Cumulative Flow Diagram (CFD) 

The 'Mother' of system-level metrics

The CFD indicates behaviour of the system over time. It encompasses a number of key indicators of how well the overall system is functioning.  

Clearly shows trends in the rate of demand and of the completion of work.

Visible bottlenecks and delays guide the team to making system-level improvements.  This is a useful way to get team and stakeholders to raise their heads up from the day-to-day work they are doing and be aware of higher level challenges.

 

 

A 'typical' CFD

This particular chart shows the work for the development of SenseAdapt, since we started development in May. We work in a Kanban-like way, deploying frequently to our internal demo-site and every week or two to customer sites. 

For more on the information you can get from a CFD I suggest Pawel Brodzinski's post  On how to read a CFD  

 

Actionable detail

As with all the SenseAdapt charts - users can click on the chart (1) see which user stories are/were in that state historically (3) - and click on the link (2) to open the story TFS 

 

Focus on a specific state over time

Unlike with most CFDs, you can easily filter the chart to look at the amount of work in a specific state over time e.g. Candidate stories (1) and see the trends over time (2)
