In volatile environments, Supplier-Managed Inventory (SMI) programs offer a smart path to resilience. They allow vendors to hold stock based on shared forecasts, ensuring readiness while distributing risk. In glass and refractory categories—where product variety is high and lead times are long—SMI has become a preferred collaboration model.
Why SMI Is a Win-Win
Buyers reduce carrying cost and operational load
Suppliers get forecast visibility and production stability
Both share risk based on predefined thresholds
Core Elements of an Effective SMI Program
Forecast Sharing
Rolling 13–26 week forecasts shared electronically, updated regularly.
Stock Level Agreements
Minimum and maximum thresholds per SKU or product group.
Replenishment Triggers
Automated alerts based on drawdowns or usage thresholds.
Ownership Transfer Rules
Specify when inventory ownership moves—at shipment, invoice, or usage.
Penalties and Incentives
Missed stock levels may incur penalties; consistent availability can earn bonus volume or early payment.
Implementation Best Practices
Use integrated portals (SAP Ariba, NetSuite, Oracle) for visibility
Include shared KPIs: inventory turns, stockouts, forecast accuracy
Review every quarter and re-tier SKUs annually
Final Word: SMI isn’t just about stock—it’s about building shared accountability and agility between buyer and supplier.
