Today's supply chains -- stretched by globalization, outsourcing, and the rapid proliferation of SKUs and product configurations -- are exceedingly complex. They're also exceedingly hard to manage. Companies know that in order to provide customers with more customization, more service, and more intimacy than ever, they need to segment their supply chain. But most still rely on a "one-size-fits-all" approach. The future belongs to companies who can reliably and profitably match their supply chains to the specific needs of their customer segments. Leaders will win their markets by enabling the operations that can support a highly segmented, scalable supply chain.
