What is process capability

Question

Accepted Answer

Process capability is the ability of a process to produce output within the specified limits of customer requirements.

Process capability is a statistical measure that compares the variability of a process output to the variability of customer requirements.
It helps to determine if a process is capable of producing products that meet customer specifications.
Process capability is usually measured using indices such as Cp, Cpk, Pp, and Ppk.
A process with a high capability index indicates that it is producing products that are within the customer's requirements.
Process capability analysis is important in quality control and improvement.
For example, a manufacturing process that produces car parts must have a high process capability to ensure that the parts meet the required specifications.
Process capability can be improved by identifying and eliminating the sources of variation in the process.
