5 Easy Facts About control limits Described

In this article, We are going to discover the traits of control limits and specification limits, highlighting their similarities and discrepancies.

Control limits are determined by the inherent variability of a method and are typically established at 3 regular deviations from the process indicate. They account for frequent induce variation and allow for normal approach fluctuations.
