As part of further research, one could attempt to obtain the executives' impressions directly. Many of these benefits are related to improved access, preparation, delivery and presentation of executive information. EISs are said to improve the effectiveness of the executives. Not only do they save executives' time and improve their performance, but they also support the accomplishment of strategic business objectives. Obtaining information is key for the interpersonal role, and the benefits related to environmental scanning and improving executives' effectiveness serve this purpose very well.
Benefits related to information serve the informational role of the manager.
The benefits under the categories of meeting strategic objectives and economy serve the decisional role of the manager. Thus, for developing a successful EIS, one may use our results as a guide or to augment new research findings2. The University of Georgia, Athens, Georgia, December 1993.
