What is ZBB?
Zero-based budgeting (ZBB) is a budgeting process that allocates funding based on program efficiency and necessity rather than budget history.1As opposed to traditional budgeting, no item is automatically included in the next budget.2In ZBB, budgeters review every program and expenditure at the beginning of each budget cycle and must justify each line item in order to receive funding. Budgeters can apply ZBB to any type of cost: capital expenditures; operating expenses; sales, general, and administrative costs; marketing costs; variable distribution; or cost of goods sold.3When successful, ZBB produces radical savings and liberates organizations from entrenched departments and methodologies.4When unsuccessful, the costs to an organization can be considerable.

Global macroeconomic factors are having a major impact on cost management efforts at large US companies. While the domestic economy has gained significant strength, other parts of the world are still struggling. This has created a cost/growth paradox we call “thriving in uncertainty,” where companies are simultaneously pursuing the seemingly conflicting goals of aggressive cost improvement and aggressive growth. Deloitte’s fourth biennial survey of cost management and cost improvement trends explores how companies are managing costs in this challenging environment.
