Daniel Colomer, Xavier Franch , p. 178-180 Preface The iStar workshop series is dedicated to the discussion of concepts, methods, techniques, tools, and applications associated with i* and related frameworks and approaches. Following successful workshops in Trento, Italy (2001), London, England (2005), Recife, Brazil (2008), and Hammamet, Tunisia (2010), the 5th International i* Workshop is being held back again in Trento. As with previous editions, the objective of the workshop is to provide a unique opportunity for exchanging ideas, comparing notes, and forging new collaborations. This year, the workshop is co-located with the 19 th IEEE International Requirements Engineering Conference (RE 2011), benefiting from the common interests shared by the workshop and the conference. As with past editions, we have tried to keep the format small and informal so as to maximizing interaction. However, the increasing number of submissions and presented papers have forced for the first time in the workshop to organize some parallel sessions. We preferred to adopt this option, rather than to reduce the time allocated to papers or be more restrictive in the acceptance process. We have included in the wrap-up session a 5- minute summary of each parallel session given by the session chairs. Also in terms of format, the 30 minutes allocated to each paper have been split equally into presentation and discussion. Concerning the review process, each of the 29 submitted papers went through a thorough review process with three reviews from a programme committee, providing useful feedback for authors. Revised versions of the 25 accepted papers are included in these proceedings. We thank authors and reviewers for their valuable contributions. The program was completed with a keynote given by Prof. Munindar P. Singh entitled “Governing Sociotechnical Systems” and a tools fair in which 10 tools were presented in a plenary session - the first such event in the workshop series. Last but not least, we want to deeply thank the organizers of the RE conference for their great support. We look forward to lively conversations and debates with old and new friends at the workshop, in the wonderful surroundings of Trento, Italy!
