Systems Engineering and Architecture
Digital Engineering, Modeling & Simulation
DEM&S is responsible for advancing activities involving systems engineering, digital engineering (DE), and modeling and simulation (M&S). The team develops governing policies, and advancing enhancing workforce competency, as codified in the DoD Directive 5137.02, "Under Secretary of Defense for Research and Engineering."
Digital engineering must be the normal way to design and develop weapon systems. Together, OE and M&S are the means for the DoD to achieve the National Defense Strategy's desired end state of delivering rapid capabilities to the warfighter.
DE and M&S optimize processes to automate the design, development, and integration of systems through collaborative environments such as a Digital Engineering Ecosystem (DEE). When models mature to the point of replicating the system, developers can design and integrate more frequently, while testing earlier, more often, and more thoroughly than with the traditional DoD acquisition process. By using DE and M&S practices, designers can detect system defects earlier in the development process, saving time and money and improving overall quality.
Digital Engineering
Digital engineering uses authoritative sources of system data and models throughout the development and life of a system. Digital engineering harnesses computational technology, modeling, analytics, and data sciences to update traditional systems engineering practices. In the face of increasing global challenges and dynamic threat environments, digital engineering is a necessary practice to support acquisition.
Modeling and Simulation
The use of models and simulations in engineering is well recognized. Simulation technology is an essential tool for engineers in all application domains. A digital model represents an actual or conceptual system that involves physics, mathematics, or logical expressions. A simulation is a method for implementing a model over time. Together models and simulations allow the Department to vet potential requirements prior to the Request for Proposal release, assess engineering change orders or program upgrades, etc. M&S can be used to assess and optimize resource usage, examine process changes, support supply-chain management routing and inventory quantities, business decisions, etc.
Digital Engineering Strategy
The Digital Engineering Strategy outlines the Department’s five strategic goals for the digital engineering initiative. The goals promote the use of digital representations of systems and components and the use of digital artifacts as a technical means of communication across a diverse set of stakeholders. The strategy addresses a range of disciplines involved in the acquisition and procurement of national defense systems, and it encourages innovation in the way we build, test, field, and sustain our national defense systems and how we train and shape the workforce to use these practices.
DoD Instruction 5000.97
DoD Instruction 5000.97 establishes policy, assigns responsibilities, and provides procedures for implementing digital engineering in the development and sustainment of defense systems. The issuance directs program managers to implement digital engineering practices to maximize the benefit and to support a comprehensive systems engineering program.
Digital Engineering Body of Knowledge (DEBoK)
The DEBoK is an interactive knowledge base that provides referential resources for the implementation of Digital Engineering (DE) where stakeholders can quickly build solutions predicated upon a common knowledge base containing resources, data, contracting language, metrics, training, and ecosystems and tools in a controlled manner.
