WebThe process capability index, or process capability ratio, is a statistical measure of process capability: the ability of an engineering process to produce an output within specification limits. [1] The concept of process capability only holds meaning for processes that are in a state of statistical control. WebJan 27, 2024 · Cpk is calculated using the following formula, where UCL refers to the upper control limit and LCL refers to the lower control limit: Cpk = min(UCL - μ, μ - LCL) / (3σ) The higher the Cpk, the better (closer to 2.0 is excellent) where a Cpk of 1.33 essentially indicates the lowest value for a process that is in control and meets specification.
