This updated edition of Software Reuse: Methods, Models, Costs is an essential guide to successful systematic, life cycle-based reuse. It explains in depth the fundamentals, economics, and metrics of reuse and shows how it can succeed, even in rapidly changing technology environments. This book emphasizes the type of complex systems that may evolve into "systems of systems."

Important material has been added on the changed state-of-the-art and state-of-the-practice of software reuse, on product-line architectures, on reuse economics, and maintenance of COTS-based systems.
