ABSTRACT
One of the best ways I’ve found to teach people about the components of a philosophy, lean in particular, is to compare the basic elements of that philosophy to something familiar to everyone, like the structural elements of a house-a foundation, the floor, two pillars, and the roof (see Figure 1.1). Unlike a real house, it seems to work better if we describe this one by building it from the top down instead of from the bottom up.
