How can you improve your plan? Once you've answered these questions, you have a basic blueprint of how your business is going to look at the early stage. Remember, your first step is to prepare a basic business plan that serves as a foundation. From this foundation, you will want to further explore areas which need more analysis and testing, while some aspects of your business venture merely require you to get started and measure how things are going.
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.
