T here are three ways in which a standard costing system is typically used in a manufacturing company:

The Cp and Cpk are well-known capability indices commonly used to ensure that a process spread is as small as possible compared to the tolerance interval (Cp), or that it stays well within specifications (Cpk). Yet another type of capability index exists: the Cpm, which is much less known and used less frequently.
