'''Test and Training Enabling Architecture''' ('''TENA''') is an architecture designed to bring interoperability to United States Department of Defense test and training systems. TENA is designed to promote integrated testing and [[Simulation-based acquisition|simulation-based acquisition]] through the use of a large-scale, distributed, real-time synthetic environment, which integrates testing,
training, simulation, and high-performance computing technologies, distributed across many facilities, using a common architecture.<ref>TENA-2012-Paper-Final from the Test and Training Enabling Architecture (TENA) Website [https://www.tena-sda.org/download/attachments/6750/TENA-2012-Paper-Final.pdf]</ref>

* Enable Interoperability among Range systems, Facilities, Simulations, C4ISR systems in a quick, cost-efficient manner,
* Foster Reuse for Range asset utilization and for future developments
* Provide Composability to rapidly assemble, initialize, test, and execute a system from a pool of reusable, interoperable elements

__TOC__

==Overview==

TENA recognizes five basic categories of [[Software|software]]:
# TENA Applications (Range Resource Applications and TENA Tools) – Range Resource Applications are range instrumentation or processing systems (software applications) built to be compliant with TENA and are the heart of any TENA execution. TENA Tools are generally reusable TENA applications, stored in the repository and made available to the community, that help facilitate the management of a logical range through the entire range event lifecycle.
# Non-TENA Applications – range instrumentation/processing systems, systems-under-test, simulations, and C4ISR systems not built in accordance with TENA but needed for a test or training event.
# The TENA Common Infrastructure – those software subsystems that provide the foundation for achieving TENA’s goals and driving requirements. These include the TENA Repository, as a means for storing applications, object models, and other information between logical ranges; the TENA Middleware, for real-time information exchange; and the Event Data Management System, for storing scenario data, data collected during an event, and summary information.
# The TENA Object Models – the common language used for communication between all range resources and tools. The set of objects used in a logical range is called the “logical range object model (LROM)” and may contain TENA standard object definitions as well as non-standard (user-defined) object definitions.
# TENA Utilities – applications specifically designed to address issues related to usability or management of the TENA logical range.
