CAiSE 2000 was the 12th in the series of International Conferences on Advanced Information Systems Engineering. In the year 2000 the conference returned to Stockholm where it was organized the very first time. Since that year, 1989, the CAiSE conferences have developed into an important forum for the presentation and exchange of research results and practical experiences within the field of Information Systems Engineering. The objective of the CAiSE conference series is to bring together researchers and practitioners in the field of information systems engineering to meet annually in order to discuss evolving research issues and applications in this field. The CAiSE conference series also aims to provide an opportunity for young scientists to establish relationships with senior scientists in their areas of interest. Stockholm is an important center of research and development for some of the leading IT and communications companies in Europe and indeed, in the world. In tune with this environment, a major theme of CAiSE 2000 was "information systems and services in a digitized world". This theme reflects the vast improvements in communication technology, including the increasing use of Internet and WWW, that has taken place over the last years, and that has led to better communication and easier information access in general. In addition, this development has initiated changes in the way organizations cooperate and trade.
