A control chart is used to communicate performance data in a time sequence. It is designed to plot data points chronologically to identify trends, variations, and patterns over time, which is essential for process monitoring and improvement. Reference: "Introduction to Statistical Quality Control" by Douglas C. Montgomery, which explains the application and interpretation of control charts in quality control.
