Zero-based budgeting (ZBB) is a budgeting method that requires all expenses to be justified and approved in each new budget period, typically each year. It was developed by Peter Pyhrr in the 1970s. This budgeting method analyzes an organization's needs and costs by starting from a "zero base" (meaning no funding allocation) at the beginning of every period. The intended outcome is to access the efficient use of resources by determining if services can be provided at a lower cost. However, the saving comes at the expense of a complete restructuring every budget cycle. Although used at least partially in both government and the private sector, there is some doubt whether ZBB has ever been utilized to its fullest extent in any organization.
