The open source phenomenon has attracted an increased interest among commercial firms and governments. It is becoming one of the most influential paradigm shifts not only in software development but in social and economic value creation as well. While software development is perhaps the most prominent example of open source, its principles have now been applied across a wide range of product classes, industries and even scientific disciplines. Decision makers at different levels and in a variety of fields need to improve their understanding of the factors that contribute to the Open Source Software (OSS) effectiveness: approaches, tools, social designs, reward structures and metrics. Successful OSS Project Design and Implementation provides a state-of-the-art analysis of OSS design principles, their emergence and success and how they are extending well beyond the domain of software.
