This. The real value in creating a "business plan" is in the focusing of your business. It isn't necessarily a good idea to go into business completely blind with no knowledge of who your potential customers and competitors are and what your revenue model is. Writing a business plan forces you to think through these key components. The definition of a "business plan" should be flexible. I prefer to use three pages or less, single spaced. That's enough room to cover all the topics while keeping it brief. There will be time to make revenue models and projections once you actually have some sales on which to base your calculations.
