George Friedman (Friedman, 2006) called for the development of a grand unified theory of systems engineering (GUTSE) echoing (Hill and Warfield, 1972) who wrote “development of a theory of systems engineering that will be broadly accepted is much to be desired.” Taking up the spirit of the challenge, this paper applies systems thinking to systems engineering to propose a framework that can serve as a vital element in formalizing the discipline of systems engineering and potentially as a platform for developing such a theory.
This paper focuses on what systems engineers do, and builds on past research and success. Documenting research using an object‐oriented approach in a creative and innovative manner it discusses the evolution of a proposed framework for systems engineering that meets or shows promise of meeting the following four requirements (Kasser, 2006):
The framework shall provide an understanding of why systems engineers can't agree on their roles and activities.
The framework shall provide an understanding of the reasons for the overlap between systems engineering and management.
The framework shall provide a way to cope with complexity.
The framework shall enable the lowering of the cost of doing work by at least an order of magnitude.
The framework is based on a combination of the Hitchins' five‐layer representation of systems engineering (Hitchins, 2000) extended by Kasser and Massie over the systems lifecycle phases (Kasser and Massie, 2001) coupled with Shenhar and Bonen's taxonomy of systems based on technological uncertainty (risk) (Shenhar and Bonen, 1997).
