I teach that you should seek to learn from competitors; obviously never copy another business's idea or what they are doing, but you can absolutely learn from their mistakes or see what they are doing and discover ways to improve it. All of that analysis belongs in your business plan: make sure you have your competitors under the microscope and make sure that is a solid chunk of your plan. That is some of the best research and information you will gather about what will make your business successful in future.
Once you chose which one or more of the 7 you want to use and calculate exactly how much impact they have on meeting your plan, you would now have a definite approach on how to make your plan work. It seems simple. At that's what it's all about. It's about how to make your plan work the easiest and smartest way you can eliminating all the guesswork or trial and error methods. Want to increase your profit? This is a good way to do it. So, you see, once you decide which of the 7 ways you're going to do, then the only thing left for you to do is figure out how to make the one or ones you have chosen work.
