More info
Modern-day projects require software and systems engineers to work together in realizing architectures of large and complex software-intensive systems. To date, the two have used their own tools and methods to deal with similar issues when it comes to the requirements, design, testing, maintenance, and evolution of these architectures.
Software and Systems Architecture in Action explores practices that can be helpful in the development of architectures of large-scale systems in which software is a major component. Examining the synergies that exist between the disciplines of software and systems engineering, it presents concepts, techniques, and methods for creating and documenting architectures.
The book describes an approach to architecture design that is driven from systemic quality attributes determined from both the business and technical goals of the system, rather than just its functional requirements. This architecture-centric design approach utilizes analytically derived patterns and tactics for quality attributes that inform the architect’s design choices and help shape the architecture of a given system.
The book includes coverage of techniques used to assess the impact of architecture-centric design on the structural complexity of a system. After reading the book, you will understand how to create architectures of systems and assess their ability to meet the business goals of your organization.
Ideal for anyone involved with large and complex software-intensive systems, the book details powerful methods for engaging the software and systems engineers on your team. The book is also suitable for use in undergraduate and graduate-level courses on software and systems architecture as it exposes students to the concepts and techniques used to create and manage architectures of software-intensive systems.

Biography
Raghvinder (Raghu) Sangwan is an associate professor of software engineering at Pennsylvania State University. His work involves design and development of software systems, their architecture, and automatic and semiautomatic approaches to assess their design and code quality. He has published several papers in these areas. Prior to joining the Pennsylvania State University, Raghu was a software architect at Siemens, where he worked on large-scale systems in the domains of health care, automation, transportation, and mining; many of these systems were developed by teams geographically distributed around the world. This experience resulted in his coauthoring the Global Software Development Handbook and co-organizing the first International Conference on Global Software Engineering (ICGSE 2006), sponsored by the Institute for Electrical and Electronics Engineers (IEEE). He also holds a visiting scientist appointment at the Software Engineering Institute at Carnegie Mellon University. He received his PhD in computer and information sciences from Temple University and is a senior member of IEEE and the Association for Computing Machinery (ACM).
