A control chart is a graphical tool used in statistical process control to monitor and track the variation in a process over time. It consists of a central line that represents the average or target value of the process, as well as upper and lower control limits. The control limits on a control chart are typically set at a certain number of standard deviations away from the process mean. These limits define the range within which the process is considered to be under control and performing acceptably. Control limits in a control chart represent the acceptable range of performance, defining the boundaries within which the process is considered to be under control and performing acceptably.
