What is capability studies?

Capability studies are statistical analyses used to determine if a process is capable of consistently producing output that meets customer specifications or internal requirements. They typically involve collecting data on a process, calculating process capability indices (like Cp, Cpk, Pp, and Ppk), and comparing these indices to predetermined acceptance criteria to assess whether the process is capable, not capable, or needs improvement. They are commonly used in manufacturing, healthcare, and other industries to monitor and improve process performance, reduce defects, and ensure quality.
