An Expert system can not give creative solutions and can be costly to maintain. By getting in early, an organization can gain experience and develop technical staff, thereby creating a barrier competitors will have a hard time overcoming. Moreover, even the most advanced expert systems, such as XCON, do not replace experts but rather augment their capabilities or allow less-experienced individuals to perform better. Issues that take days to resolve are probably too ambitious. Thus, today’s ground-breaking ES may be tomorrow’s traditional solution. …the best expert always did the job? This component is also helpful for formulating conclusions. His recent research interest is in expert systems.

Their experience shows that expert systems are indeed a valuable tool for capturing and disseminating skill and knowledge, often to create competitive advantage. 2 For discussion of realistic expectations, see, for example, Beau Sheil’s “Thinking About Artificial Intelligence,” HBR July–August 1987, p. 91. This particular expert system is very specific for small business loans. The knowledge base is a repository of facts. For example: Then investment in high-growth stocks is strongly recommended. ESs, however, are developed via rapid prototyping—that is, the quick production of a preliminary version whose use provides feedback for correcting the design. Digital managers attribute to XCON some $25 million of the savings realized from minimizing the final assembly and test process. Digital couldn’t afford to have its design engineers configuring computer systems, even though they understood the process best. Most systems are custom built, and even the few available turnkey systems often need customization. So how does a manager court the new technology?

The technical editors at Digital couldn’t use the first version of XCON. If, however, the MIS department has a history of supporting and implementing user-initiated systems and can attract the necessary talent, then giving MIS a major role in the ES development project is probably a good idea. By using an ES called Mentor to help diagnose problems with commercial air conditioning systems, Honeywell ensures that the quality of service calls is uniformly high. They are not being intentionally evasive. DENDRAL: Expert system used for chemical analysis to predict molecular structure. These projects require a team of people with the right mix of talent and take from six months to at least two years to create and implement. If a human expert is hired away or is too busy to teach younger colleagues, an ES can help by serving as a training tool. Suddenly the company could differentiate itself from competitors.

They sat three experts on one side of a table, a novice with all the data on the other, and put a curtain down the middle. As with decision support systems, prototyping ESs involves choosing the relevant data, presentation mechanisms, and analytical models. Computers removed clerical staff in industries like insurance. Targeting a particular task doesn’t always tell you who the system users will be, because actual usage often diverges from the plan. Example # 1.
