In general terms, a capable process is one whose variability (σ) is small in relation to the distance between the centerline μ and the upper and lower specification limits.

Question

Quizplus · Accepted Answer

A capable process is one that can consistently and reliably produce output that meets customer specifications. One way to determine if a process is capable is to calculate its process capability ratio, which compares the spread of the process data (measured by σ) to the difference between the process mean (μ) and the specification limits. If the process variability is small relative to the specification limits, then the process is considered capable, indicating that it can produce products or services that meet customer needs within the desired tolerance range. Therefore, the statement is true.
