This is the goal of value-based software engineering (VBSE) to develop the model and measure of value used for managers, developers and users as they make tradeoff decisions between, for example, quality and cost or functionality and schedule? VBSE rooted in work on software engineering economics, pioneered by Barry Boehm in the early 1980s. VBSE expand the ISO software engineering definition with only technical elements not only of economics, but also from cognitive science finance, management science, behavioral science, and decision sciences, giving rise to a framework for a truly multi-disciplinary. Biffl and his co-editors invited leading researchers and structured their contributions into three parts, following the introduction into the area by Boehm himself. The third section shows the benefits of VBSE through real world examples and case studies. This book deviates from the more anecdotal style of many book-oriented management software engineering and so appealing particularly to all readers who are interested in a strong foundation for high-level aspects of software engineering decision-making, namely
