What is the goal of a process capability analysis?

The goal of a process capability analysis is to determine how well a process can produce output within specified limits. This involves statistically assessing the performance of a process to see how much variation exists in the outputs and whether that variation possesses a consistency that meets the predefined specifications.

Essentially, process capability is about understanding the inherent ability of the process to generate products or services that meet quality standards consistently. By analyzing this capability, organizations can identify whether improvements are needed to bring processes into alignment with quality requirements or customer expectations.

This concept is crucial for ensuring that processes remain effective and are capable of delivering quality outputs that meet customer requirements. In contexts where production output must meet strict regulations or standards, a firm grip on process capability can significantly influence overall quality and operational success.
