This book describes the foundation processes and analytical practices for identifying, analyzing, measuring, and managing risk in traditional systems, systems-of-systems, and enterprise systems. It uses numerous examples and chapter exercises to illustrate how principles are applied to actual engineering systems projects. The author presents a new way, in the form of a supplier–provider framework, to model and measure risk in the engineering of enterprise systems being developed by capabilities-based approaches. He also explores research ideas for the development of advanced risk analysis and management protocols and discusses success factors for managing risk in the engineering of systems.
