As part of Alterian’s Adaptive Customer Experience™ Platform, ‘Chameleon’, Dynamic Decision Engine (DDE) adapts to every customer interaction in real-time with in-the-moment personalization on any channel such as real-time email content or website content and unknown to known identity stitching. DDE requests the necessary full slow (historical) and fast (in-the-moment) data of each customer to personalize the experience as each interaction is happening in less than 100 milliseconds. Now every interaction is immediately informed by the previous interaction for future messaging.
