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.
Chart to success: We all know that plans are imperfect things. How can you possibly know what's going to happen 12 months or five years from now? Isn't putting together a marketing plan an exercise in futility . . . a waste of time better spent meeting with customers or fine-tuning production? Yes, possibly but only in the narrowest sense. If you don't plan, you're doomed, and an inaccurate plan is far better than no plan at all. To stay with our sea captain analogy, it's better to be 5 or even 10 degrees off your destination port than to have no destination in mind at all. The point of sailing, after all, is to get somewhere, and without a marketing plan, you'll wander the seas aimlessly, sometimes finding dry land but more often than not floundering in a vast ocean. Sea captains without a chart are rarely remembered for discovering anything but the ocean floor.
