“…Exception handling often requires combined use of such patterns resulting in rather complex routines. The Exlet approach [41], for example, addresses this problem by allowing for the combination of different exception handling patterns to an exception handling process called Exlet. Similarly, [42] suggests the usage of meta workflows for coordinating exception handling.…”

Abstract. Process-aware information systems (PAIS) must be able to deal with uncertainty, exceptional situations, and environmental changes. Needed business agility is often hindered by the lacking flexibility of existing PAIS. Once a process is implemented, its logic cannot be adapted or refined anymore. This often leads to rigid behavior or gaps between real-world processes and implemented ones. In response to this drawback, adaptive PAIS have emerged, which allow to dynamically adapt or evolve the structure of process models under execution. This paper deals with fundamental challenges related to structural process changes, discusses how existing approaches deal with them, and shows how the various problems have been exterminated in ADEPT2 change framework. We also survey existing approaches fostering flexible process support.

“…As academic approaches we consider popular flexible PAIS such as ADEPT2 [11,39], CAKE2 [30,40], CBRFlow [41,42], HOON [17], MOVE [18], Pockets of Flexibility (PoF) [16,43,44], WASA2 [13], WIDE [45,46], Worklets/Exlets [12,47,48], and YAWL [49]. -Feature Identification Procedure.…”

Companies increasingly adopt process-aware information systems (PAISs), which offer promising perspectives for more flexible enterprise computing. The emergence of different process support paradigms and the lack of methods for comparing existing approaches enabling PAIS changes have made the selection of adequate process management technology difficult. This paper suggests a set of 18 change patterns and 7 change support features to foster the systematic comparison of existing process management technology in respect to process change support. While the proposed patterns are all based on empirical evidence from several large case studies, the suggested change support features constitute typical functionalities provided by flexible PAISs. Based on the proposed change patterns and features, we provide a detailed analysis and evaluation of selected approaches from both academia and industry. The presented work will not only facilitate the selection of technologies for realizing flexible PAISs, but can also be used as a reference for implementing flexible PAISs.

“…With such semantic clarity, it is possible to verify processes in advance before enactment for runtime soundness [3], i.e., one can check for control-flow issues such as deadlocks. In YAWL, workflow adaptations are possible through so-called worklets [8] enactment in a dynamic way based on the evaluation result of Ripple-Down-Rules (RDR) trees. The now industrial AristaFlow system [90] is another example originating from research based on the former ADEPT flow system [89].…”
