Poor customer service isn’t a headache just for consumers; it’s a problem that vexes senior managers too. Balancing the trade-offs between the cost of services and the customer experience benefits they provide is difficult. Ensuring that frontline workers can efficiently and consistently execute service offerings across a far-flung organization is harder still. Along the way, many companies lose sight of what makes human beings tick—for instance, by overlooking well-known principles of behavioral science when delivering services—and thus unwittingly predispose customers to dissatisfaction.

At the same time, the customer service landscape is changing as social media and new mobile phone technologies give companies unprecedented access to data on customer interactions, while the technologies are changing the nature of the interactions themselves—for example, by amplifying the speed and impact of customer complaints.
