Process capability indices (PCIs) have been frequently employed in manufacturing organizations. In this paper, some existing PCIs are reviewed, and after that, the loss function concept is used as a practical tool for PCI. In this regard, an effective scheme for a revised PCI is presented. The preference of the revised index is presented in theory and illustrated through a numerical example.
