A Cumulative Flow Diagram (CFD) is an area chart that shows work-in-progress for a product, version or sprint. The horizontal x-axis in a CFD indicates time, and the vertical y-axis indicates cards (issues). Each coloured area of the chart equates to a workflow status (i.e. a column on your board).
A 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.
To view the cumulative flow chart:
- Access the Rapid Board using the top navigation bar, then select your Rapid View from the 'Rapid View dropdown' (see Using the Rapid Board).
- Click the Report tab, then select Cumulative Flow Diagram from the drop-down at left. The cumulative flow diagram for the version will be displayed (see screenshot below).
- The cumulative flow diagram is based upon your Column Mapping.
- To re-draw the chart excluding a column(s) or swimlane(s), or to apply a quick filter, click Refine.
- To select a different timeframe (past week/past month/past 3 months/past 6 months/all time/custom), click the date range at the top of the chart.
- To select a different date range, drag your cursor across the 'Overview' at the bottom of the chart.
