Next determine who your market really is. You may end up having two market demographics: one for the product and one for the opportunity. Develop a market plan for each demographic. Not everyone is an entrepreneur but they may still be interested in the product. This is why quality is key. The product has to be able to stand on its own without the opportunity. Not everyone is going to be interested in the product. Try to narrow down the demographics of those that would be interested so that you can communicate more receptively with your market.
Let us see what do we call a "marketing plan"? It is the result of the planning activity, a document that includes a review of the organization's place in the market, an analysis of the STEP factors as well as a SWOT analysis. A complete plan would also formulate some presumptions on why we think the past marketing strategy was successful or not. The next phase shall present the objectives we set, together with the strategies to achieve these objectives. In a logical sequence, we will further need to evaluate the results and formulate alternative plans of action. A plan would consist in details of responsibilities, costs, sales prognosis and budgeting issues.
