One of our major research interests is the systematic comparison of different PAIS-enabling technologies.


Catalogue of Change Patterns and Change Support Features


To foster the qualitative comparison of different frameworks for process flexibility we proposed a catalogue of change patterns and change support features.

The patterns were identified by analyzing more than 150 process models from both the healthcare and the automotive engineering domain. The identified patterns allow to

  • effectively deal with exceptions,
  • cope with the evolving nature of business processes and
  • support users to better deal with uncertainty by deferring decisions to run-time.

Empirical Evaluation of Process Flexibility


Our group is also very interested in the empirical evaluation of process flexibility.


Alaska Simulator

Alaska Simulator is an interactive software tool developed at the University of Innsbruck which allows people to explore different approaches to process flexibility by using a familiar metaphor, i.e., travel planning and execution.

Alaska Simulator supports

  • students in testing, analyzing and improving their planning behavior by using different approaches to process flexibility
  • the comparison of strength and weakensses of different approaches to process flexibility as well as
  • the investigation of research questions in the area of flexible business processes

Alaska Simulator is the first tool providing integrated support for decision deferral patterns (i.e., Late Binding, Late Modeling and Late Composition) fostering the systematic comparison of their strengths and weakensses in a training environment.



A detailed description of Alaska Simulator can be found at http://alaskasimulator.org. For a description of an experiment using Alaska Simulator read "The Declarative Approach to Business Process Execution: An Empirical Test".


CHEETAH project

In the CHEETAH project we transfer ideas from Alaska Simulator by developing a platform for the systematic comparison of different approaches to process flexibility. While Alaska Simulator relies on a journey metaphor and provides an environment for students to easily being engaged in, the CHEETAH platform is independent of this metaphor and thus has a broader scope.


Workflow Management versus Case Handling

Our paper "Workflow management versus case handling: results from a controlled software experiment" is also related to the empirical evaluation of PAIS-enabling technologies and compares workflow management technologies and case-handling in the context of a controlled experiment.

Assessing the Suitability of Notational Systems for Process Modeling


Together with Jan Mendling (Humbold Univ. zu Berlin), Hajo Reijers (Technical University of Eindhoven) and some other colleagues we started to investigate the research question "Which notational system for process modeling is most suitable in a particular context".

So far two workshop papers emerged from this cooperation:

  • D. Fahland and J. Mendling and H. Reijers and B. Weber and M. Weidlich and S. Zugal: Declarative versus Imperative Process Modeling: The Issue of Maintainability. Accepted for ER-BPM'09, held in conjunction with BPM'09 in Ulm.

  • D. Fahland and D. Lübke and J. Mendling and H. Reijers and B. Weber and M. Weidlich and S. Zugal: Declarative versus Imperative Process Modeling: The Issue of Understandability. In  10th Workshop on Business Process Modeling, Development, and Support (BPMDS 2009) and 14th International Workshop on Exploring Modeling Methods in Systems Analysis and Design (EMMSAD 2009), Lecture Notes in Business Information Processing Volume 21.
