Digital Engineering (DE) strategy is defined by the Department of Defense and establishes five goals . One of the goals includes providing an enduring, authoritative source of truth, which moves the primary means of communication from documents to digital models and data. This enables access, management, analysis, use, and distribution of information from a common set of digital models and data, As a result, stakeholders have the current, authoritative, and consistent information for use over the lifecycle. The DE Model Based Systems Engineering (MBSE) Reference Architecture Framework (RAF) defines, at a minimum, the digital model authoritative source of truth, model structure, stakeholder needs, systems and subsystem context, process model elements, architecture types, views, viewpoints, and supporting methodologies and best practices. This framework is defined using the Systems Modeling Language, semantics, and constructs. The RAF structure is expressed to support DE transformation and help improve MBSE best practices.
