CRH implemented Yammer to create a social intranet for their 76,000 employees across 3,500 locations. They took a slow, bottom-up approach over 3 months to pilot Yammer and encourage voluntary adoption. Their goals were to improve connectivity across the large, decentralized organization, break down silos, and shift to more two-way and real-time communication. They integrated Yammer and SharePoint to provide a central social and document collaboration platform. Training and identifying employee champions were key to driving adoption of the new social intranet platform.
