The document discusses a shift from the traditional 40-year-old paradigm of customer service centered around automatic call distribution (ACD) systems to a new paradigm enabled by technologies like mediated interaction matching (MIM). MIM uses customer and agent data to match them for personalized interactions. It implements analytics-assisted routing (AAR) and customer choice routing (CCR) to improve the customer experience. The new paradigm also moves beyond call centers to use field experts and mobile technologies to build local relationships through in-person interactions.
