Control limits are statistical values that show the acceptable variation in the means when a process is in control. They are calculated based on the mean and standard deviation of a process and indicate the range within which the process is expected to perform consistently. If a data point falls outside the control limits, it suggests that the process has changed and requires investigation to identify the sources of variation. Therefore, control limits help in monitoring the stability of a process and identifying opportunities for improvement.
