What are expert systems?

In many organizations, specialist knowledge is often present in a fragmented way or ‘hidden’ in the minds of employees. As a result, organizations do not fully benefit from the knowledge available. Thanks to expert systems, this is a thing of the past. By using expert systems, organizations are able to centralize specialist knowledge and make it practically applicable for a large group.


Expert systems are applications that help users make decisions or support users by giving expert advice. In practice, an expert system is often presented in the form of an application in which the end user is given the opportunity to answer simple questions and, if necessary, enter additional data. In the background, the end user is then guided to the right outcome based on one’s input by means of a decision tree. That means that in the future, colleagues (with less substantive knowledge) can also benefit from the knowledge in your organization and make the right decisions.

Obviously, experts with domain knowledge are usually responsible for the creation and management of expert systems. After all, they are best able to determine what knowledge is required and what criteria must be observed in order to come to the right outcomes. That is why we also regularly call expert systems knowledge systems.

What are expert systems used for?

Expert systems are available in many shapes and sizes. The common denominator is that expert systems are mainly used in organizations in which certain specialist knowledge is only available to a limited number of people. Organizations using expert systems include governmental organizations, legal service providers, healthcare institutions as well as regular companies.

By using expert systems, knowledge use within these organizations can significantly be broadened and support is offered when realizing various objectives. For example, organizations use expert systems to reduce costs, increase efficiency, improve services, and comply with current laws and regulations.

Expert systems are typically the foundation of applications like:

  • Advice tools
  • Risk analyses
  • Document generators
  • Calculation modules
  • Tools to check legislation and regulations
  • Compliance checks

Advantages of expert systems



By making the knowledge in your organization widely available and practically applicable, people with less substantive knowledge can also use it in the future.



The repeatedly applied logic guarantees uniformity in working methods, processes, and decisions. Outcomes are no longer subject to personal interpretations and/or experiences.
