What best describes 'process capability' in the context of quality assurance?

'Process capability' refers specifically to the inherent ability of a manufacturing process to consistently produce output that adheres to predetermined specifications and standards. This concept is crucial in quality assurance because it directly influences the reliability and quality of the products being manufactured.

When a process is capable, it means that the variations in its output are within acceptable limits, ensuring that customer requirements are met. This involves statistically measuring how well the process performs in relation to its limits and being able to predict future performance reliably.

In contrast, the other options either do not pertain to the core idea of process capability or address different aspects of manufacturing quality. For example, implementing new procedures, workforce training levels, or expected production costs may influence operational effectiveness or efficiency but are not direct measures of a process's ability to meet quality specifications.
