Jan Vanthienen is full professor of business & information systems engineering at KU Leuven (Belgium), Department of Decision Sciences and Information Management, Information Systems Group. He is an active researcher in the area of intelligent business systems (rules, decisions, processes, analytics).

Jan is actively involved in the Decision Modeling & Notation standard (DMN) at OMG (Object Management Group). This standard is designed to complement the Business Process Modeling & Notation (BPMN) standard, in order to integrate and distinguish business processes and business decisions. He is also member of the IEEE task force on process mining, and co-author of the Business Process Mining Manifesto.
He has published numerous papers in reviewed international journals and conference proceedings. He received an IBM Faculty Award in 2011 on smart decisions, and the Belgian Francqui Chair 2009 at FUNDP. He is co-founder and president-elect of the Benelux Association for Information Systems (BENAIS). Jan is a founding member of the Leuven Institute for Research in Information Systems (LIRIS), and is/was chairholder of the bpost bank Research Chair on Actionable Customer Analytics, the Colruyt Research Chair on Smart Marketing Analytics, the PricewaterhouseCoopers Chair on E-Business and the Microsoft Research Chair on Intelligent Environments.


Business processes and business process models incorporate lots of decisions. Business decisions are important, but are often hidden in process flows or activities. It is not considered good practice to model the detailed decision paths in the business process model, because hardcoding decision flows in processes leads to complex and inflexible process models. Separating decisions from the process simplifies the process model (separation of concerns).

In analogy with the Business Process Modeling & Notation Standard (BPMN), a Decision Model & Notation standard (DMN) is developed by OMG. Decision modeling describes business decisions to be made, with their interrelationships and requirements, together with the detailed decision logic used to make the decision. One of the common forms of decision modelling is a structure of decision tables, describing the premises and resulting outcomes of a specific decision situation. This tutorial introduces DMN and describes the relations between business decisions, decision tables, and business processes.
