Thoroughly cover your business' market. Talk about your industry and use specific details to support your statements. Details like industry size, growth rate and customer group will help you showcase your business. Include as many details as possible. Do not fill this section with generalized information. Make sure it is industry and business specific.
Be sure to check out your local college library as well. Often, academic libraries will have more comprehensive business books than local libraries, and may offer a wider selection of in-depth materials regarding not only writing a business plan, but strategizing how to continue with your business development afterward. Keep in mind that many university libraries are open only to students, so call the resource desk before you make a special trip onto the campus.
