It visualizes the stability, speed, and bottlenecks in the team's work. ### Why it is needed - helps see where tasks "get stuck"; - shows the balance between the input and output of tasks; - allows measuring **cycle time**, **throughput**, and **forecasting when work will finish**. ### What it looks like On the **X** axis - time, on the **Y** axis - the number of tasks. Each status (To Do, In Progress, Done) is shown as a separate colored band, and its thickness shows the accumulation of tasks. - If the *In Progress* band grows, tasks are piling up and the team is overloaded. - If the bands are parallel, the process is stable. - If "Done" grows linearly, the team is releasing tasks at a steady pace. ### How to interpret it - **Band width** = duration of the stage → lets you calculate the *cycle time*. - **Slope of the "Done" line** = the speed of completing tasks (throughput). - **Widening band** = delays or uneven workload. ### Conclusion **A Cumulative Flow Diagram** is a tool for visual control of task flow. It shows how stable the process is, where the bottlenecks are, and how fast the team turns tasks into a finished result.For the reviewerNote to the moderator (optional)Visible only to the moderator.
