Development And Evolution Of Software Architectures For Product Families

This book contains the proceedings of a third workshop on the theme of Software Arc- tecture for Product Families. The first two workshops were organised by the ESPRIT project ARES, and were called “Development and Evolution of Software Architectures for Product Families”. Proceedings of the first workshop, held in November 1996, were only published electronically at: “http://www.dit.upm.es/~ares/”. Proceedings of the second workshop, held in February 1998, were published as Springer LNCS 1429. The ARES project was finished in February 1999. Several partners continued - operation in a larger consortium, ITEA project 99005, ESAPS. As such it is part of the European Eureka ! 2023 programme. The third workshop was organised as part of the ESAPS project. In order to make the theme of the workshop more generic we decided to rename it “International Workshop on Software Architectures for Product Families”. As with the earlier two workshops we managed to bring together people working in the so- ware architecture of product families and in software product-line engineering. Submitted papers were grouped in five sessions. Moreover, we introduced two s- sions, one on configuration management and one on evolution, because we felt that d- cussion was needed on these topics, but there were no submitted papers for these subjects. Finally, we introduced a surveys session, giving an overview of the present situation in Europe, focussed on ESAPS, and in the USA, focussed on the SEI Product Line Systems Program.

This book originates from a workshop organised by ESPRIT project 20 477, ARES in Las Palmas de Gran Canaria, Spain, February 1998. ARES is an acronym for Architectural Reasoning for Embedded Systems. Within this project we investigate techniques to deal with problems of software architecture of families of embedded systems. It is the second workshop organised by this project. Its predecessor was held in Las Navas de Marques, Spain, November 1996. The proceedings of the first workshop are only available in electronic format at "http://www.dit.upm.es/~ares/". The second workshop succeeded, even more than the first one, in gathering many of the most prominent people working in the area of software architecture for product families or product lines. This second workshop consisted of six sessions. The first session was meant to report the ARES results, according to the topics of the next five sessions. The remaining sessions dealt with different aspects of software architecture, focussed on applications for product families or product lines. Because there will be a separate book covering all ARES results, the first session is not included in this book. The workshop was chaired by Henk Obbink from Philips Research and Paul Clements from the Software Engineering Institute at Carnegie Mellon University. They prepared and presented an overall conclusion at the end of the workshop. This conclusion was used in the introduction to this book.

This book contains the proceedings of the Fourth International Workshop on Product Family Engineering, PFE-4, held in Bilbao, Spain, October 3–5, 2001. This workshop was the fourth in a series started in 1996, with the same s- ject, software product-family engineering. Proceedings of the second and third workshops have been published as LNCS 1429 and LNCS 1951. The workshops were organized within co-operation projects of European - dustry, the ?rst two by ARES (Esprit IV 20.477) 1995–1999. This project had three industrial and three academic partners, and focused on software archit- turesforproductfamilies.SomeofthepartnerscontinuedinITEAproject99005, ESAPS(1999–2001).ITEAisthesoftwaredevelopmentprogram(?!2023)within the European Eureka initiative. ITEA projects last for two years and ESAPS ́ was succeeded by CAFE (ITEA ip00004), which started in 2001 and will t- minate in 2003. This workshop was initially prepared within ESAPS and the ́ preparation continued in CAFE. Due to the attacks in the USA of September 11, several people were not able to ?y and therefore did not show up. However, we have included their submissions in these proceedings. The session chair presented these submissions, and their inputs were used during the discussions. It was planned that Henk Obbink be workshop chair, and Linda Northrop and Sergio Bandinelli be co-chairs. However, because of personal circumstances Henk Obbink was not able to leave home during the workshop. Moreover both co-chairs had already enough other duties. Therefore the chairing duties were taken over by the program chair, Frank van der Linden.

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.

Software product lines are emerging as a critical new paradigm for software development. Product lines are enabling organizations to achieve impressive time-to-market gains and cost reductions. With the increasing number of product lines and product-line researchers and practitioners, the time is right for a comprehensive examination of the issues surrounding the software product line approach. The Software Engineering Institute at Carnegie Mellon University is proud to sponsor the first conference on this important subject. This book comprises the proceedings of the First Software Product Line Conference (SPLC1), held August 28-31, 2000, in Denver, Colorado, USA. The twenty-seven papers of the conference technical program present research results and experience reports that cover all aspects of software product lines. Topics include business issues, enabling technologies, organizational issues, and life-cycle issues. Emphasis is placed on experiences in the development and fielding of product lines of complex systems, especially those that expose problems in the design, development, or evolution of software product lines. The book will be essential reading for researchers and practitioners alike.

The last decade has been one of great progress in the field of software architecture research and practice. Software architecture has emerged as an important subdis- pline of software engineering. A key aspect of the design of any software system is its architecture, i. e. the fundamental organization of a system embodied in its com- nents, their relationships to each other, and to the environment, and the principles guiding its design and evolution (as defined in the Recommended Practice for Arc- tectural Description of Software-Intensive Systems -- IEEE Std 1471-2000). - The First European Workshop on Software Architecture (EWSA 2004) provided an international forum for researchers and practitioners from academia and industry to discuss a wide range of topics in the area of software architecture, and to jointly f- mulate an agenda for future research in this field. EWSA 2004 distinguished among three types of papers: research papers (which describe authors’ novel research work), experience papers (which describe real-world experiences related to software architectures), and position papers (which present concise arguments about a topic of software architecture research or practice). The Program Committee selected 19 papers (9 research papers, 4 experience - pers, and 6 position papers) out of 48 submissions from 16 countries (Australia, B- zil, Canada, Chile, Finland, France, Germany, Italy, Japan, Korea, The Netherlands, Spain, Switzerland, Turkey, UK, USA). All submissions were reviewed by three members of the Program Committee.
