Assess your competition. Understanding your competition is an essential component to understanding any business environment. Whatever the business you are looking to establish, you will always have competition in varying degrees. Perhaps you want to open a restaurant in an area that is already saturated with eateries; you then need to think about what is the unique selling point of your restaurant. Or maybe you have found a niche in the market, why is that? In order to make your business a success you should look to your competitors to see how they are managing their business or areas where they could improve. You also need to assess whether you can compete effectively with the existing businesses and how you plan to do so.
It should include a market research that identifies your competitors, their share of the market and the range of the products they produce. By learning how they conduct their operations, you may learn tricks of the trade in the business you want to enter and you also get to have a basis on what you can do to excel.
Finally, a business plan should be error - free. This is important because your business plan defines who you are as a business person. If it turned out sloppy, then that does not speak too highly of you.
It also needs to be written in formal format and style. You have to remember that a business plan is something that you may have to present to your business partners, financial firms and banks. So if you can, refrain from using slang in any part of your plan.
