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.
So in order to bring success to your business, you need a strategic marketing plan. Strategic plans are classified according to their time frame to long, medium and short_ term plans. Usually long_term plans tend to be between 5┦ years at corporate level, medium_term plans 2λ years and short_term consists of a time period ranging from 6 months to 1 year.
