The business model is the description of the set of fundamentals that allows a company to make money. In its most basic form, it needs to make explicit Who the customer is and what she values (e.g. for Ferrari cars: 0.5% income percentile that values fast cars) How do we make money (Ferrari: by selling cars with specialized engines at four times production cost) Economic logic of how to deliver value to customers at appropriate price (Ferrari: focus on brand building, do not allow customers the resale of used cars, but require them to return them to dealership) Ferrari is actually quite a sophisticated example due to their specific resale policy, with which they control the market. For most products this is much easier
