What is Capability Analysis?

Capability analysis is a statistical method used to determine whether a process is capable of meeting a set of specifications or customer requirements. It involves comparing the output of a process to its specification limits and calculating capability indices (e.g., Cp, Cpk, Pp, Ppk) to quantify the process's ability to consistently produce output within the desired range. Commonly used to assess and improve manufacturing processes, service delivery, and other processes where consistent performance is critical.
