Using SysML v2 to Define a Digital Engineering Methodology

A Methodology is a comprehensive set of technical guidance providing model patterns and work instructions to engineer a system throughout its life cycle in an efficient and consistent manner.Digital Engineering is “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” (US DoD, https://man.fas.org/eprint/digeng-2018.pdf).A Digital Engineering (DE) methodology is expected to provide a comprehensive, data driven approach to system development, utilizing digital models and simulation across the entire lifecycle. Methodology objectives are to enable faster, more informed decision-making, to improve collaboration, to reduce risks, and to obtain higher quality end-products.Model-based Systems Engineering (MBSE) is a discipline within digital engineering that relies on creating digital models to manage the entire system lifecycle.
