Partner with Finance to connect the demand/supply plan to revenue, margin, and working-capital outlooks (dealer floor plan, inventory turns).
Build what-if and scenario models for demand shifts, supply disruptions, and capacity constraints to inform contingency planning.
Assess the operational impact of tariff exposure (Section 232 / 301 / IEEPA), FX volatility (KRW/USD/CAD), and input-cost movements on plan and inventory.
