Zero-Based Budgeting in Practice

Introduction

Traditional incremental budgeting starts from last year's figures and adds a percentage. Over time this locks in inefficient spending, hides activities that no longer create value and makes it hard to redirect resources towards strategic priorities.

This Zero-Based Budgeting in Practice training course shows participants how to build budgets from a zero base, where every cost must be justified by the value it delivers. Participants learn how to define decision units, analyse activities and cost drivers, build decision packages at different service levels and rank them against organisational objectives.

The course takes a realistic, practical view of zero-based budgeting. It explains where the full approach adds most value, where lighter variants are more appropriate, how to manage the workload and resistance that often accompany it, and how to turn one-off savings into a lasting culture of cost ownership.

Course Objectives

By the end of this training course, participants will be able to:

• Explain the principles of zero-based budgeting and how it differs from incremental and activity-based budgeting
• Define decision units, cost categories and cost owners for a zero-based exercise
• Analyse activities, cost drivers and service levels to challenge existing spending
• Prepare decision packages with clear options, costs, benefits and risks
• Rank and select decision packages using objective prioritisation criteria
• Integrate zero-based budgeting with strategic planning, forecasting and performance reporting
• Manage stakeholder engagement, workload and resistance during a zero-based programme
• Sustain savings through governance, cost ownership and periodic zero-based reviews

Target Audience

This training course is suitable for a wide range of professionals, including:

• Finance managers, budget controllers and FP&A professionals
• Chief financial officers and finance directors
• Cost centre and departmental budget holders
• Strategy and transformation managers
• Public sector budget and planning officers
• Internal auditors reviewing budgeting processes
• Business partners supporting operational managers

Training Methodology

Participants learn through short briefings, worked examples and a running case study in which they build a zero-based budget for a support function. Group exercises cover activity analysis, decision package design and prioritisation workshops, while discussions draw on participants' own budgeting challenges to identify practical improvements they can apply immediately.

Target Competencies

• Zero-based budget design
• Cost driver and activity analysis
• Decision package preparation
