capability of a process where the process is stable, i.e. we exclude any special, once off, unusual causes of variation, but do include routine common causes of variation. T he Cpk measure varies from 1 to 2 as follows: Cpk < 1.00 Process is not capable
