Redesigning processes for decision-awareness: Strategies for integrated modelling

The integration of decisions into processes has seen a surging interest in literature since the introduction of the Decision Model and Notation (DMN) by the Object Management Group (OMG) in 2015. The DMN standard has successfully been adopted in both industry and academia, as it provides a suitable approach towards filling the void of decision representation in the field of Business Process Management (BPM). Although a number of approaches exist in literature on how to build DMN models, or on how to extract DMN models from process models, no clear modelling strategies have been presented to introduce decision-awareness into existing processes. This paper discusses strategies for integrated process and decision modelling, as well as their implications for process redesign in order to render processes decision-aware. The modelling strategies are inferred from literature, as existing approaches are categorised, and their advantages and disadvantages are elaborated upon.
