Top-level reflection: In the daily hurly-burly of competitive business, it's hard to turn your attention to the big picture, especially those parts that aren't directly related to the daily operations. You need to take time periodically to really think about your business--whether it's providing you and your employees with what you want, whether there aren't some innovative wrinkles you can add, whether you're getting all you can out of your products, your sales staff and your markets. Writing your marketing plan is the best time to do this high-level thinking. Some companies send their top marketing people away to a retreat. Others go to the home of a principal. Some do marketing plan development at a local motel, away from phones and fax machines, so they can devote themselves solely to thinking hard and drawing the most accurate sketches they can of the immediate future of the business.
Rallying point: Your marketing plan gives your troops something to rally behind. You want them to feel confident that the captain of the vessel has the charts in order, knows how to run the ship, and has a port of destination in mind. Companies often undervalue the impact of a "marketing plan" on their own people, who want to feel part of a team engaged in an exciting and complicated joint endeavor. If you want your employees to feel committed to your company, it's important to share with them your vision of where the company is headed in the years to come. People don't always understand financial projections, but they can get excited about a well-written and well-thought-out marketing plan. You should consider releasing your marketing plan--perhaps in an abridged version--companywide. Do it with some fanfare and generate some excitement for the adventures to come. Your workers will appreciate being involved.
