Even though the summary will be read first, it is easiest to write it last – providing an overview of the complete business plan. The aim is to draw the reader in, so what you include will depend on your audience. If you are seeking funding you need to really sell your business idea in the summary.
Internally focused business plans target intermediate goals required to reach the external goals. They may cover the development of a new product, a new service, a new IT system, a restructuring of finance, the refurbishing of a factory or a restructuring of the organization. An internal business plan is often developed in conjunction with a balanced scorecard or a list of critical success factors. This allows success of the plan to be measured using non-financial measures. Business plans that identify and target internal goals, but provide only general guidance on how they will be met are called strategic plans.
If you don’t have a specific immediate need to show a formal business plan to a banker or investor, then you are probably better off doing just a lean business plan, for your internal use only. To make the best impression on banks and investors, your business plan outline should be presented in the standard business plan format.
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.
