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.

Nichts ist älter als der Erfolg von gestern. Im internationalen Wettbewerb nimmt der Druck für Start-ups und etablierte Unternehmen zu: innovative Produkte und Dienstleistungen müssen in immer kürzeren Zyklen entwickelt und geliefert werden. Personalmangel, hohe Unternehmenssteuern und lange Antragswege sind nur einige der Innovationshemmnisse, die den Abstand deutscher Unternehmen zur Weltspitze vergrößern. Aktuelle weltpolitische Ereignisse offenbaren eine starke Abhängigkeit Deutschlands von Dritten, insbesondere bei Energie und Nahrung, aber auch bei der Digitalisierung. In allen Bereichen muss eine unternehmerische Trendwende eingeleitet werden. Dazu soll dieses Buch Impulse geben. Viele praxiserprobte Ideen und Anregungen aus der aktuellen Innovationsszene für die Bereiche Organisation, Vertrieb, Führung und Personalwesen werden vorgestellt - zumeist von Führungskräften, die wissen, "wie es geht". Ein Mix aus akademischen und praktischen Ansätzen zeigt den Lesern, wie diese erfahrenen Führungskräfte in ihren Betrieben mit Krisen, Herausforderungen und Innovationsprojekten umgegangen sind. Sie erhalten "lessons learned", die sie bei ihren eigenen Ansätzen für eine innovative Unternehmensführung unterstützen können.
