Figure 9.2 Process vs. Decisions vs. Rules Engine
A rules engine splits up the decision logic into two parts: the actual decision itself
and how that decision is made. With th e use of a rules engine, you can input a
bunch of facts about the current situation, they swirl around inside a black box,
and out comes a proposal as to what decision you should make—which then gets
approved or rejected by something, be it a human or a machine.
