C4I Interoperability
Abstract
The Defense Information Systems Agency’s (DISA) Joint Interoperability Test Command (JITC) serves as the only joint element of the Department of Defense’s (DoD) Major Range and Test Facility Base (MRTFB) that operates primarily for Information Technology and National Security Systems (IT/NSS) Test and Evaluation (T&E) support missions. JITC executes the T&E mission in support of Command, Control, Communications, Computers and Intelligence (C4I). JITC is the DoD’s Sole Interoperability Certifier and the only Non-Service Operational Test Agency in the DoD. Interoperability is vital to the DoD’s success as it allows forces, units and/or systems of military services, and U.S. partners to share data, information, materiel, and services required to operate collaboratively. Operational testing addresses critical issues of a system's effectiveness in combat-like environments. Additionally, operational testing provides decision makers an independent evaluation to better understand the risks and capabilities of a system’s effectiveness, suitability, and cyber-security before fielding to the warfighters. JITC’s T&E efforts determine the degree to which the DoD is fielding interoperable, operationally effective, suitable, and cyber survivable joint warfighting capabilities to achieve DoD’s goal of information superiority. JITC has the unique mission to provide consistent, structured, and effective T&E services that include operational, joint interoperability, and Test, Evaluation, and Certification (TE&C). JITC evaluates conformance to applicable Military Standards and technical specifications and performs Cyber T&E of DoD IT and NSS (including Cloud services and Mobility). JITC is responsible for: • Evaluating DoD IT/NSS for Joint/Coalition (involving two or more US military services and/or partner nations) interoperability • Issuing Joint Interoperability Certifications and Assessments • Conducting operational evaluations • Maintaining a federated IT infrastructure which provides a shared ruleset for how networks interact (a MRTFB activity) • Providing interoperability mission support to warfighters to enable effective communication and operations between US military services and other foreign nations
