Pre-Modelled Flexibility for Business Processes

Abstract

At process-aware information systems (PAIS), sometimes, a flexible deviation from the rigidly designed process becomes necessary. Otherwise the users would be restricted too much. This paper presents an approach that allows to define the expected flexibility requirements only once already at build-time and apply them at run-time in the PAIS. Compared to dynamic changes during run-time, this has the ad-vantage that the usage of the pre-defined information reduces the effort for the end users at each devia-tion. In addition, applying flexibility becomes saver; e.g., since user rights can be defined. This paper presents the corresponding requirements, with a special focus on the kind of information that has to be pre-defined at build-time. Thereby, all relevant process aspects were respected and the necessity of the requirements is illustrated with examples from practice.
