A cumulative flow diagram provides information on the flow of work in a process over time. It visually represents the movement of work items through different stages of the process, with each stage represented by a colored area. The height of each area represents the number of items in that stage at a specific time, while the horizontal axis represents time and the vertical axis represents the number of items in the process.

By analyzing the Cumulative Flow Diagram, you can identify bottlenecks, delays, and other issues that are slowing down the process, and track the effectiveness of process improvements over time.
