An Executive Information System (EIS) is a Decision Support System (DSS) used to assist senior executives in the decision making process. It does this by providing easy access to important data needed to achieve strategic goals in an organization. An EIS normally features graphical displays on an easy-to-use interface. It can be used in many different types of organizations to monitor enterprise performance as well as to identify opportunities and problems.
The executive information system plays a very important role in obtaining the data from the different sources, then help in the integration and the aggregation of this data. After performing these steps the resulting information is displayed in such a pattern that is very easy to understand. With the help of all this, top-level executives get a great support when making strategic and operational decisions.
