What is Process Capability Analysis?

Process Capability Analysis is a statistical method used to determine whether a process is capable of meeting specified limits. It assesses the inherent variability of a process and compares it to the acceptable variation specified by customer requirements or design tolerances. It is commonly used to ensure product quality and process consistency by determining if the process is 'in control' and capable of producing output within the desired specification limits. Key metrics include Cp, Cpk, Pp, and Ppk.
