An expert system mimics the reasoning of a human expert, drawing from a base of knowledge about a particular subject area to come to a decision or recommendation. To build an expert system, developers work with experienced and specialized professionals as they provide answers to questions and explain their reasoning processes. The output is fine-tuned continually as the experts contribute more knowledge to the base, refine the rules, and add additional questions. The process is challenging, often because experts don't quite know exactly how they reach their conclusions. Formally identifying the actual steps is harder than it appears, but the results can be quite dramatic and enormously useful for decision support.
