Overcoming Inadequacies in Process Modelling: The Need for Decisioning Be a First-Class Citizen

Process modelling is a way of analysing, describing and enacting the behaviour of processes. A behaviour that process modelling fails to address is that of decision making. Despite the importance of organisational decisions, process modelling languages do not provide any semantics for expressing decision-making aspects such as the identification of alternatives and the handling of uncertainty. This paper proposes an approach, drawing on ideas from decision analysis, to enhance process modelling in the support of decision making. A decision-analysis process model is used to demonstrate the applicability of the approach.
