WebProcess capability index (cpk) is used for calculating the ability of the process. The cpk formula is given as, Cpk = min [ (USL−mean)/3σ, (mean−LSL )/3σ] where, Cpk = Process capability index. mean = mean value. σ is a standard deviation. WebOct 10, 2024 · Cpk = min(USL-mean/3σ, mean-LSL/3σ) This means that Cpk is equal to the minimum value of these two calculations. For example, if USL-mean/3σ gives you 1.16 and mean-LSL/3σ gives you 1.25, your Cpk is going to be 1.16. That is because 1.16 is the lower of the two amounts and is therefore used as the minimum value.
