It is possible to have a process which is out of control but has a high value of Cp. Specification limits are established by managers, based on customers expectations Specification limits are computed using a formula in an ideal process we should have USL < UCL and LSL > LCL It is possible to have a process which is in control and yet has a very low Cp
