I am working in a Kanban process with a team the tries to estimate Cycle time, Lead time as well as completion time based on applying FIFO wherever possible on our queues.
Using the Cumulative Flow Diagrams is very helpful in this process. However most systems I have used do not account for time estimates in this graph. The latter vary significantly in my team and also differ between iterations.
The systems I have used so far, only count the tickets in the CFDs. Hence I largely discard them and measure velocity weekly, dividing completed story point estimates by the available resource in that week.
I am looking for a CFD and associated calculation of common metrics based on estimates. Are there any Kanban systems that can do this?
