Statistical process control charts display upper and lower limits for process variables or attributes, and signal when a process is no longer in control. They are used to monitor and control a process to ensure that it is producing products within specification limits. They do not display measurements of every item being produced or purchased, indicate the average outgoing quality of each lot, or display the true quality of material leaving the process.
