Identify the Target Customers: Unlike the broader analysis of the market; here you aim on the targeted customers. You look for the scopes where you can promote or market your product to get the higher returns and acceptance. Here from targeted customers to clients, you also find out the needs and demands of the audience. Once you know, who all are your customers and what exactly they are looking for then you can jump to next step.
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.
