Entrepreneurs respond to attractive opportunities by forming new firms. In this chapter, we consider the five-step process for establishing a new enterprise. One particularly noteworthy step in the process is the development of a story and a business plan, including a compelling business model. The story is a compelling synopsis of why this venture is needed at this moment in time and how it can achieve success. We then detail the task of writing a business plan, which is an effort to better prepare the venture for testing its assumptions and hypotheses. An example of a well-prepared business model is provided in appendix A.
