Kanban metrics
A Cumulative Flow Diagram (CFD) is an area chart that shows the various statuses of work items for a particular time interval. 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.
The Control Chart can show the cycle time (or lead time) for your product, version or sprint. It takes the time spent by each issue in a particular status (or statuses), and maps it over a specified period of time. The average, rolling average and standard deviation (coming soon) for this data.
Here are some of the ways that you could use a Control Chart:
- Analyse your team's past performance in a retrospective
- Measure the effect of a process change on your team's productivity
- Provide external stakeholders with visibility of your team's performance
- For Kanban, use past performance to set targets for your team.
