SUPPLY CHAINS: the place where old-economy transportation meets new-economy technology. In 1869, Leland Stanford drove the Golden Spike into the ground in Utah, creating the first coast-to-coast railroad. The railroads supported billion-dollar modern-dollar fortunes for owners like the Vanderbilts, Carnegies and Flaglers. One century later, in 1956 Malcolm McLean invented containerization, enabling not just modern steamships but also global retail powerhouses like Walmart. Today, we have entered the third wave of value creation. Instead of railroads and steamships, the new-economy supply chain leaders have learned how to harness the power of technology. SUPPLY CHAINS explores this intersection, evaluates the trends, and looks into the future.
