The birth of Expert System Technology occurred over thirty years ago with the introduction of 'Dendral' to the chemical industry. Since then over 12,500 expert systems have been developed for many different types of application. This paper examines several of these systems and uses the resulting analysis to identify eight key benefits that expert system technology can afford the Insurance Industry. Further to this identification, the paper suggests a product ideally suited to incorporate such benefits, and documents the method for developing such a product. Finally, having established the necessity of the Insurance Industry to embrace expert system technology, the paper examines the importance of this technology within the commercial sector in general, where it is concluded that it has a significant role to play both now and in the future.
