CPL 1 implies that the process mean is more than 3 standard deviation away from the lower specification limit.

Question

CPL >1 implies that the process mean is more than 3 standard deviation away from the lower specification limit.

Quizplus · Accepted Answer

CPL stands for Capability index for the upper specification limit. It is calculated as (USL - mean)/ (3 x standard deviation). A CPL value greater than 1 indicates that the process mean is more than 3 standard deviations away from the lower specification limit (LSL). Therefore, the statement is true. This statement is true. CPL (Capability index for the upper specification limit) greater than 1 indicates that the process mean is more than 3 standard deviations away from the lower specification limit, which means it is capable of producing output beyond the upper specification limit with minimum variation.
