Supply Chain Management - Automotive Manufacturing When to Activate This Skill "Help me negotiate with [supplier]" "Create an RFQ for [component]" "Supplier scorecard for [vendor]" "Should-cost analysis for [part]" "Make vs buy decision for [process]" "Category strategy for [commodity]" "Reduce BOM cost by [target]" "Supplier quality issue with [vendor]" "Materials planning for [product]" "Inventory optimization" 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.
