    Hi Darth,
    Conceptually the Cpk used to predict the long term process behaviour as whether my process is capable for producing the product on long term basis. so you can’t predict on unstable process.
     
    ppk is attempting to answer does my current production sample meet specification, ppk is used where statistical control can not be evaluated.
     
    I hope this will help in clarifying twhat i meant.
    regards

    cpk is calculated where the process is under statistical control, and within subgroup variation  substantial,
     
    where ppk is calculated for the process which is not under the statistical control and total variation  of sample is taken for the calculation purpose
