The IT community has always struggled with questions concerning the value of an organizationa (TM)s investment in software and hardware. It is the goal of value-based software engineering (VBSE) to develop models and measures of value which are of use for managers, developers and users as they make tradeoff decisions between, for example, quality and cost or functionality and schedule a" such decisions must be economically feasible and comprehensible to the stakeholders with differing value perspectives. VBSE has its roots in work on software engineering economics, pioneered by Barry Boehm in the early 1980s. However, the emergence of a wider scope that defines VBSE is more recent. VBSE extends the merely technical ISO software engineering definition with elements not only from economics, but also from cognitive science, finance, management science, behavioural sciences, and decision sciences, giving rise to a truly multi-disciplinary framework.

Biffl and his co-editors invited leading researchers and structured their contributions into three parts, following an introduction into the area by Boehm himself. They first detail the foundations of VBSE, followed by a presentation of state-of-the-art methods and techniques. The third part demonstrates the benefits of VBSE through concrete examples and case studies.

This book deviates from the more anecdotal style of many management-oriented software engineering books and so appeals particularly to all readers who are interested in solid foundations for high-level aspects of software engineering decision making, i.e. to product or project managers driven by economics and to software engineering researchers and students.

This book contains both relevant real-world research, as well as reviews of different areas of interest in the software engineering literature, such as clone identification. The contents of the various sections will provide a better understanding of known problems and detailed treatment of advanced topics. Consequently, the book consolidates the work and findings from leading researchers in the software research community in key areas such as maintainability, architectural recovery, code analysis, software migration, and tool support.

It was 1999 when Extreme Programming Explained was ?rst published, making this year s event arguably the ?fth anniversary of the birth of the XP/Agile movement in software development. Our fourth conference re?ected the evolution and the learning that have occurred in these exciting ?ve years as agile practices have become part of the mainstream in software development. These pages are the proceedingsof XP Agile Universe 2004, held in beautiful Calgary, gateway to the Canadian Rockies, in Alberta, Canada. Evidentintheconferenceis thefactthatourlearningis still inits earlystages. While at times overlooked, adaptation has beena core principleof agile software development since the earliest literature on the subject. The conference and these proceedings re- force that principle. Although some organizations are able to practice agile methods in the near-pure form, most are not, re?ecting just how radically innovativethese methods areto thisday. Anyinnovationmustcoexistwithan existingenvironmentandagileso- ware development is no different. There are numerous challenges confronting IT and software development organizations today, with many solutions pitched by a cadre of advocates. Be it CMM, offshoring, outsourcing, security, or one of many other current topics in the industry, teams using or transitioning to Extreme Programming and other agile practices must integrate with the rest of the organization in order to succeed. The papers here offer some of the latest experiences that teams are having in those efforts. XP Agile Universe 2004consisted of workshops, tutorials, papers, panels, the Open Space session, the Educators Symposium, keynotes, educational games and industry presentations."

 This book constitutes the refereed proceedings of the Second International Conference on COTS-Based Software Systems, ICCBSS 2003, held in Ottawa, Canada in February 2003. The 24 revised full papers presented were carefully reviewed and selected from numerous submissions. The papers address all current issues on commcerial-off-the-shelf-systems, from the point of view of research and development as well as from the practitioner's application point of view.
