This document discusses emerging trends in customer service, termed "Customer Service 4.0". It identifies five key trends: 1) the rise of social CRM and using social media for customer interactions, 2) a shift to cross-channel customer service over separate channels, 3) a focus on customer experience management, 4) using "mashups" to combine customer data from various sources, and 5) greater collaboration between companies and customers. The document argues that companies must react to these paradigm shifts by collaborating more closely with customers at every stage of the customer experience life cycle.
