Process capability index mean is T, the estimated mean of the process is formula_1 and the estimated variability of the process (expressed as a standard deviation) is formula_2, then commonly accepted process capability indices include: formula_2 is estimated using the sample standard deviation.

Values near or below zero indicate processes operating off target (formula_1 far from T) or with high variation. Fixing values for minimum "acceptable" process capability targets is a matter of personal opinion, and what consensus exists varies by industry, facility, and the process under consideration. For
