List four advantages of using an Expert System in decision making.

Advantages of expert systems in decision-making:
1. Enable high quality decisions to be made.
2. They reduce the number of decision makers since they partly automate the process of decision-making. This implies lower labour costs.
3. They ensure accountability since they provide reasons for proposing an action.
4. Since they support managers in decision-making, they enable decisions to be made within a short time period.
5. Since expert systems capture human expertise, they enable organizations to fully retain intellectual resources for future decision-making.
