To further the digital engineering effort, SE&A leads the Digital Engineering, Modeling and Simulation (DEM&S) Community of Practice (CoP), whose participants represent segments of the engineering and acquisition communities including Program Executive Offices, Program Managers, engineering, and science and technology proponents. The DEM&S CoP promotes digital engineering principles throughout the Services and other agencies and can assist in advancing digital engineering practices.

The DEM&S CoP is assessing, promoting, and appropriately increasing the use of digital engineering in multiple areas related to acquisition. It relies on implementation instances to further increase the guidance, support, and use of products out of digital engineering: digital artifacts. In concert with its internal exploration, the CoP retains a close tie to the industrial sector for advice and advocacy and to address challenges in using digital artifacts across the government-industry boundary. The CoP is responsible for promoting and facilitating improvements in the expertise of digital engineering stakeholders in the acquisition workforce.
