Preface

Reference models for business processes have been a successful means for designing, redesigning, tailoring, and implementing business processes. Still there is no common understanding of reference models for business processes: • What is a reference model? • What makes them different from a business process model? • What should be covered by a reference model? • What is their purpose and how should they be used? • How should they be designed and presented? The workshop brings together people from different application areas, using different notations and formalisms, in order to present and discuss their point of view. The workshop should help • to share experiences with the use of reference models, • to better understand the purpose and the role of reference models, • to identify the aspects that should be covered by reference models, • to discuss notations and meta models for reference models, and, eventually, • to come up with a technology to efficiently design and to use reference models. We are happy that the workshop on Business Process Reference Models was accepted as a satellite event of BPM 2005, and we would like to thank the local organizers for their work and support in organizing this event. Moreover, we would like to thank the Program Committee and all referees for helping select and improve the contributions to this workshop. Many thanks also to all authors for their contributions
