Which term can be used to measure the capability of a process?

The term that can be used to measure the capability of a process is Defects per Million Opportunities (DPMO). DPMO is a key metric in Six Sigma that quantifies the number of defects in a process relative to the number of opportunities for defects to occur, scaled to a million. This measurement provides a clear indication of process performance and capability, allowing organizations to understand how well a process meets specifications and customer requirements.

By calculating DPMO, organizations can benchmark their processes, make comparisons to industry standards, and identify improvement opportunities. A lower DPMO indicates a more capable process with fewer defects, making it a vital measure in quality improvement initiatives.

In contrast, Process Quality is more of a qualitative assessment that doesn’t quantify defects in a precise way, Just in Time (JIT) refers to inventory systems that optimize production efficiency rather than measuring capability, and Design of Experiments (DOE) is a statistical method used for designing experiments and analyzing data but does not itself measure process capability. Hence, DPMO stands out as the most relevant metric for assessing process capability in the realm of Six Sigma.
