What is New Process Capability Index for Skewness about?

The document proposes a new process capability index, Cs, that extends an existing index Cpmk by incorporating a penalty for skewness. Cs is designed to help control skewness-prone processes like hole drilling, where increased mean, variance, and skewness indicate worsening capability. An estimator for Cs is proposed and shown via simulation to have comparable or lower variance than Cpmk, while being more responsive to changes in distribution shape. Cs is advocated for monitoring near-normal processes where
