The conference organizers selected 89 papers for publication and full, thirty-minute oral presentation (completed work). In addition, 145 papers, reflecting work in progress or position papers, were accepted for short presentation and another 138 papers were accepted for poster presentation. These numbers, leading to a “full-paper” acceptance ■ The Sixth International Conference on Enterprise Information Systems (ICEIS) was held in Porto, Portugal; previous venues were in Spain, France, and the United Kingdom. Since its inception in 1999, ICEIS has grown steadily, and is now one of the largest international conferences in the area of information systems. In 2004, more than 600 papers were submitted to the conference and its ten satellite workshops. One of the interesting features of this conference is the high number of invited speakers.
