Building a business plan is a lot like planning a long cross-country flight as a pilot. You have data that you know for certain such as where you are going, the route to be flown and the basic performance of the aircraft. You are also faced with a set of data that is less certain – the forecast weather, potential equipment failures, your own fatigue level etc. A good pilot examines the uncertain data and builds a contingency plan before committing to the flight. The point is that this thought process takes place BEFORE you leave the ground.
