What does "process capability" measure?

• A. The efficiency of a workforce in quality management
• B. The ability of a process to produce output that meets specification limits
• C. The overall satisfaction of customers with a product
• D. The financial cost of poor quality

Answer: (B)

"Process capability" specifically measures the ability of a process to produce output that consistently meets specified limits or requirements. This concept is fundamental in quality management because it quantifies how well a process is performing and how capable it is of producing products or services that meet the desired quality standards.

In a successful quality management system, organizations strive to ensure that their processes are capable of producing outputs within defined specification limits. By assessing process capability, organizations can identify variations, determine performance, and implement improvements where necessary. This measurement is often expressed using statistical indicators like Cp and Cpk, which provide a numeric value representing the process's ability to produce quality output.

The other options touch on important aspects of quality management but do not specifically define process capability. Efficiency of workforce relates to how well employees or systems utilize resources, customer satisfaction addresses the end-user's experience with a product, and the financial cost of poor quality refers to the economic impact of defects or failures within the production process. However, none of these directly relates to the fundamental measurement of process capability.
