In the future, success or failure of an enterprise will more and more depend on its ability to flexibly and quickly react to changes at the market, the development, or the manufacturing side. This means that the flow of work within a department, within a company, or even across companies may have to be quickly adapted. To meet this challenge enterprises are developing a growing interest in supporting their business processes more effectively and in streamlining their computer applications such that they behave "process-oriented".

In principle, workflow (WF) technology offers a promising approach for this. It allows to define processes explicitly, to integrate application components, and to deliver a state-aware control service. However, current WF technology is jumping much too short. After being implemented, processes are rather inflexible and later changes in the process schema cannot be mapped to running instances. These and other weaknesses limit the applicability of WF technology significantly and will lead to big headaches for its users.

The target of the ADEPT project is to develop the fundamentals for a WF technology which makes process-aware applications easy to implement and which is much more flexible than today's systems. Very challenging in this context is to achieve this in an efficient manner and without violating consistency and robustness.

In my talk, I will describe the demands for adequate WF technology and illustrate the "technological vision" we are trying to make reality in our research. I will also discuss the technological approaches taken in the ADEPT project in order to meet these goals. Among other things, I will present the developed framework for dynamic WF changes, which enables both, the quick and correct propagation of WF type changes to in-progress WF instances and the ad-hoc adaptation of single WF instances.

The presentation will be complemented by a life demonstration of the experimental ADEPT process management system and the schema evolution and process instance migration facility, which will be part of the ADEPT2 process management system which is currently under implementation at the University of Ulm.
