I’ve been working on ways of getting data out of Jira that is a actually helpful.
As you know, boards (and reports) in most tools are just views on the data that is there.
So you can combine different workflow-states in different boards to highlight interesting facts.
One of these visualisations is what I call a Cummulative FlowEfficiency Diagram (CFED).
In this Diagram I combine all the queueing states (waiting) and all the working states to see how the FlowEfficiency of the Kanban System changed over time.
