Quizplus · Accepted Answer

A process is said to be out of control when special causes are present, which means there are unexpected variations in the process that can cause defects or errors. Common causes, on the other hand, are expected variations that do not warrant any action. The capability of the process and the computation of control limits are not necessarily indicators of whether the process is in control or not.
