1. The Inertia of Incremental Budgeting
Most companies use Incremental Budgeting, taking last year’s actual costs and adding a small percentage (e.g., +3% for inflation) to set the new targets. This approach is simple but carries a major flaw: it hides past operational waste and assumes every existing activity must continue indefinitely. 
 
2. The Core Philosophy of ZBB
Zero-Based Budgeting (ZBB) sweeps away historical baselines. Every single department starts the budget cycle with a clean slate of $0. Nothing is grandfathered in; managers must justify every single dollar of expense from scratch, proving that each activity adds direct value to corporate goals.
 
3. The Implementation Protocol
To execute ZBB, management follows a structured process:
  • Identify Decision Packages: Managers break their department’s operations down into distinct activity packages, detailing the goals, costs, and benefits of each task.
  • Cost-Benefit Evaluations: Upper management reviews each package independently to verify operational efficiency.
  • Rank and Allocate Funding: Senior executives rank all corporate packages based on strategic importance and fund them in order until the company’s budget resources are fully allocated.

While ZBB eliminates waste and slashes corporate expenses, it is highly demanding, requiring massive amounts of paperwork, staff hours, and detailed process analysis.
