The document discusses how organizations are establishing Social Business Centers of Excellence (COEs) to better coordinate their social media strategies and initiatives across business units. It provides examples of how COEs at large companies like Shell function. COEs establish shared goals and standards to avoid duplicated efforts. They also develop tools and best practices that can be used across business units while allowing for customization. Establishing COEs helps companies leverage social media at scale through a unified vision and collaborative approach rather than competing initiatives within silos.
