Business Planning is a decision making process intended to select a portfolio of investment decision unit that best achieve a set of strategic goals and objectives. Business Planning leverages technical models and economic assumptions provided by others to generate forecasts of portfolio cash flows, operational results and financial metrics. The recommended and approved portfolio, or scenario, is documented to become the business plan.  Neither the actual execution of the selected decision units, nor the stewardship of that execution, are within the scope of business planning.  Business Planning does, however, include lookback analysis, which is used, among other purposes,  to ensure that inputs to Business Planning are as realistic and objective as possible. Business Planning as a process includes the development of a long range plan and the budget.
