Technique Overview

Zero-based Budgeting Definition

Zero-based budgeting (ZBB) is a budgeting method where every expense must be justified based on its expected outcomes, without relying on previous budgets or achievements (McKinsey & Company, 2019). Each department starts from a "zero base" annually, requiring detailed justification for all expenditures. Top management approves budgets only when convinced that the proposed activities provide clear value for money (PwC, 2020). This approach ensures spending aligns with current priorities and optimises resource allocation across the organisation.
