Using "expert systems" for competitive advantage

It is possible to create simple, yet powerful computer applications that provide a competitive advantage with little cost and low risk. The best way to get started with expert systems is to select a high-potential application, start small, and grow the system. Creating an expert system requires 3 essential ingredients: 1. technology resources in the form of a personal computer, an expert system shell, and a designer eager to try something new, 2. an expert who is willing to share his/her knowledge with the designer, and 3. an application that is suitable for expert system technology and has the potential for providing a competitive advantage.
