The global integration of IBM's supply chain serves as the foundation for two principles, or axes, underpinning the company's service philosophy. The first is what Carroll terms the "pillars of strength." The supply chain organization, he says, provides strength and stability to the company because there are uniform practices at its centers for procurement, manufacturing, and order fulfillment around the globe. For example, all fulfillment centers, regardless of location, follow a standard procedure for taking orders or handling cash collection. "The driving force is to 'do it once, consistently' around the globe," he observes.
