In essence, here is a great way to think of superior business planning. Imagine you are taking a road trip from California to New York. No planning ("flying by the seat of your pants") would involve you getting in the car and driving "East" on every freeway you come across. Adequate planning would involve mapping out your course, planning where to stay overnight, where to eat, sights to see, and so forth.
If your answer is no, you may have been able to easily accomplish this goal by planning for such expenses in advance through a business plan. Even if having cash at the ready is not a viable alternative for you, you may have planned to have a line of credit available for such opportunities, knowing that in your field these opportunities do arise from time to time.
HELP...I Need Cash! (AKA Creating a Business Plan to Acquire Funding) ; Another reason to create a business plan is to acquire funding. In today's struggling economy, having access to cash as a small business is vital. In developing plans for this reason, a much more specific approach is taken. Here, the plan is created with a specific reader in mind: the lender. Whether seeking funds from a bank, an angel investor, or so forth, knowing your audience is vital.
Set out a basic management structure outlining who has responsibility for various aspects of the business. This will be easy in the beginning but eventually you may have marketing staff, administration staff, kitchen staff and servers. Make it clear how you plan on delegating tasks, leadership and responsibility for decision making down to your employees.
