---- Please see 8-14b on the following link: http://www.math.wsu.edu/math/faculty/lih/10-11s.pdf; regarding your statement about Cpk, you say that, "Estimates what the process is capable of producing if the process target is centered between the specification limits." The word, NOT, should be added before the word centered and the word "target" needs to be replaced with the words estimator of process mean uhat or simply xbar. Cpk is calculated when the process mean is not centered. Do you agree? Jun 30 2011
