A social CRM case study presented by Yaelle Teicher (Community Manager, Voyages SNCF) at Our Social Times' Social CRM 2011 Paris conference. In 2006, Voyages-sncf.com launched it's mobile website www.voyages-sncf.mobi with the objective of creating an innovative new way of booking train journeys. In addition to this, Voyages-sncf.com has developed an operational approach to anticipating and responding to the needs of customers. As a result, social media has become a highly productive space for expression and dialogue for Voyages-sncf.com customers.
