ABSTRACT = {Workflow management aims at modeling and executing application processes in complex technical and organizational environments. The technical environment in modern information system infrastructures is often characterized by object-oriented application systems. These systems consist of application objects which collaborate to achieve a common goal. Typically, application objects are modeled using object-oriented design languages like the Unified Modeling Language (UML). On the other hand, workflow modeling is typically performed using propriatory workflow languages. Hence, two separate formalisms are present for modeling application objects and workflows. In this paper we try to remedy this situation by proposing the use of an extension of the UML to allow workflow modeling, thereby providing a seamless integration of workflow functionality in object-oriented application systems. The formalism is also helpful to deal with all relevant aspects of modeling complex workflow systems in an overall scalable and consistent manner.}
