I’ve recently settled on a visual representation of Kanban Thinking which has been working well. The structure took shape when I realised that Flow, Value and Capability were system impacts. Those are the arrows coming out of the right hand side of the central System. The arrows going into the left hand side are the levers we have to influence the system behaviour; Study, Share, Limit, Sense and Learn. The primary lever is limiting. Studying and sharing provide the transparency and visibility to enable the limits. Sensing and learning give the feedback to evolve the limits.
Feel free to use this picture. I hope it proves useful.
