People make business plans for all sorts of reasons — to attract funding, evaluate future growth, build partnerships, or guide development. Unfortunately, the vast majority of these plans are usually out of date by the time the printer ink dries. Business moves fast: the product’s features morph, new competitors emerge, or the economic climate shifts. When these changes occur, many people just throw their business plans out the window. For a plan to be truly valuable it needs to evolve with your company and stay relevant in the face of uncertainty.
