This book constitutes the refereed proceedings of the 8th International Conference on Agile Processes in Software Engineering and eXtreme Programming, XP 2007, held in Como, Italy in June 2007.

The 10 revised full papers and 16 revised short papers presented together with 4 poster papers, 18 experience papers, 2 research ideas and 3 panel summaries were carefully reviewed and selected from 45 submissions. The papers are organized in topical sections on managing agile processes, extending agile methodologies, teaching and introducing agile methodologies, methods and tools, empirical studies, and methodology issue.

Early research studies on open source software development often betrayed a mild surprise that loosely coordinated networks of volunteers could manage the design and implementation of highly complete software products. In the past few years, a wider research community has become increasingly aware of the tremendous contribution that open source development is making to the software industry, business and society in general. Software engineering researchers are exploring OSS specifically with respect to development tools and methodologies, while organizational scientists and economists are keen on understanding how open sources have brought large communities of people to help each other effectively.This book is an important step in the direction of a fuller understanding of the OSS phenomenon. It collects the proceedings of the Second International Conference on Open Software held in Como, Italy, from June 8th to June 10th, 2006. OSS 2006 was the foundation conference of the IFIP TC 2 WG 2.1 world interested in how OSS is produced, in its huge innovation potential in many different application fields and in OSS innovative business models. The 20 full papers of this volume were selected via a rigourous refereeing process among more than 100 submissions; 12 additional submissions, in view of their interest, were selected for publication in a more concise form.

The analysis of commonalities and differences between agile technology and open source software development is needed to understand how advancement approaches have evolved and whether they produce concrete benefits in terms of software quality and customer satisfaction. ""Agile Technologies in Open Source Development"" explores the overlap between open source and agile technologies, providing valuable strategies for advancement in software. This innovative publication provides a valuable resource to assist project managers, engineers, and developers interested in experimenting with new approaches in software expansion.
