Software product line engineering has proven to be the methodology for developing a diversity of software products and software intensive systems at lower costs, in shorter time, and with higher quality. In this book, Pohl and his co-authors present a framework for software product line engineering which they have developed based on their academic as well as industrial experience gained in projects over the last eight years. They do not only detail the technical aspect of the development, but also an integrated view of the business, organisation and process aspects are given. In addition, they explicitly point out the key differences of software product line engineering compared to traditional single software system development, as the need for two distinct development processes for domain and application engineering respectively, or the need to define and manage variability.

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.

While standardization has empowered the software industry to substantially scale software development and to provide affordable software to a broad market, it often does not address smaller market segments, nor the needs and wishes of individual customers. Software product lines reconcile mass production and standardization with mass customization in software engineering. Ideally, based on a set of reusable parts, a software manufacturer can generate a software product based on the requirements of its customer. The concept of features is central to achieving this level of automation, because features bridge the gap between the requirements the customer has and the functionality a product provides. Thus features are a central concept in all phases of product-line development. The authors take a developer’s viewpoint, focus on the development, maintenance, and implementation of product-line variability, and especially concentrate on automated product derivation based on a user’s feature selection. The book consists of three parts. Part I provides a general introduction to feature-oriented software product lines, describing the product-line approach and introducing the product-line development process with its two elements of domain and application engineering. The pivotal part II covers a wide variety of implementation techniques including design patterns, frameworks, components, feature-oriented programming, and aspect-oriented programming, as well as tool-based approaches including preprocessors, build systems, version-control systems, and virtual separation of concerns. Finally, part III is devoted to advanced topics related to feature-oriented product lines like refactoring, feature interaction, and analysis tools specific to product lines. In addition, an appendix lists various helpful tools for software product-line development, along with a description of how they relate to the topics covered in this book. To tie the book together, the authors use two running examples that are well documented in the product-line literature: data management for embedded systems, and variations of graph data structures. They start every chapter by explicitly stating the respective learning goals and finish it with a set of exercises; additional teaching material is also available online. All these features make the book ideally suited for teaching – both for academic classes and for professionals interested in self-study.

This book covers research into the most important practices in product line organization. Contributors offer experience-based knowledge on the domain and application engineering, the modeling and management of variability, and the design and use of tools to support the management of product line-related knowledge.

illustrates a process that has been successfully applied to reduce costs for organizations that develop large programming systems. With the help of this book, many more can learn how to exploit the idea of program families and bring about a substantial improvement in the state of practice in the software industry. --David Lorge Parnas Many organizations have mastered the practice of software development, yet few have become truly efficient at software production. With the adoption of an efficient, systematic software production method, organizations can gain significant competitive advantages, including reduced time to market, better schedule predictability, more reliable code, and decreased costs. Software Product-Line Engineering provides the actionable information and proven tactics necessary to effect organizational change and make your future software projects more successful. The authors outline a systematic method for rapid software production through the FAST (Family-Oriented Abstraction, Specification, and Translation) process, a revolutionary commercial product developed at AT&T that continues to evolve at Lucent Technologies. FAST uses practical domain engineering to dec

The Pernambuco School on Software Engineering (PSSE) 2007 was the second in a series of events devoted to the study of advanced computer science and to the promotion of international scienti?c collaboration. The main theme in 2007 was testing. Testing is nowadays a key activity for assuring software quality. The summer school and its proceedings were intended to give a detailed tutorial introduction to the scienti?c basis of this activity and its state of the art. Theseproceedingsrecordthecontributionsfromtheinvitedlecturers.Eachof thechaptersistheresultofathoroughrevisionoftheinitialnotesprovidedtothe participants of the school. The revision was inspired by the synergy generated by the opportunity for the lecturers to present and discuss their work among themselves and with the school’s attendees. The editors have tried to produce a coherent view of the topic by harmonizing these contributions, smoothing out di?erences in notation and approach, and providing links between the lectures. We apologize to the authors for any errors introduced by our extensive editing. Although the chapters are linked in severalways, each one is su?ciently se- contained to be read in isolation. Nevertheless, Chap. 1 should be read ?rst by those interested in an introduction to testing. Chapter 1 introduces the terminology adopted in this book. It also provides an overview of the testing process, and of the types (functional, structural, and so on)anddimensions(unit,integration,andsoon)ofthetestingactivity.Themain strategies employed in the central activity of test selection are also discussed. Most of the material presented in this introductory chapter is addressedin more depth in the following chapters.
