Captured thinking: You don't allow your financial people to keep their numbers in their heads. Financial reports are the lifeblood of the numbers side of any business, no matter what size. It should be no different with marketing. Your written document lays out your game plan. If people leave, if new people arrive, if memories falter, if events bring pressure to alter the givens, the information in the written marketing plan stays intact to remind you of what you'd agreed on.
Company operational instructions: Your child's first bike and your new VCR came with a set of instructions, and your company is far more complicated to put together and run than either of them. Your marketing plan is a step-by-step guide for your company's success. It's more important than a vision statement. To put together a genuine marketing plan, you have to assess your company from top to bottom and make sure all the pieces are working together in the best way. What do you want to do with this enterprise you call the company in the coming year? Consider it a to-do list on a grand scale. It assigns specific tasks for the year.
