This book and the certification program, OMG Certified Expert in Business Process Management 2, discuss basic knowledge and the concepts of business process management and business process modeling. These are stable and long-term topics. Concrete technologies tend to be instable, and our book contains such a component: the Business Process Model and Notation, or BPMN for short.

Five years have passed since the first edition. By then it was already clear that there would be a new version of BPMN. But because changes are always looming on the horizon, this did not prevent OMG from starting the OCEB certification program with the old BPMN in 2010. Nor did it discourage us to write a book on this topic. In 2011, BPMN 2.0 replaced BPMN 1.2.

For almost 2 years, a group of experts has been working on an update of the OCEB certification program, particularly with regard to the update from BPMN1 to BPMN2. Our author, Tim Weilkiens, is a member of this group of experts and contributes to the certification topics and questions. We updated our book in line with the update of the OCEB certification program. It prepares for the initial certification of OCEB2 and imparts basic information on business process management and business process modeling, using BPMN. The book is not only interesting for test preparation, but it also constitutes a compact reference on these topics.

Feedback that we received on the first edition was considered in this second edition. We hope you enjoy reading this book and that it imparts useful information. We look forward to receiving your feedback!
