Critical Spares & Inventory Classification Model
A practical model for classifying critical spares, determining stocking strategies, defining authority, connecting items to operating consequence, and embedding controls into ERP-supported inventory governance.
Purpose
Enables asset-intensive organizations to classify inventory based on operational consequence, eliminate single-point operational vulnerabilities, and optimize working capital with audit-grade governance.
Who it is for
Maintenance Managers, Plant Directors, Supply Chain Leaders, Inventory Controllers, and Site General Managers.
What it examines
- Operational downtime consequence and asset criticality mapping
- Single-point failure exposures and lead-time volatility buffers
- Stocking strategy logic (Min/Max, ROP, Insurance Spares)
- Sign-off authority for critical item creation and parameter changes
- ERP inventory parameter locking and exception governance
