Driver-Based Budget Builder
Tie your budget to a real business driver — not last year's number plus 5%.
What you walk away with: A driver-based budget with ±20% scenario sensitivity built in.
Why it matters: Move from 'last year plus 5%' to a budget grounded in real business activity — and defend every line if the numbers move.
