Orion flight test 1 architecture — Observed benefits of a model based engineering approach

This paper details how a NASA-led team is using a model-based systems engineering approach to capture, analyze and communicate the end-to-end information system architecture supporting the first unmanned orbital flight of the Orion Multi-Purpose Crew Vehicle. Along with a brief overview of the approach and its products, the paper focuses on the observed program management-level benefits, challenges, and lessons learned; all of which may be applied to improve system engineering tasks for characteristically similarly challenges.
