Red Hat Decision Manager provides a vast array of decision management functionality — from the decision tables feature in the new Decision Model and Notation (DMN) v1.1, which implements the full FEEL Compliance Level 3 of the DMN specification, to Predictive Model Markup Language (PMML).

Another powerful feature is the Complex Event Processing (CEP) engine. This engine provides the ability to detect, correlate, abstract, aggregate, compose, and react to events. In other words, the technology provides techniques to infer complex events from simple events, react to the events of interest, and take actions. The main difference between CEP and normal rules execution is the notion of time. Where standard rules execution in the Decision Manager deals with facts and reasoning over these facts, the CEP engine focusses on events. An event represents a significant change of state at a particular point in time or interval.
