Question: 1 / 400

Why are process capability indices important?

To determine sales performance compared to competitors

To assess how well a process meets specified limits

Process capability indices are important because they provide a quantifiable measure of how well a process can consistently produce output that meets specified limits or specifications. These indices, such as Cp, Cpk, Pp, and Ppk, help evaluate the variability of a process in relation to its tolerances. By assessing process capability, organizations can determine if their processes are capable of producing products that meet quality standards reliably and efficiently.

Understanding process capability assists quality engineers and managers in identifying whether a process is performing at an acceptable level or if improvements and interventions are necessary. This ensures that the outputs align with customer expectations and requirements, leading to higher quality products and reduced costs associated with defects, rework, or customer complaints.
