When I ask entrepreneurs and small business owners, it is not unusual for not having any marketing plan. I once read that Sir Richard Branson never had any marketing plan when he started the 1st Virgin business many years ago. In fact in one study of entrepreneurship (I couldn't recall the name of the study) was that as much as 50% of entrepreneurs and business owners don't have a business plan and marketing plan when they first started the business.
Situation Analysis _ This is the current state of your business. It is where the question of why you are in business is answered. What products do you offer? What problem are you trying to solve? Also, how is your business different than others? The situation analysis is a look at the inner_workings of your business to identify product and service offerings, differences, and the main reason why you exist. Business owners can build a firm foundation for their mission and vision statement with this information and are better able to communicate their value to customers.
