The Art of Systems Architecting

The Art of Systems Architecting, Fourth Edition provides structured heuristics to improve the least structured, most artlike elements of systems design. It offers unique techniques to bridge the difference between scientific engineering and qualitative design along with comprehensive methods for combining architectural design with digital engineering. This book illustrates how to go from modelbased systems architecture to modelbased systems engineering and includes case studies of good and bad architectural decisionmaking in major systems. Changes to this edition include materials on architecture processes, architecture description frameworks, and integration with MBSE (modelbased systems engineering) and digital engineering. The publication of the ANSI/IEEE 1471 and ISO/ IEC 42010 standards on architecture description has provided common vocabulary and organizing methods for documenting architectures. This edition provides a practical application of these standards in architecting and integrating their concepts with a simple process framework. The rise of MBSE and digital engineering tools is in the process of revolutionizing the development of complex systems. The emphasis has been on detailed design descriptions and powerful analysis methods (for example, digital twins). Architects can make effective use of these methods and tools as well, and this new edition provides an integrated set of heuristics and modeling methods to do so. There are This book can be used as a reference book for engineers and managers involved in creating new systems, people responsible for developing mandated architecture descriptions, software architects, system architects, and systems engineers, or as a textbook in graduate engineering courses. Exercises are interspersed throughout the text, with some designed for selftesting and understanding and others intended to provide opportunities for longterm study and further exploration of the subject.
