Go Deeper: What is a Control Chart?
Control Charts Evaluate Process Performance Over Time
A control chart is a smart line graph. It performs calculations on your data and displays:
- the average or median as a center line.
- the amount of variation in data using control limit lines.
Control Charts Contain These Key Elements
As data moves through the zones created by these control limits, a control chart highlights data points or trends that should be investigated.
An Upper Control Limit (UCL) line calculated at 3 sigma above the Center Line.
A line chart of data measuring the process over time.
A Center Line calculated as the average or median of the data.
A Lower Control Limit (LCL) line calculated at 3 sigma below the Center Line.
A control chart is a line graph with built in intelligence that analyzes your data for you.
