The demand signal for rapid decision-making support has increased. Thus, access to authoritative sim-ready data supporting an agile decision cycle is a critical requirement. Collecting and reformatting force structure, threat representation, systems performance data, and geospatial data for scenario development is manpower and time intensive. This led to a collaboration between the Army (AMSO) and Joint Staff to expand the scope of ongoing data efforts in order to drive the ability to access, retrieve, use, and reuse sim-ready data. The Joint M&S Data Initiative supports the National Defense Strategy by providing the overarching vision, focus, guiding principles, essential capabilities and goals necessary to transform not only the Army’s M&S Enterprise but sync with Joint Services into a common data framework.
