1. Run Chart A run chart , is a line graph that displays observed data in a time sequence. Run charts cannot tell you if a process is stable. However, they can show you how the process is running. The run chart can be a valuable tool at the beginning of a project, as it reveals important information about a process before you have collected enough data. © Sun Technologies Inc. 1

2. Using run charts to detect "special causes" of variation: If you have 5 points or more in your data series, you can use run charts to detect special causes - something beyond the usual variability of the process -acting on the process. If you see 3 points or more consecutive points on one side of the center line that indicates that a special cause has influenced the process. Points on the center line don't count. © Sun Technologies Inc. 2
