Process capability compares the output of an in-control process to the specification limits by using capability indices. ... Process Capability Indices ... A process capability index uses both the process variability and the process specifications to determine whether the process is "capable"

Process capability analysis entails comparing the performance of a process against its specifications. We say that a process is capable if virtually all of the possible variable values fall within the specification limits.

Products must be designed within the process capabilities of intended manufacturing processes. Process capability indices provide a measure of the process relative to specification limits or tolerances and the parameter value relative to the process mean. ... Process capability can be expressed with an index.
