Control Chart

Public Health & QI ToolboxA control chart will help to monitor, control, and improve process performance over time by studying variation and its source. It helps to distinguish special from common causes of variation as a guide to local or management action. A process can be improved to perform consistently and predictably for higher quality, lower cost, and higher effective capacity. There are many types of control charts.

Once a process is selected to be charted, the sampling method and plan are determined. Data is then collected, statistics and control limits are calculated, and the chart is constructed.
