This document discusses how Go-Ahead Group has adapted its marketing and customer service to be multi-channel, connected, and responsive to mobile disruption. It started with providing real-time information at stations, then expanded online and through mobile apps and websites. Now the focus is on social, mobile, and real-time engagement led by customer needs. Challenges include proving value across channels, reducing costs, understanding offline customers, and attributing revenues across channels. The key is thinking small by focusing on customer needs and then connecting the channels.
