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.
No doubt there would be a lot work to do to do a plan like this. You would need to figure out how to put it all together, do all the calculations, do a lot of what if's, etc.. And I'm sure one of the biggest things would be, would you actually take the time to do something like this or even have the time to do it? You could pay someone to do it but that would probably cost you a lot. Plus if you did that, most likely it would require a lot of back and forth work to get it just like you wanted it which would be even more expensive. But even then, would you spend the money to do it? There is a better way. If you would like to develop a nice plan like this for yourself and give yourself a good shot at making your life better, then find a planning software that does it all for you.
