With SPLC 2005 we celebrated the formation of a new conference series, the International Software Product Line Conference (SPLC) which results from the “uni?cation” of the former series of three SPLC (Software Product Line) Con- rences launched in 2000 in the USA, and the former series of ?ve PFE (Product Family Engineering) Workshops started in 1996 in Europe. SPLC is nowthe premier forum for the growing community of software p- duct line practitioners, researchers, and educators. SPLC o?ers a unique - portunity to present and discuss the most recent experiences, ideas, innovations, trends,andconcernsintheareaofsoftwareproductlineengineering andtobuild aninternationalnetworkofproductlinechampions.AninternationalSPLCSt- ring Committee has been established and it is the wish of this committee that from 2005 on, the SPLC conference will be held yearly in Europe, America, or Asia. The technical program of SPLC 2005 included. – two keynotes from David Weiss (Avaya, USA) and Jan Bosch (Nokia, F- land), both leading experts with academic and industrial insights; – 17 full and 3 short research papers organized around the following themes: feature modeling, re-engineering, strategies, validation, scoping and arc- tecture, and product derivation; – eight experience reports describing commercial application of product line practices; – two panels focused on special topics in product line practice and product line research; – tool demonstrations; – aHallofFamesessionthatcontinuedtheSPLCtraditioninaslightlyrevised format. In addition, the technical program was preceded by a tutorial and workshop day that included ten half-day tutorials presented by well-recognized experts and ?ve workshops on speci?c areas of product line research.
