Service-level agreements (SLAs) are the foundation of reliable vendor relationships. But in the post-pandemic, post-supply-shock world, yesterday’s SLA standards may no longer be realistic—or enforceable. Glass and ceramic buyers must now craft flexible, data-driven SLAs that reflect real-world conditions while still enforcing accountability.
Why Traditional SLAs Are Breaking
Fixed OTIF targets ignore capacity constraints and seasonal demand
Non-adjusted lead time expectations punish vendors unfairly during global shocks
Static penalties don’t encourage collaboration or transparency
Best Practices for Modern SLAs
1. Use Rolling Average Performance Metrics
Instead of fixed-point performance, calculate OTIF and lead time over 3–6 months to account for temporary disruption.
2. Create Tiers of SLA Targets
Differentiate between mission-critical SKUs and commodity items. Critical items may have higher penalties and tighter windows.
3. Add Flexibility for Verified Force Majeure Events
Build in clearly defined exceptions for port closures, border bans, or natural disasters—while still requiring timely updates.
4. Include Communication Response SLAs
Define how quickly vendors must alert you to disruptions (e.g., within 24 hours of event recognition).
5. Tie SLA Outcomes to Preferred Vendor Status
Reward high-performing vendors with more volume, faster payments, or first look at future opportunities.
Final Word: Today’s SLAs must reflect both operational accountability and adaptive resilience. That balance builds true vendor partnerships—not just contracts.
