Why Department Budgets Matter
Without department budgets, AI costs are invisible until the monthly bill arrives. Marketing might consume 60% of the AI budget while engineering gets 10%. Department budgets create fairness, accountability, and predictability.
Budget Allocation Strategies
Equal allocation gives every department the same budget. Usage-based allocation uses historical patterns. Value-based allocation weights budgets by department AI ROI. Hybrid approaches combine these strategies with minimum baselines.
Hard Caps vs Soft Alerts
Hard caps (auto-stop) prevent any spending beyond the limit. Soft alerts notify department heads at thresholds (e.g., 75%, 90%). Best practice: use soft alerts for awareness and hard caps for absolute limits.
Monthly Review Process
Establish a monthly AI cost review: analyze spending patterns, identify optimization opportunities, reallocate unused budgets, adjust limits based on ROI data, and plan for growth.
