Cpk
A process capability index that measures how well a process can produce output within specified limits, taking into account if the process is off-center.
TECHNICAL DEFINITION
Cpk (Process Capability Index) is a statistical measure of a process's actual capability to produce output within specification limits, considering both process variation and its centering relative to the specification midpoint.
BACKGROUND
Six Sigma (6σ) is a set of techniques and tools for process improvement. It was introduced by American engineer Bill Smith while working at Motorola in 1986.

USAGE NOTE
Cpk is generally preferred over Cp as it provides a more realistic assessment of process performance.
