Systems engineering is unique in being characterised by its methods rather than its artefacts. Consequently, the scope of systems engineering is difficult to define. While some systems engineers contend that systems engineering is capable of addressing socio-technical problems, including climate change and terrorism, others argue that it is strictly a technical field. The paper presents the results of a discourse analysis of systems engineering textbooks, journal articles, and a qualitative questionnaire administered within the International Council on Systems Engineering United Kingdom Chapter and University College London Centre for Systems Engineering. The analysis finds three parallel accounts of systems engineering in the sampled community. These representations are of systems engineering as something new, as good engineering, and as a meta-methodology. The three distinct discourses of systems engineering diverge on its concept, origin, scope, role, training, epistemological positions, and worldview. The paper shows that claims for and against the wider applicability of systems engineering techniques to complex socio-technical problems not only chart alternative courses for the future of the field but are also grounded in particular constructions of its origins, practices and worldview. While this brings circumspection to the recent rise to prominence of systems engineering within broader engineering discussion and debate, it also provides an opportunity for reflexivity within the field as it responds to demands for integrated solutions to complex socio-technical problems.
