One of the critcal issues in Managment Information System (MIS) is the information overload from complicated hierachical menu. Novice users easily get lost when an important and frequently used menu item is rooted and hidden in a deeper level of a poorly designed menu interface. Therefore, usability of menu interface critically affects the quality of MIS applications. This paper developed an approach by integrating Cognitive Walkthrough procedure and automated logging to automatically generate intelligent and dynamic menu to accomodate different needs in different tasks for different types of users. Through this approach, the contents and structures of the menu are adaptive to the usage context. A pilot study was also conducted to evaluate the overall usability issues and effectiveness of the intelligent menu. It was revealed in the preliminary results that the intelligent menu interface could sigificantly reduce the time for menu search per task which is otherwise required in searching a normal non-intelligent menu interface. The total time for accomplishing a set of sequential and pre-defined routine tasks was also reduced by a significant amount.
