Analyst Insight: A perfect performance means playing the right song for the right audience. This even applies to supply chain. When supply chain is one-size-fits-all, the orchestra falls out of tune, compromising quality to try to satisfy everyone. To deliver the best performance consistently, businesses need to prioritize customer demands through segmentation and synchronization. This reassembles supply chain to place customer needs at the core, allowing harmony between the business and customer. - Rodrigo Cambiaghi, Principal; Claudio Menegusso, Senior Manager; and Carolyn Dombrowski, Consultant, all with Advisory Services of Ernst & Young LLP
