Created using Hakan Forss’s guide to creating a CFD in excel (http://hakanforss.wordpress.com/2011/06/17/cumulative-flow-diagram-how-to-create-one-in-excel-2010/) , the Cumulative Flow Diagram is the chart of choice to see how a team is working together and to what extent the work is naturally flowing through the value chain.
The x-axis represents time.
The y-axis represents either number of tasks/stories or the number of story points.
Each line represents a flow state for the team with the top line being the starting point of the flow and the bottom line being the end point of the flow.
As work moves between into a flow state the line for that state increments upwards.
This graph is used to determine the amount of work in progress, the cycle time and bottlenecks in flow.
