Control Chart

A control chart is a visual tool used to monitor a process over time, helping to ensure it remains consistent and within desired limits. It plots data points, such as product measurements or process times, against time and includes upper and lower control lines that define acceptable variation. If the data stays within these lines, the process is considered stable. If points fall outside or show a pattern, it indicates potential issues needing attention. Control charts are essential in quality management to quickly identify and correct problems, maintaining high standards and efficiency.
