At the heart of transitioning from traditional systems engineering to digital “model-based” engineering is the use of the Digital System Model (DSM). The DSM is a digital representation of a defense system, generated by all stakeholders that integrates the authoritative technical data and associated artifacts which define all aspects of the system for the specific activities throughout the system lifecycle. The DSM is captured in a set of digitally linked data sources and models to enable stakeholders to optimize their actions by working from an authoritative source of truth. As a result, information is more easily shared and traced, impact analysis can be automated to understand changes, and simulations can be performed quickly, enabling improved and innovative solutions.

In an effort to drive the community towards implementing Digital Engineering, the Office of the Deputy Assistant Secretary of Defense for Systems Engineering (ODASD(SE)) has built an integrated taxonomy. The purpose of the taxonomy is to provide stakeholders with the broad categories of technical data, models, and documentation that should be considered authoritative across the lifecycle. This workshop will provide a brief review of the DSM taxonomy. This is a participatory workshop that spans across two days. The goals for this workshop are to:

• Review and provide feedback on the DSM taxonomy.
• Brainstorm the resulting digital artifacts that will be produced from the DSM
• Define how to migrate the DSM into digital acquisition/engineering practice.

The term “Digital Model-based Engineering” (DMbE) was developed as part of an effort by the Model-Based Systems Engineering (MBSE) Infusion Task Team to identify what government organizations might expect in the course of moving to or infusing MBSE into their organizations. DMbE is intended to allow an organization to progress from documentation-based engineering methods to digital methods, which may provide greater flexibility, agility, and efficiency. The task team was established by the Inter-Agency Working Group on Engineering Complex Systems (IAWG), an informal collaboration among government systems engineering organizations.

This presentation provides the results of an in-depth IAWG study that defined DMbE and investigated what the government expects from the use of the approach. This presentation will provide the current demand signal for DMbE, identify prerequisites, expectations, initial challenges, and recommendations for government, academia, and industry.
