An important tool in object oriented development is the concept of use case modeling. This modeling tool necessitates an external view of an organization or the MIS services of organization from the perspective of an actor. An actor can be an external entity such as a customer or vendor, or an internal entity such as a manager or end user. This paper discusses use case modeling as an important planning framework in management information system courses. Definitions of important terms are provided. Techniques are presented for employing use case modeling in reengineering and global case studies. A simple example of a college registration system and a more complex example of a global case study are presented.An important tool in object oriented development is the concept of use case modeling.
