Let's go over the budgeting process, including organizational benefits, as well as overall cost and benefits. We'll also cover the cash flow process and how management tracks all incoming and outgoing cash. Finally, we'll discuss capital budgeting and go over the different ways that you can calculate the value of your investments, like the unadjusted rate of return, net present value, and internal rate of return methods. Organizational budgeting is both a tool and a process by which management sets company goals and allocates resources to meet them. The main four budgeting types are incremental budgeting, activity-based budgeting, value proposition budgeting, and zero-based budgeting. Incremental budgeting is probably the most commonly used of the four types, and it uses the previous year's budget as the starting point for the new budget. Typically, managers will send the budget to the different departments with instructions on what their target budget amount should be. This budget typically gets recycled from year to year, with gradual changes to the amount for each department. Activity-based budgeting is a little different from the incremental approach. This is sometimes referred to as top-down budgeting, as upper management will set the organization's proposed revenue or output and then look at the inputs required to meet the proposed revenue. If management has realistic projections, then meeting the projected targets should be possible. Value proposition budgeting is rooted in lean theory, which stresses minimizing waste and maximizing value for an organization's stakeholders. In value proposition budgeting, all budget items are reviewed for necessity, cost, and value. Zero-based budgeting is another form of lean budgeting theory, in the way that the budgets start each new cycle with a zero balance. The departments must start at zero and build their budgets again in order to rethink all purchases and validate their necessity. Each budget item must be considered a necessity and will be used to generate revenue for the organization.
