That is a great thing to make sure you have in your business plan, that your business will be built around those real customer wants. Do not make callous assumptions, or statements like "I know what people want", "People are going to love this", and so on. Have you done your research? Do you really know that the people you will be targeting want your product / service, and crucially do they want it AT THE PRICE that you will be offering it at? Whilst confidence in your plan is fantastic, you must make sure that it does not lead you down a blind alley along a path that is not desired by your target market. Don't assume what customers want, do your research and make sure that is clear from the start in your business plan.
A business plan is therefore an outline for taking an idea for a product or service and turning it into a commercially viable reality. It's a roadmap of the business you intend to start and without it you may end up getting lost on the way. It should therefore be remembered that having generated your business ideas and analyzed them to come up with the most viable idea, it's important to create a business plan for your online home business. Do you have one?
