Software product lines represent perhaps the most exciting paradigm shift in software development since the advent of high-level programming languages. Nowhere else in software engineering have we seen such breathtaking improvements in cost, quality, time to market, and developer productivity, often registering in the order-of-magnitude range. Here, the authors combine academic research results with real-world industrial experiences, thus presenting a broad view on product line engineering so that both managers and technical specialists will benefit from exposure to this work. They capture the wealth of knowledge that eight companies have gathered during the introduction of the software product line engineering approach in their daily practice.

Frank van der Linden has worked at Philips Medical Systems in The Netherlands since 1999 and been involved with software product lines since then. He was program chair of a series of five workshops on product line engineering, is a member of the steering committee of the SPLC conferences, and co-authored 'Software Product Line Engineering' published by Springer in 2005.

Klaus Schmid is professor for software engineering at the University of Hildesheim, Germany. Previously, he was department head for requirements engineering and usability engineering at the Fraunhofer Institute for Experimental Software Engineering (IESE) in Kaiserslautern, Germany. He has been involved in numerous research and industrial projects in product line engineering.

Ee co Rommes worked at Philips Research in the area of software architecture for medical systems from 2001 to 2006. During that time he was involved in several research projects and he has published on software product lines and related topics.
