# Digital Engineering Strategy **Domain:** Systems engineering / Defense acquisition **Doc Type:** Developed Policy Node **Maturity:** Developed **Collection:** [[collections/Gamification|Gamification Collection]] ## Definition The **Department of Defense Digital Engineering Strategy** is a policy framework for using authoritative models and data across a system's life cycle, connecting engineering activity through digital environments rather than relying primarily on disconnected documents. ## Significance The strategy formalizes a passage from representation to institutional action: models become shared working surfaces for design, testing, acquisition, operation, and sustainment. This increases coordination but also raises questions about provenance, model authority, access, and the ability to correct the source on which downstream decisions depend. ## Routes [[wiki/Authoritative Source of Truth|Authoritative Source of Truth]] · [[wiki/Digital Twin|Digital Twin]] · [[wiki/Operational Terrain of Meaning|Operational Terrain of Meaning]] · [[wiki/Common Data Layer|Common Data Layer]] ## Sources - [[articles/gamification/America Loves Games and the Home Court Advantage|America Loves Games and the Home Court Advantage]] - [U.S. Department of Defense, Digital Engineering Strategy](https://www.cto.mil/wp-content/uploads/2018/06/2018-DES.pdf)
