David Rieger

I am a senior supply chain and operations executive with more than 30 years of leadership experience across manufacturing, automotive, industrial products, and consumer goods. I help organizations stabilize operations, improve supply chain performance, release working capital, scale for growth, and build sustainable operating systems. My experience spans S&OP/SIOP, materials planning, procurement, supplier performance, inventory optimization, logistics, warehousing, manufacturing operations, ERP/MRP, Lean/Toyota Production System, and large-scale transformation. At McNeilus Truck Manufacturing, I led a 109-person Materials organization across a 175-acre, eight-building operation, managing inventory portfolios up to $165M with approximately 3.8 annual turns—representing roughly $600M+ in estimated annual material flow. I reduced inventory by $32.9M while supporting 20% business growth. I have also led major automotive manufacturing launches and approximately $20M in supply chain transformation initiatives, redesigned material-flow and logistics systems, implemented Lean/TPS operating practices, and delivered significant improvements in inventory, service, cost, capacity, and operational performance. As a fractional executive, I am best suited for organizations that need an experienced operator to quickly assess what is happening, establish priorities and accountability, solve complex supply chain or operational problems, and turn strategy into execution. My leadership style is hands-on, collaborative, data-driven, and focused on leaving behind stronger processes, systems, and teams.
