It helps see how stably the team is working and where delays appear. ### How the diagram is built - **X axis** - time (days, weeks, sprints). - **Y axis** - the total number of tasks. - Each process stage (*To Do, In Progress, Review, Done*) is shown as a **colored band**. The wider the band, the more tasks are at that stage. ### What the CFD shows 1. **Flow stability** If the bands grow evenly and in parallel, the process is balanced. If one of the bands widens, a bottleneck is forming there. 2. **WIP (Work In Progress)** The distance between "To Do" and "Done" shows how many tasks are in progress at the same time. 3. **Throughput** The slope of the top "Done" line reflects the speed of completing tasks. 4. **Cycle Time** The horizontal distance between the "start" and "finish" of tasks shows how long completion takes. ### Example interpretation - If "In Progress" grows faster than "Done", the team is not keeping up with finishing tasks. - If all the bands move evenly, the flow is stable. - If "steps" appear, the process has periods of idle time or sharp spikes in load. ### Conclusion **A Cumulative Flow Diagram** is a tool for analyzing the stability and efficiency of flow. It shows **where work is slowing down, how many tasks are in progress, and how predictable the process is**.For the reviewerNote to the moderator (optional)Visible only to the moderator.
