JT has posted his view on rules and decisions and how they relate. Given that James talks more about services than events, I thought it would be worth reviewing his post from both a Complex Event Processing and a TIBCO BusinessEvents event processing platform perspective.

”Decision Services: Support business processes by making the business decisions that allow a process to continue. Support event processing systems by adding business decisions to event correlation decisions (they are often called Decision Agents in this context). Allow crucial and high-maintenance parts of legacy enterprise applications to be externalized for reuse and agility. Can be plugged into a variety of systems using Enterprise Service Bus approaches.”
