BPMN (Business Process Model and Notation) is the new standard for business process modeling. Within a short period, it has gained widespread adoption in practice. All important modeling tools support BPMN diagramming. It is possible to create business-oriented diagrams, but also technical models for process execution in workflow or business process management systems (BPMS). The new BPMN version 2.0 contains several additional elements and new types of diagrams, especially for improved modeling of processes that span several independent organizations. This book provides a stepwise introduction to BPMN, using many examples close to practice. Starting with the basic elements for modeling sequence flow, all BPMN 2.0 diagrams are presented and discussed in detail. You will gain a profound understanding of the complete notation, and you will be able to use the different language elements correctly.
