Cumulative Flow Diagram (CFD)

A cumulative flow chart is a tool used in queuing theory. This is an area chart that represents the amount of work in a given state, showing arrivals, queue time, queue quantity, and the throughput.

The horizontal x-axis in a CFD indicates time, and the vertical y-axis indicates tickets. Each colored area of the chart equates to a workflow status.

The CFD can be useful for identifying bottlenecks. If your chart contains an area that is widening vertically over time, the column that equates to the widening area will generally be a bottleneck.
