Why is expert system important?
Expert systems are capable of handling enormously complex tasks and activities as well as an extremely rich knowledge-database structure and content. As such, they are well suited to model human activities and problems. Expert systems can reduce production downtime and, as a result, increase output and quality.
How are expert systems made?
How are expert systems created? Experts in a field are interviewed and their knowledge is collected. All of the knowledge collected from the experts is organised and stored in the knowledge base. This allows the knowledge base to be searched by the user.

How do expert systems work?
Expert systems do not have human capabilities. They use a knowledge base of a particular domain and bring that knowledge to bear on the facts of the particular situation at hand. The knowledge base of an ES also contains heuristic knowledge – rules of thumb used by human experts who work in the domain.
