Process capability
The process capability is a measurable property of a process to the specification, expressed as a process capability index (e.g., C pk or C pm ) or as a process performance index (e.g., P pk or P pm ). The output of this measurement is often illustrated by a histogram and calculations that predict how many parts will be produced out of specification (OOS). Two parts of process capability are: # Measure the variability of the output of a process, and # Compare that variability with a proposed specification or product tolerance
