Webb12 apr. 2024 · Cp vs Cpk. The difference between Cp and Cpk is that Cp analyzes the ability of a process to justify the structured specification for a product. While Cpk portrays the deviation of a process from the center within the tolerance range. Cp is termed as Process Capability. Cpk is Process Capability Index. WebbThe capability is quantified by dimensionless indices that provide common and easy principles for evaluating the performance of a process. In calculating a process's capability index (s), the process must be in control statistically, i.e., the mean and standard deviation parameters are consistent all the time.
