One way to look at lean is that it's all about enabling the continuous flow of actions, information, materials, services and cash in such a way that these things generate goodness, however you may define that. The theory is that when things flow they take less time and resources. When this theory fails, lean says that a problem has been exposed and that by solving this problem we win in two ways: by enabling flow and by getting rid of that problem. Relentless focus on continuous flow can create a positive feedback loop.
