Digital engineering is an integrated digital approach that uses authoritative sources of systems data and models as a continuum across disciplines to support lifecycle activities from concept through disposal. With digital engineering, models are developed for everything, not just for software, but for all components of a system of systems, hardware and software. The models and associated data are stored in a singular repository of knowledge and are the single source that is used by all contractors and everyone working on the project. In this SEI Podcast, David Shepard, a researcher with the Carnegie Mellon University Software Engineering Institute, discusses digital engineering and its relationship with DevSecOps.
