This book constitutes the thoroughly refereed post-proceedings of the 5th International Workshop on Product-Family Engineering, PFE 2003, held in Siena, Italy in November 2003.
The 36 revised full papers presented together with an introductory overview and 3 keynote presentations were carefully selected during two rounds of reviewing and improvement. The papers are organized in topical sections on variation mechanisms, requirements analysis and management, product derivation, transition to family development, industrial experience, evolution, and decision and derivation.
