This course introduces concepts of business process modeling using the Business Process Model and Notation (BPMN) industry standard. Participants will learn the elements of process models and their precise meaning. Based on a thorough understanding of business process models, the last part of the course covers decision models using the Decision Model and Notation (DMN). Decision models complement process models by representing concrete, operational decisions, both with their structure and their decision logics. The course centers around concepts and language to describe and analyze business processes and decisions. It does not cover methods on how to model, improve, monitor or implement business processes. Still, a deep understanding of business processes and decisions is a useful basis for these activities.
