Attribute data usually … WebCapability indices, Cp and Cpk, should be compared to one another to assess the differences over a period of time. The goal is to have a high Cp, and get the process centered so the Cpk increases and approaches Cp. The same applies for Pp and Ppk. Cpk and Ppk account for centering of the process among the midpoint of the specifications.
