All three statements are assumptions of process control. The assumption that random variability cannot be eliminated unless the process is redesigned implies that process control aims to reduce variability rather than completely eliminate it. The assumption that common causes represent random variability acknowledges that some variability will always be present in a process, and the goal is to identify and control the sources of that variability. Finally, the assumption that production processes are not usually found in a state of control implies that process control requires ongoing monitoring and adjustment to maintain control.
