The worldwide customer care software market is forecast to grow from USD3.6 billion in 2013 to USD5.4 billion in 2018, at an 8.7% CAGR. Communication service providers (CSPs) need to increase ARPU and reduce churn. This is driving significant innovation by vendors in the customer relationship management (CRM) and customer interaction sub-segments to enable CSPs to introduce self-service capabilities and generate a holistic view of customer needs through better data collection and management.
