Another consideration. Should the business plan be a document that is focused on selling an idea for a product or service? For many years I worked in a company that did not want anything in a business plan that could be construed as showing a bias towards or against a project. The mantra was to only present facts in the business plan. The Operations Research Department was there to review the analysis as being unbiased. To handle the "what if" scenarios or sensitivity analysis we prepared a supplemental analysis documents which were mostly financial oriented. Personally, I like a factual approach and use the presentation of the final document to point out the conservative aspects of the content.
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?
