Definition of Cpk The equation for Cpk is more complicated: [minimum (mean - LSL, USL - mean)] / (0.5*NT). LSL stands for Lower Specification Limit and USL stands for Upper Specification Limit. WebIt is known that the higher the value of Cpk, the better is the process capability. A value that is less than 1, is considered incapable. A good process capability is something that falls between 1 and 1.33, where anything more than this is considered to be excellent and fulfills all requirements.
