The C_pk, more commonly known as the process capability index (Cpk), measures how well a process can produce items within specified limits. A Cpk of 1.000 indicates that the process mean is 3 standard deviations away from the nearest specification limit, which corresponds to a process capable of producing outputs within specifications 99.7% of the time, assuming a normal distribution.
