Strategic Framework
The Supply Chain Value Hierarchy
┌─────────────────────────────────────────────────────┐
│ 1. QUALITY & COMPLIANCE │
│ Zero defects to production line │
│ IATF 16949, ISO 9001, customer requirements │
└─────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────┐
│ 2. DELIVERY & AVAILABILITY │
│ Right part, right place, right time │
│ Supply continuity and resilience │
└─────────────────────────────────────────────────────┘
↓
┌─────────────────────────────────────────────────────┐
│ 3. TOTAL COST OPTIMIZATION │
│ Not just piece price - total cost of ownership │
│ PPV, logistics, inventory, quality costs │
└─────────────────────────────────────────────────────┘
Critical Rule: Never compromise quality or delivery for cost. A cheap part that stops the line costs far more than the savings.

Cost Management Strategies
Total Cost of Ownership (TCO)
PIECE PRICE
+ Tooling (amortized)
+ Logistics (freight, handling, duties)
+ Inventory carrying cost
+ Quality costs (inspection, sorting, returns)
+ Administrative costs (POs, invoices, management)
+ Risk premium (single source, geopolitical)
─────────────────────────────
= TOTAL COST OF OWNERSHIP
Cost Reduction Levers
| Lever | Description | Typical Savings | |-------|-------------|-----------------| | Volume Leverage | Consolidate spend, longer commitments | 3-8% | | Specification Review | Over-engineering elimination | 5-15% | | VA/VE | Value Analysis / Value Engineering | 10-30% | | Should-Cost | Detailed cost breakdown analysis | 5-20% | | Resourcing | Geographic arbitrage, new suppliers | 10-25% | | Process Improvement | Supplier manufacturing efficiency | 3-10% | | Payment Terms | Extend terms, capture early pay discount | 1-3% |
Should-Cost Model Components
MATERIAL COST
Raw material × Usage factor × Scrap factor
+ Market pricing or index
CONVERSION COST
Labor: (Cycle time × Labor rate) / Efficiency
Machine: (Cycle time × Machine rate) / OEE
OVERHEAD
SG&A: % of conversion
Profit: % margin (typically 5-15%)
LOGISTICS
Packaging + Freight + Duties
Negotiation Framework
Preparation Checklist
- [ ] BATNA - Best Alternative to Negotiated Agreement
- [ ] ZOPA - Zone of Possible Agreement
- [ ] Supplier economics - Their costs, margins, pressures
- [ ] Market conditions - Supply/demand, commodity trends
- [ ] Leverage points - Volume, specification, competition
- [ ] Walk-away point - Clear bottom line
- [ ] Value creation opportunities - Win-win possibilities
Multi-Variable Negotiation
Don't negotiate price alone. Trade across multiple variables:
| Variable | Give | Get | |----------|------|-----| | Volume commitment | Higher volume | Lower price | | Contract length | Longer term | Price protection | | Payment terms | Earlier payment | Discount | | Specification | Relax tolerance | Cost reduction | | Logistics | Different Incoterm | Price adjustment | | Quality | Accept more inspection | Cost pass-through |
BATNA Development
Always have alternatives:
- Identify backup suppliers (at least 2)
- Understand switching costs and timeline
- Maintain relationships with alternatives
- Document qualification status
- Never reveal desperation

| Probability | Low Impact | Medium Impact | High Impact | |-------------|------------|---------------|-------------| | High | Monitor | Mitigate | Urgent Action | | Medium | Accept | Monitor | Mitigate | | Low | Accept | Accept | Monitor |
Materials Planning
Inventory Strategy by Part Type
| Part Type | Strategy | Target DOS | |-----------|----------|------------| | A Items (High value, critical) | JIT, frequent delivery | 3-5 days | | B Items (Medium value) | Weekly delivery, safety stock | 7-14 days | | C Items (Low value, commodity) | VMI, consignment, bulk | 30+ days | | Critical spares | Buffer stock regardless of value | Per risk |
Safety Stock Calculation
Safety Stock = Z × σ × √(LT + Review Period)
Where:
Z = Service level factor (95% = 1.65, 99% = 2.33)
σ = Demand standard deviation
LT = Lead time in periods
MRP Best Practices
- [ ] Accurate BOMs (99%+)
- [ ] Realistic lead times (include buffer)
- [ ] Clean inventory records (cycle count)
- [ ] Demand forecast accuracy tracking
- [ ] Exception management daily
- [ ] Planner workload balancing
