Architectural Design of Flexible Process Management Technology

Abstract

To provide effective support, process-aware information systems (PAIS) must not freeze existing business processes. Instead they should enable authorized users to deviate on-the-fly from the implemented processes and to dynamically evolve them over time. While there has been a lot of work on the theoretical foundations of dynamic process changes, there is still a lack of PAIS implementing this dynamics. Designing the architecture of respective technology constitutes a big challenge due to the high complexity coming with dynamic processes. Besides this, performance, robustness, security and usability of the system must not be affected by the added flexibility. In the AristaFlow project we have taken a holistic approach to master this complexity. Based on a conceptual framework for flexible process enactment and dynamic processes, we have designed a sophisticated architecture for next generation process management technology. This paper discusses major design goals and basic architectural principles, gives insights into selected system components, and shows how change support features can be realized in an integrated and effective manner.
