A conversation with Gene Long, president of UPS Supply Chain Solutions Consulting Services, Atlanta. Gene Long has spent most of his 32-year career on the shipper side of the supply chain fence, including service as director of worldwide logistics for Dell Computer. At Dell, Long was responsible for physical distribution, remote inventory and delivery activities in North and South America, Europe and Asia. He earlier served as vice president of global logistics for Burlington Air Express, where he created a third-party logistics company serving clients around the world. Since joining UPS in 2001, Long has been deeply involved with the company's strategy to expand its portfolio of supply chain services through targeted acquisitions.
