In the ever-changing world of software development, organizations are gradually realizing the need for an explicit software architecture for their systems. And software engineers are potentially faced with the challenge of developing multiple, inter-related systems whilst pressured by financial and lead-time constraints. It is thus essential to establish a well-defined design method in order to build high-quality, reliable, and easily maintainable individual or families of systems - the question is how to approach this? This book provides an achievable answer. The author proposes a method for designing software architectures, and product line architectures, which is based on his experience in industry and research, The first part of the book introduces the design method, examining its three key phases - functionality-based architecture design, architecture assessment and architecture transformation - in detail. The second half of the book explores the concept of software product lines, incorporating elements of architectural design, component-based software engineering and reuse. It takes you through the process of designing, developing and evolving a product-line approach, including the development of software architecture and components for the family, instantiation of family members and evolution of assets. It also examines the pros and cons of a number of organizational models that can be applied when putting a software product line approach in to practice. If you are a software architect or engineer involved in designing software systems architectures, this book will give you the resources you need for success. · features real-life case studies covering control and real-time systems, networking, and telecommunications industry examples to illustrate how the method and processes work in practice · provides a systematic approach that employs both qualitative and quantitative techniques for assessments · contains key chapters on approaches to component development, and use of object-oriented frameworks as components in software product lines · includes sections that can be read as stand-alone, depending on your level of knowledge and experience and your specific area of interest.

Industrial experiences -- Designing software architectures that maximize reuse and flexibility.-- Leveraging software architectures across product lines and families.-- Includes detailed, real-world case studies.Sophisticated development organizations worldwide are discovering the advantages of software architectures in building systems that deliver higher quality, lower development and maintenance costs, and shorter time to market. In this book, one of the field's leading experts addresses the two most important factors in making software architectures work: effective design, and leveraging architectures across product lines. Jan Bosch begins by outlining the rationale for software architectures, and reviewing the limits of traditional approaches to software reuse. Next, Bosch introduces a comprehensive approach to software architecture design that includes explicit quality goals, is carefully optimized up front, and still accounts for the inevitability of change. In Part II, Bosch presents today's best practices for defining architectures that can be reused across entire "lines" or "families" of software. Bosch covers each phase of the software product line lifecycle, including development, usage, and evolution of software assets, showing how to manage interdependencies, and cope with new requirements that were not part of the original design. The book includes several running case studies from real companies that have achieved competitive advantage through software architecture.
