4 Preface Unbelievable, we have reached the seventh edition of the XP2k+n conference! We started at the outset of the new millennium, and we are still proving that agile processes were neither a millennium bug nor a YAF (yet another fad). In its first editions, this conference was a get-together of a few pioneers who debated about how to make agile processes and methods accepted by the mainstream researchers and practitioners in software engineering. Now agile approach to software development has been fully accepted by the software engineering community and this event has become the major forum for understanding better the implications of agility in software development and proposing extensions to the mainstream approaches. These two aspects were fully reflected in this year s conference. They were reflected in the keynote speeches, which covered the background work done starting as early as the early eighties by Barry Boehm, definition of the field by Kent Beck, a successful industrial application in a success story by Sean Hanly, the perspective and the future of agile methods in large corporations by Jack Järkvik, and even some insightful views from a philosopher, Pekka Himanen. They were reflected in the technical sessions and in their papers, spanning from the definition and the consolidation of the theory (with specific attention to topics like pair programming, quality, experimental data) and reaching controversial areas, such as distributed agile development and new practices involving usability and security issues The papers went through a rigorous reviewing process. Each paper was reviewed by at least three Program Committee members. Of 59 papers submitted, only 16 were accepted as full papers. Panels, workshops, activities, and tutorials enriched the conference, introducing a wide variety of topics and of discussion techniques. But the highest value of any conference, and especially of a XP2k+n conferences is in the people who attend it, this is why we think that this seventh edition of the conference was unique: because of its wide variety of ingenious, curious, dynamic, and nice participants. We thank all who contributed to the XP 2006 event. The authors, sponsors, the chairs, the reviewers, and all the volunteers: without their help, this event would not have been possible.
