At its core, a business plan helps you prove to yourself and others whether or not your business idea is worth pursuing. It’s the best way to take a step back, look at your idea holistically, and solve for issues years down the road before you start getting into the weeds.
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.
Your business plan should present what a banker or venture capitalist expects to see, in the order they expect to see it in. Following a standard business plan outline will keep you on track, and save you from botching your best chance at getting your business funded.
Having an understanding with third parties when distributing a plan could be enough protection for some businesses, however others who have innovative business practices or products or services may wish to go further and sign a confidentiality agreement with each person to protect their innovations. It may also be a good idea to include some words in your plan asking the reader not to disclose the details of your plan.
