The purpose of the Marketing Plan is to identify and create competitive advantage. Marketing planning is the real form of the company to provide a strategic response to a changing global competition pattern consisting of: business size adjustments, changes in product and market scope, creation of new networking relationships with other organizations.
The plan should cover one year. For small companies, this is often the best way to think about marketing. Things change, people leave, markets evolve, customers come and go. Later on we suggest creating a section of your plan that addresses the medium-term future--two to four years down the road. But the bulk of your plan should focus on the coming year.
