Change Support Feature FF6: Change Reuse

In the context of unplanned instance changes "similar" deviations (i.e., combinations of one or more adaptation patterns) can occur more than once. As it requires signi cant user experience to de ne changes from scratch, change reuse has to be supported. For this, changes should be annotated with contextual information (e.g., about the reasons for the deviation) and be memorized (Change Feature F4[2]). This contextual information can be used for retrieving similar problem situations. This approach ensures that only changes relevant in the current situation are presented to the user. Regarding patterns for changes in prede ned regions, reuse can be supported by making historical cases available to the user and by saving frequently re-occurring instances as templates.
