Cross community and interservice Live-Synthetic (Virtual-Constructive-Gaming) initiatives often fail due to the
lack of formalized governance, as stated by Frank DiGiovanni, Director, Force Readiness and Training in the Office
of the Deputy Assistant Secretary of Defense (Readiness), during the 2014 Interservice/Industry Training,
Simulation and Education Conference (I/ITSEC). In March 2014, the US Army initiated a cross community
Research and Development (R&D) initiative to investigate the feasibility of establishing a common Live-Synthetic
approach for the Training and Test & Evaluation (T&E) communities, called the Live-Synthetic Training and Test &
Evaluation Enterprise Architecture (LS TTE EA).
This paper reports on the progress of this initiative in establishing the objective framework for the enterprise
architecture (EA) that includes: (1) the initial governance approach, (2) the business architecture, and (3) the
reference architecture. The governance approach provides agreed-upon practices and interactions for the formalized
collaboration between organizations to build and deploy services that are useful and sustainable for the EA. The
framework for the development and evolution of the governance approach for the LS TTE EA is outlined, including
how the governance approach is being applied to current prototyping activities. The business architecture provides a
common understanding to align Army strategic objectives and tactical Training and T&E demands. Business
architecture artifacts and the results of a quick-look cost benefit analysis are discussed. The reference architecture is
the authoritative source of information that guides the implementation of EA solutions. The reference architecture
layers and initial documentation in Department of Defense Architecture Framework (DoDAF) viewpoints are
shown. Finally, the paper discusses the way forward for application of the EA objective framework to the Army’s
Integrated Training Environment (ITE), Integrated Live-Virtual-Constructive Test Environment (ILTE), and
Synthetic Training Environment (STE), and applicability to the Defense Training Environment (DTE).
