Furthermore, the chapter explores the verification of process models and the assurance of their correct executability before deploying them to the PAIS run-time environment. Finally, it elaborates on the enactment of process instances and the coordination of corresponding activities at run-time as specified in the process model.

Ad hoc Changes of Process Instanceshavior of a process instance can be situationally adapted, and presents adaptation patterns that may be applied for this purpose. Moreover, it is shown how PAIS robustness can be ensured when dynamically adapting process instances, and how end-users can be assisted in defining ad hoc changes.

However, to cope with the dynamic nature of business processes, PAISs not only need to be able to deal with exceptions, change the execution of single business cases on the fly, efficiently deal with uncertainty, and cope with variability, but must also support the ev

For coping with such anticipated exceptions, exception handlers are typically provided by process designers at build-time. These
