What are the similarities between planning programming budgeting and zero based budgeting?

Both planning programming budgeting (PPB) and zero-based budgeting (ZBB) emphasize a structured approach to resource allocation and prioritization. They focus on aligning budget decisions with organizational goals and objectives, ensuring that resources are allocated based on necessity rather than historical spending. Additionally, both methods require thorough analysis and justification of expenses for each budget cycle, promoting efficiency and accountability in financial planning. Ultimately, they aim to enhance decision-making and improve the effectiveness of resource utilization.
