This Petri net models the kind of 2-tier MMF->user story product development process that Karl Scotland described here or that I described here.

This model is a simplification of a real software development workflow. It lacks some of the buffering and backflows that you would see in the real thing. If you want to see it in action, I have a PNML file that simluates the left-hand side of this diagram. I used the PIPE2 editor, which does not support color or hierarchy, so that model is limited to a single feature kanban with no detailed story workflow. It’s still fun to watch, and gives you some sense of how planning can be implemented in a pull system using minimum marketable features, rolling wave planning, and staged delivery.
