This book constitutes the refereed proceedings of the 8th International Conference on Software Reuse, ICSR-8, held in Madrid, Spain in July 2004. The 28 revised full papers presented were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on software variability: requirements; testing reusable software; feature modeling; aspect-oriented software development; component and service development; code level reuse; libraries, classification, and retrieval; model-based approaches; transformation and generation; and requirements.

Software reuse offers great cost-saving potential and this book spells out the methods and tools to realize these savings. Covering cost models for reuse, certification for reusable components and reuse-driven requirements engineering, this book helps demystify this area of software development.

As a result of the open-source movement there is now a great deal of reusable software available in the public domain. This offers significant functionality that commercial software vendors can use in their software projects. Open-source approaches to software development have illustrated that complex, mission critical software can be developed by distributed teams of developers sharing a common goal. Commercial software vendors have an opportunity to both learn from the op- source community as well as leverage that knowledge for the benefit of its commercial clients. Nonetheless, the open-source movement is a diverse collection of ideas, knowledge, techniques, and solutions. As a result, it is far from clear how these approaches should be applied to commercial software engineering. This paper has looked at many of the dimensions of the open-source movement, and provided an analysis of the different opportunities available to commercial software vendors. References and Notes 1. It can be argued that the open-source community has produced really only two essential 9 products -- Apache (undeniably the most popular web server) and Linux although both are essentially reincarnations of prior systems. Both are also somewhat products of their times: Apache filled a hole in the then emerging Web, at a time no platform vendor really knew how to step in, and Linux filled a hole in the fragmented Unix market, colored by the community s general anger against Microsoft. 2.Evans Marketing Services, Linux Developers Survey, Volume 1, March 2000.

This book documents methods for quantifying the benefits of software reuse so that developers can accurately judge whether the benefits outweigh the disadvantages. It explains how to apply reuse metrics, reuse economic models, and reuse Return-On-Investment (ROI) models in diverse organizations and many different programming languages.

McClure takes software reuse beyond "good intentions", by presenting specific reuse techniques that have repeatedly helped companies lower costs and improve quality.

The book provides a clear understanding of what software reuse is, where the problems are, what benefits to expect, the activities, and its different forms. The reader is also given an overview of what sofware components are, different kinds of components and compositions, a taxonomy thereof, and examples of successful component reuse. An introduction to software engineering and software process models is also provided.
