What is Meant by Cpk?
In statistics, Cpk is a Process Capability Index which is used to measure the ability of the process in order to produce the output for the customer specification. Cpk gives the best scenario for the existing process and helps to estimate the future performance of the process. In simple words, Cpk is a tool which is used to estimate the producer capability to produce a product for the customer specification. The formula to calculate Cpk is given by:
Cpk = Min [(USL- Mean)/3σ, (Mean-LSL)/3σ]
Where,
USL = Upper Specification Limit
LSL = Lower Specification Limit
