Change Support Feature FF2: Support for Instance-Specific Changes

To deal with exceptions PAISs must support unplanned changes (Design Choice F2[1]) at the process instance level either through high-level changes in the form of patterns or through low-level primitives. To deal with uncertainty, PAISs must further allow process modelers to keep parts of the model unspeci ed during build-time and to defer the concretisation of the respective part to run-time (Design Choice F2[2]). The e ects resulting from instance-speci c changes can be permanent or temporary. A permanent instance change remains valid until completion of the instance (unless it is undone by a user). By contrast, a temporary instance change is only valid for a certain period of time (e.g., the current iteration of a loop).
