A business plan is not a document you create once and store in your bottom drawer. It is a living guide that you should develop as your business grows and changes. Successful businesses review and update their business plan when circumstances change.
Set yourself a reminder to review your business plan regularly. If you have a team in your business, holding brainstorming sessions is a good way to benefit from their knowledge - it ensures you are all on the same page and that you get their support.
The planning process helps you learn about the different forces and factors that may affect your success. If you are already in business, it helps you to step back and look at what is working and what you can improve on. Instead of worrying about the future, a business plan helps to give you a sense of control over your business and your livelihood.
Business plans are decision-making tools. The content and format of the business plan is determined by the goals and audience. For example, a business plan for a non-profit might discuss the fit between the business plan and the organization’s mission. Banks are quite concerned about defaults, so a business plan for a bank loan will build a convincing case for the organization’s ability to repay the loan. Venture capitalists are primarily concerned about initial investment, feasibility, and exit valuation. A business plan for a project requiring equity financing will need to explain why current resources, upcoming growth opportunities, and sustainable competitive advantage will lead to a high exit valuation.
