Cumulative Flow Diagram

The Cumulative Flow Diagram (CFD) is an analytical tool used in agile project management to visualize workflow stability and predictability. It displays the total number of work items in each state of the workflow over time, typically using different colored bands for each state (e.g., to-do, in progress, done). The horizontal axis represents time, while the vertical axis shows the cumulative count of work items. By analyzing the width of the bands, teams can assess work in progress (WIP) levels, identify bottlenecks, and monitor throughput. A stable CFD indicates a balanced workflow, where work items smoothly transition through stages without significant delays. If the 'in progress' band widens over time, it suggests accumulating WIP, which can lead to longer cycle times and reduced efficiency. The CFD helps teams make data-driven decisions to optimize their processes by limiting WIP, reallocating resources, or addressing systemic issues causing delays. For a Disciplined Agile Scrum Master, the CFD is invaluable for facilitating continuous improvement. It provides insights into how work flows through the system, enabling the Scrum Master to coach the team in implementing practices that enhance flow, such as Kanban principles. By leveraging the CFD, teams can achieve higher predictability, deliver value more consistently, and respond effectively to changing priorities.
