They are making the daily decisions that affect your business. In order to facilitate the company-wide absorption of your vision, it's important that your plan be wide and shallow. Concentrate on explaining the mission and goals of each business area in a concise manner. Let your employees worry about the details, but make sure that they are clear on their destination. Building a plan that you can transfer to your staff is probably the most difficult thing to do.
Most plans end up in a file cabinet once some funding comes in.
All that research and thinking is then wastefully rehashed. Do what you can to transfer control of the plan to your employees. Moving the plan to some kind of groupware format would likely help. Remember, your company is now a team, and every team needs a game plan. You've worked long and hard perfecting your business plan, don't forget to use it.
