Complex systems continue to confound the capabilities of systems engineers to deal and navigate a new generation of problems. Thus, there is an emerging need to develop a cadre of effective systems engineers capable of efficiently addressing complex systems problems. This paper introduces a new system engineering instrument that assesses the performance of systems engineers. The instrument is based on the set of performance indicators examining six fundamental system engineering attributes. This instrument would provide a baseline to understand the current state of the systems engineering skills for a systems engineer and indicate developmental areas to enhance those skills. Following a brief introduction, this paper is structured to explore four primary areas. First, we examine why there is a need to develop effective systems engineers. Second, we proposed a novel tool that could assess the state of systems engineering skill and support purposeful development of skills. Third, we present an examination of the individual performance of induvial systems engineers. Fourth, a discussion is presented on the utility and implications for the proposed instrument.
