If the variation in the process is due to common causes alone, the process is said to be in statistical control. This means that the variation in the process is stable and predictable, and can be measured using statistical process control techniques. Out of control refers to a process where the variation is not stable and predictable, and there are special causes of variation present. In pre-control refers to a simpler method of controlling a process that has low capability. Out of capability refers to a process that cannot consistently meet the specification limits.
