# "within subgroup" or "potential" capability (Ppk is long term indicator) of a process assuming it was analyzed and stays in control. The formula is shown below:.

Ppk uses "s-long-term" to evaluate the behavior of the process. If the process is stable, Ppk = Cpk, i.e. the actual performance will match the predicted potential performance. However, if the process is unstable – i.e. if it shifts or drifts over time – you will find Ppk << Cpk.
