Proceedings of CAiSE 2009 Forum Preface Since its inception in 1978, the International Conferences on Advanced Information System Engineering has been recognized as the premier conference in the field. CAiSE 2009, held 8-12 June 2009, in Amsterdam, the Netherlands, was the 21st in the series. The special theme for this edition was "Information Systems for Business Innovation: The Next Wave." Due to the widespread use of the web, businesses innovate their propositions to customers and come up with new ICT- enabled services. Such innovation requires understanding of the business and of technology in an integrated way. Multi-disciplinary research areas such as Service Science, Networked Enterprises, and Social Networking are paying attention to ICT and business innovation. In the tradition of the CAiSE conferences, the CAiSE Forum offers opportunities for interactive presentation and open discussion of ongoing research. The CAiSE Forum 2009 included a collection of 14 research contributions selected by the CAiSE 2009 program committee. The contributions were revised by the authors for submission to the Forum, and presented as posters at the exhibition session during the conference. As editors of this volume, we would like to express our gratitude to the program board, the program committee and external reviewers for their efforts in providing very thorough evaluations of the submitted CAiSE papers. We also would like to thank Richard van de Stadt for his very effective support during the paper evaluation and proceedings preparation. Finally, many thanks to the Free University of Amsterdam, CTIT, SIKS, NWO, Capgemini, Jacquard, the Network Institute, the University of Twente, and Zuidas for their sponsorship.
