Recently, a new generation of adaptive Process-Aware Information System (PAIS) has emerged, which enables dynamic service changes (i.e., changes of instances derived from a composite service and process respectively). This, in turn, results in a large number of process variants derived from the same process model, but differing in their structure due to the applied changes. Since such process variants are expensive to maintain, the process model should evolve accordingly. It is therefore the authors' goal to discover those activities that have been more often involved in process (instance) adaptations than others, such that they can focus on them when redesigning the process model. This paper provides two approaches to rank activities based on their involvement in process adaptations and process configurations respectively.
