Question

Quizplus · Accepted Answer

Common cause variation is the natural variation that is inherent in a system and is not caused by any special or assignable factors. It is a normal part of any process and does not indicate that the process is out of control. On the other hand, special cause variation is the result of specific factors that can be identified and eliminated, indicating that the process is out of control and requires corrective action.
