i've been dreaming of a way that visualises the user flows in the software (rather than cards on a board), think spider map showing possible user flows then colour coded circles based on what stage they're in.
that way you can see what state an entire flow is in at a glance and being able to co-ordinate effort accordingly.
The first two (and I would say key) practices of Kanban (as a method) are: - visualize work(flow) - limit work in progress
So I wonder, how did these Kanban teams visualize work exactly?
Now, I don't say the whiteboard (virtual or physical) is the only way to do it, yet it's almost ubiquitous.
