Question

Quizplus · Accepted Answer

The C_p index (also known as Cpk) is specifically designed to determine the capability of a process to meet its specifications. The Cpk value represents the minimum distance between the process mean and the specification limit, divided by the process variation. A value of 1 or greater indicates that the process is capable of meeting its specifications, while a value less than 1 indicates that the process is not capable. Therefore, D is the best choice for determining process capability. Pareto charts, cause-and-effect diagrams, and histograms can be useful tools for identifying potential causes of process variation, but they do not directly measure process capability.
