Definition

A control chart, also known as a Shewhart chart or process-behavior chart, is a graphical tool used to monitor and control process performance over time. Control charts display process data in a time-ordered sequence with upper and lower control limits based on statistical analysis of historical data. Control charts help identify trends, shifts, or anomalies in process variability and distinguish between common cause variation and special cause variation.
