Strategy _ similar to business strategy, marketing plan will capture strategies required to support your business strategy. For example if your business goal is to achieve 20% increase in sales, your marketing strategy would be to 1) introduce new product, 2) increase price for premium offerings, 3) recruit more distributors and offer commission scheme and so on. Strategy is king. When you can see your business in totality, I can assure you that you will find it easier to manoeuvre. Marketing plan is the place to address all these issues.
You will need to develop or define important information about your company. In your business plan, you should have developed a Mission Statement, a Vision Statement, and a Culture Statement. If you did not develop these three items, you must create them immediately before continuing onward. It is vitally important that everyone knows about and buys in to these three company statements with all employee staff so that every person inside the business will communicate these items correctly to all external people outside of the business. You want their belief and confidence as high as the owners or top executives.
