An improved system engineering model

Abstract

An enhanced system engineering model is described which includes features such as: clean separation of the roles of system acquisition, system development and component development through a layered approach; indefinite recursion of a single project into subprojects; distinct lifecycles for sub-projects; management of risk and commercial factors within the lifecycle. The authors believe that all of these features-and more-actually represent what the best engineers do (or at least what they attempt to do).
