Change Patterns for Decision Model and Notation (DMN) Model Evolution

Information systems rely on decision knowledge during their execution. A recently introduced standard, the Decision Model and Notation (DMN), has been adopted in both industry and academia as a suitable method for modelling decision knowledge. However, this decision knowledge is not static and may undergo changes after system deployment. DMN change patterns have not yet been studied in the literature. This paper fills this gap by presenting an initial set of DMN change patterns. The patterns presented in this paper will not only facilitate the understanding of decision change management, but can also be capitalised on for, among other things, adapting decision management systems to be more flexible, consistency checking of decision models, and developing modelling tools that facilitate those changes.
