Oracle Real-time Decisions (RTD) software optimizes customer interactions across multiple channels like web, call centers, and mobile in real-time. It recommends products and services for each interaction based on factors like call reason, agent skills, and time of day. RTD automatically learns and adjusts its recommendations based on feedback to continuously improve results. It integrates across channels and is more advanced than rule-based systems. The document then provides an example of how RTD could optimize interactions with a specific customer, Robert Knowles, during a call about account fees.
