If $f$ is an actual-valued purpose described on a set $Esubset mathbb R$ (or $subset mathbb R^k$), the upper and lower limits of $f$ at $x_0$ are denoted by

Control limits assist determine when a method is dealing with common cause variation, that's the inherent variability of the process. When information factors drop throughout the control limits, it implies that the method is steady and predictable.
