Recent advances in modeling tools and techniques show the promise of significantly improving our ability to effectively apply systems engineering techniques to complex system-of-systems architectures. In this paper we describe our experience with the application of a model-based approach (based on SysML) to the capture and analysis of the end-to-end information systems supporting the first unmanned test flight of the Orion Multi-Purpose Crew Exploration Vehicle. The paper describes the EFT-1 mission, the approaches used to define the underlying models, how the models are related, and how viewpoints are used to address specific stakeholder concerns. The paper also provides a brief summary of the observed benefits of this approach as well as key lessons learned.
