What OEM Supply Chain Consulting Covers
- Resilience. Multi-sourcing, regional options, inventory guardrails, and control towers informed by real-time data. See McKinsey’s risk survey.
- Cost. Cost-to-serve modeling by product and customer, plus vendor and logistics optimization. Overview from Gartner.
- Quality. Supplier PPAP and APQP cadence, incoming inspection, and field-return loops linked to corrective action.
- Delivery. OTIF improvement through schedule adherence, buffer design, and constraint removal.
- ESG. Scope 3 data, supplier engagement, and EU CSRD alignment as reporting phases in from the 2024 financial year. See the European Commission CSRD page.
Why Now
The Cost of Resilience Mindset
Leading OEMs balance cost and agility using a cost of resilience lens. The aim is flexible networks that can absorb shocks without eroding margin. See BCG’s July 2025 perspective and the World Economic Forum’s 2024 report.

A 90-Day OEM Playbook
- Day 0 to 15: Baseline and guardrails. Freeze the cost and service baseline with finance, define service and margin guardrails, and map top supplier and lane risks.
- Day 1 to 30: Diagnostics. Run cost-to-serve by SKU and region, perform supplier concentration analysis, and review quality escapes and field returns.
- Day 31 to 60: Two pilots. Launch a dual-sourcing or buffer pilot on a tier-one component and remove one recurring logistics constraint. Track OTIF, premium freight, and rework hours.
- Day 61 to 90: Scale and policy. Negotiate new supplier options, formalize inventory guardrails, publish a weekly dashboard, and start Scope 3 supplier requests aligned to CSRD timing.
