Drawing on research undertaken in the history and philosophy of science, with particular reference to the extensive literature which discusses the use of models in biology and economics, we explore the question ‘Are Business Models useful?’ We point out that they act as various forms of model: to provide means to describe and classify businesses; to operate as sites for scientific investigation; and to act as recipes for creative managers. We argue that studying business models as models is rewarding in that it enables us to see how they embody multiple and mediating roles. We illustrate our ideas with reference to practices in the real world and to academic analyses, especially in this Long Range Planning Special Issue on Business Models.
