This post is a brief follow-on to a great post by Tristan Kromer in which he describes what he calls the Lean Waterfall. In the lean waterfall, large organizations still maintain their silos (e.g. design, engineering and marketing). Within each silo, they practice agile and lean. However, between the silos there are still handoffs and large specification documents. As such, in the end what you have is an organization that looks like the graph below; with each departmental silo claiming to be lean, but at the super-ordinate level the organization is still functioning as a waterfall.
