Getting to plan B, by John Mullins and Randy Komisar, is an important book. In short, the thesis of the book is that successful startups very often had to change their initial business plan. To quote Mullins and Komisar: "If the founders of Google, Paypal or Starbucks had stuck to their original business plans, we'd likely never had heard of them." The startup process, largely driven by poorly conceived business plans based on untested assumptions, is seriously flawed. And the authors to give a few interesting examples of business plans changes that were successful. If only for this, the book is important because, despite many criticisms, business planning remains the cornerstone of entrepreneurship courses at business school, and well honed business plans are a must-have to pitch venture capital. The fact that no business plan survives the first encounter with reality seems to bother no one in industry. Importantly, the flaw does not lie in some limitations of the planners. In other words, it is not because of poor planners that business plans are useless, or even harmful. It is the very process of planning that is problematic. Behind the notion of planning lie the idea that to control the future, we need to predict it. However, recent research on entrepreneurship by Sarasvathy (see the concept of effectuation) showed that in uncertain environments, it is simply not possible to predict the future. Hence prediction is really a gamble.
