Preparing a Business Plan: A business plan has to be in accordance with the organization in question, its situation and time. However, a business plan is not just a document to be produced and filed. Instead, business planning is a continuous process. The business plan has to be a living document, constantly in use of monitor, control and guide the progress of a business.
Business planning process : As discussed above, a successful entrepreneur lays down a step by step plan that he/she follows while starting a new business. This business plans acts as a guiding tool to the entrepreneur and is dynamic in nature - and needs continuous review and updating so that the plan remains viable even in the changing business situations.
So it is crucial that every time you mention financials in your business plan, to really give them the correct context. When I have worked with clients in developing business plans, there has been a budget or amount set aside for example to be spent on marketing, which has been decided a bit arbitrarily. I mean with no real research, no understanding of what that amount needs to be spent on, and what that budget will truly achieve.
If you are someone who shies away from planning, or you don't like writing or preparing documents, nevertheless you are going to have to force yourself on this occasion. I say that because it is such a key document for the future success of your business, such a tool throughout its development to return and refer to.
