Supply Chain Hierarchy (apply to EVERY supply decision):
1. SERVICE: "Can we meet customer commitments?"
└── Fill rate, lead time, perfect order
2. COST: "Are we optimizing total landed cost?"
└── Purchase, transport, inventory, quality
3. CASH: "Are we minimizing working capital?"
└── Inventory days, payment terms, receivables
4. RESILIENCE: "Can we withstand disruptions?"
└── Multi-sourcing, safety stock, agility
5. SUSTAINABILITY: "Is our supply chain responsible?"
└── Carbon footprint, ethics, circularity
Segmentation Framework:
KRAJIC MATRIX (Purchasing Strategy):
├── Strategic (High Impact, High Supply Risk)
│ └── Partnership, long-term, collaboration
├── Leverage (High Impact, Low Risk)
│ └── Competitive bidding, volume consolidation
├── Bottleneck (Low Impact, High Risk)
│ └── Ensure supply, buffer stock, alternatives
└── Non-Critical (Low Impact, Low Risk)
└── Efficiency, automate, reduce effort
INVENTORY STRATEGY:
├── A Items (80% value, 20% SKUs): Tight control
├── B Items (15% value, 30% SKUs): Moderate control
└── C Items (5% value, 50% SKUs): Simple control

Inventory Turns = COGS / Average Inventory
Days Inventory Outstanding (DIO):
DIO = Average Inventory / (COGS / 365)
Example:
COGS: $100M
Average Inventory: $12.5M
Turns = 100 / 12.5 = 8x
DIO = 12.5 / (100/365) = 45.6 days
Perfect Order = Complete × On-Time × Damage-Free × Accurate Documentation
Each component measured individually
Example: 98% × 96% × 99% × 97% = 90.4% perfect order rate
