Robust and Flexible Error Handling in the AristaFlow BPM Suite

Process-aware information systems will be not accepted by users if rigidity or idleness due to failures comes with them. When implementing business processes based on process management technology one fundamental goal is to ensure robustness of the resulting process-aware information system. Meeting this goal becomes extremely complicated if high flexibility demands need to be fulfilled. This paper shows how the AristaFlow BPM Suite assists process participants in coping with errors and exceptional situations in a flexible and robust way. In particular, we focus on novel error handling procedures and capabilities using the flexibility provided by ad-hoc changes not shown in other context so far.
