What is a Process Capability Study?

Process Capability Study is a tool used to determine if a stable process is capable of meeting a customer’s specification.  Process capability is based on statistical techniques that are used to predict the complete output of a process based on a relatively small sample.  There are different ways to measure process capability including the capability ratio, capability index and the Cpk.  The Cpk is the most commonly used measure of process capability because it not only determines if the process is capable is meeting the spec, but it also predicts how well the process is centered on the nominal of the specification.
