Process flexibility is a vital part for almost any business area. Change logs are a central asset for documenting adaptations in processes, since they capture key information about associated change operations. Comparing multiple change operations others interesting data for many analysis questions, e.g., for analyzing previously applied change operations and for supporting users in future adaptions. In this paper, we discuss different change perspectives and present metrics for comparing change operations. Their applicability and feasibility are evaluated based on a prototypical implementation and based on real world process logs.
