This volume contains the proceedings of the 3rd International Conference on Business Process Management (BPM 2005), organized by LORIA in Nancy, France, September 5–8, 2005. This year, BPM included several innovations with respect to previous e- tions, most notably the addition of an industrial program and of co-located workshops. This was the logical result of the significant (and still growing) - dustrial interest in the area and of the broadening of the research communities working on BPM topics. The interest in business process management (and in the BPM conference) was demonstrated by the quantity and quality of the paper submissions. We received over 176 contributions from 31 countries, accepting 25 of them as full papers (20 research papers and 5 industrial papers) while 17 contributions were accepted as short papers. In addition to the regular, industry, and short pres- tations invited lectures weregiven by Frank Leymannand Gustavo Alonso.This combination of research papers, industrial papers, keynotes, and workshops, all of very high quality, has shown that BPM has become a mature conference and the main venue for researchers and practitioners in this area. We would like to thank the members of the Program Committee and the reviewers for their efforts in selecting the papers. They helped us compile an excellent scientific program. For the difficult task of selecting the 25 best papers (14% acceptance rate) and 17 short papers each paper was reviewed by at least three reviewers (except some out-of-scope papers).
