Process-aware information systems (PAISs) must not implement business processes in a rigid manner, but allow authorized users to deviate from the implemented workflows on-the-fly and to dynamically evolve them over time if required. 

While there has been a lot of work on the theoretical foundations of dynamic process changes, there is still a lack of PAISs actually implementing respective features. Designing the architecture of an adaptive PAIS, however, constitutes a big challenge due to the high complexity emerging in the context of dynamic process changes. Besides this, non-functional requirements like performance, robustness, extensibility, security and usability must be met by the PAIS. 

In his PhD thesis project, Ulrich Kreher has realized a holistic approach to master this complexity. Based on a conceptual framework for adaptive process management, which was developed in the Opens internal link in current windowADEPT1 and Opens internal link in current windowADEPT2 research projects, he has designed an advanced architecture for next generation process management technology. The thesis discusses major system requirements and basic architectural principles, gives insights into selected system components and concepts, and shows how various kinds of dynamic changes can be realized in an integrated and efficient manner.

Ulrich’s thesis was created in the context of the Opens internal link in current windowADEPT2 research project. Its results are fundamenal for the AristaFlow BPM Suite. This next generation process management technology  has been successfully  distributed on the BPM market by the Opens external link in new windowAristaFlow GmbH – a spin-off of our institute -- for several years.

BPM is not just about making diagrams. The real challenge is to realize information systems that support processes without jeopardizing flexibility.

The measure of intelligence is the ability to change.

It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is most adaptable to change.
