Process capability is a statistical measure of the inherent process variability of a given characteristic. It assesses how well a process can consistently produce outputs within specifications. In a process capability study, we analyze the range of variation in the process to determine its ability to meet customer requirements or engineering tolerances. By understanding this variation, we can identify whether the process is capable of producing products that meet quality standards and expectations. The study does not specifically address the potential for errors, capacity, or the cause of special effects in the process12.
