What does Process Capability measure?

• A. The effectiveness of marketing strategies
• B. The variability of a process characteristic
• C. The efficiency of resource allocation
• D. The quality of customer service

Answer: (B)

Process capability specifically measures the variability of a process characteristic, focusing on how consistently a process can produce outputs that meet specifications. It is expressed using metrics such as Cp and Cpk, which quantify the extent to which a process operates within preset limits or tolerances. By analyzing process capability, organizations can determine whether their processes are stable and capable of producing products that conform to quality standards without excessive variation. This assessment is critical for continuous improvement initiatives, as it helps identify areas where processes may need adjustment to enhance quality and consistency. Understanding process capability is central to operations management because it directly impacts product quality, operational efficiency, and overall customer satisfaction.
