The "Back of a Napkin" Plan: It is the source of entrepreneurial legend and lore, the million_dollar idea that was hurriedly scribbled on a bar napkin. Yet, for most potential business owners this option for business planning remains a fantasy. However, like any myth there is a tiny grain of truth inside. A quickie business outline can work as a launch plan under the right circumstances.
The "One Pressing Issue" Plan: Business planning does not stop the day you open for business. Under the best of circumstances you should be revisiting your plan once or twice a year to see how things are going, and where perhaps you've veered away from your original goals. Remember, changing the direction of a business isn't always bad, but it should be intentional.
