The evolution of systems engineering as a transdiscipline

Abstract Systems engineering's evolutionary trajectory has been far from linear, and its future direction is uncertain. We present an assessment and vision of how SE might evolve to enduringly be impactful and relevant, despite growing complexity and radical technological change. We discuss how SE started out focused on achieving technical objectives, then drifted towards a more process and methodology focus, and is now responding to calls to return to its roots under the banner of “attaining elegant solutions to complex problems.” We discuss how SE has always been a transdiscipline, although it was not always so recognized, and how SE is now increasingly recognizing and valuing its transdisciplinary nature. We present our view that the future of SE as an impactful and relevant engineering discipline lies in the strengthening of its transdisciplinarity and an increased focus on attaining elegant solutions to complex problems. We present a framework for understanding the nature of SE and the way in which it evolves in terms of its principles, methods and purposes. We show that SE is informed by, and informs many disciplines and social institutions in a dynamic ecology of discovery, achievement and vision. Lastly, we discuss the value of this framework, and show how it can serve as a basis for developing a common understanding of the value and potential of SE, and support institutions such as INCOSE as they engage in the wider social agenda of building a better and more sustainable world.
