Systems Engineering consists of two significant disciplines: the technical knowledge domain in which the systems engineer operates, and systems engineering management. This book focuses on both with equal treatment. The main feature of the book is blending traditional systems engineering with application to the Department of Defense (DoD) Adaptive Acquisition Pathway, a recent and major change to DoDs acquisition of new systems. Holistically, the book treats the technical systems engineering processes , the project processes or control processes, and the acquisition processes as integral parts. In addition, the organizational processes that enable systems engineering--the enterprise processes--as well as the as well as agreement process through which user/stakeholder requirements are established. are considered. Together, these provides a structure for solving system design problems that produce validated capabilities.
