Learn How to Calculate Pp & Ppk - Tutorial, Definition and Example Process Performance (Pp) Definition: Process Performance denotes whether a process is performing correctly in a certain period of time within the overall requirement. Pp is based on same equation as Cp with one exception; Pp employs the long term standard deviation (whereas Cp employs the short term standard deviation). Ppk is based on same equation as Cpk with one exception; Ppk employs the long term standard deviation (whereas Cpk employs the short term standard deviation). When to Use Pp, Ppk, Cp, and Cpk. The main difference between Pp and Cp on one side and Ppk and Cpk on the other side is whether we use complete set of data for calculation (Pp and Ppk) where we calculate real performance of the system, or we use sample (pre-production, batch, logical subgroups) where we calculate capability of the process.
