The U.S. Department of Defense (DoD) Digital Engineering Strategy [1] introduced digital engineering as the catalyst to transform the design and delivery of complex systems. DoD defines digital engineering as “an integrated digital approach that uses authoritative sources of system data and models as a continuum across disciplines to support lifecycle activities from concept through disposal” [1]. The Office of the Under Secretary of Defense for Research and Engineering [OUSD(R&E)] and the Armed Services are currently rolling out initiatives to implement digital engineering. This paper provides an overview of the digital engineering strategy and implementation efforts that will advance the state of practice.
