I was asked this in an interview once.
Can Cp and Cpk be zero? If yes, what could this signify?
Thoughts?
PS: Based on the definition of Cp and Cpk, I suggested that you'd need infinite standard deviation (random process) or USL = LSL. The latter would suggest that the process in question doesn't have a range of specifications, but one target only. I never found out whether my answer was correct (didn't make it through the interview ).
