Since your mission statement is only a few pages long, your executive summary will allow you to further expand upon key points mentioned in the mission statement. Consider including your business history, biographies of key players, an overview of the business including locations, employees and available products and services. You can also discuss goals and future plans. Use this section to really draw in the readers.
In this section you should also include the results of any market research studied that your company has completed. Also briefly discuss your competitors and their strengths and weaknesses. You may want to cover how your services will appeal to customers more than your competitors.
