Peter Rip writes: “In preparing for this entry, I started to ask myself how do I think about a business model? And how do I test if business models are complete, coherent, and compelling? When I worked at Bain in the early 1980s the firm then specialized in strategy and business definition, equally amorphous concepts. (Amorphous is good when you bill by the hour). We used to refer to three tests to define whether two companies were in the same business similarities of cost structures, competitors, and customers.”
