James Taylor's Decision Management

After my posts on event processing (this one and this one), Opher posted a thoughtful response in which he asked a question about decisions tied to events and decisions not tied to events.
What I mean here is that there are decisions that would not change even if I changed the sources of events, the definitions of events or the information on events. These business decisions are certainly tied to complex events in the sense that events trigger them but they are distinct from the decisions that relate specifically to the management of the event stream itself, correlation of events etc. The decisions that are tied to the event definitions would have to be redefined whenever the events are changed. Business decisions - who is a good customer, for instance - also change but on their own schedule and not just because the event cloud changes.
