Process capability and Process Capability Index
Process capability is the ability of a process to produce output within specification limits. In process improvement efforts, the process capability index or process capability ratio is a statistical measure of process capability. The concept of process capability only holds meaning for processes that are in a state of statistical control. Process capability indices measure how much "natural variation" a process experiences relative to its specification limits and allows different processes to be compared with respect to how well an organization controls them.

Cp (Process Capability Index) estimates what the process is capable of producing if the process mean were to be centered between the specification limits. Assumes process output is approximately normally distributed.
Unfortunately, I cannot write you the formulas because of limitations in this writing tool, but you can find them online.
