Interoperability is the capability of systems, units, or forces to provide data, information, material, and services to and accept the same from other systems, units, or forces and to use the data, information, materiel, and services so exchanged to enable them to operate effectively together. Information technology (IT) and National Security System (NSS) interoperability include both the technical exchange of information and the operational effectiveness of that exchanged information as required for mission accomplishment.

The policies for interoperability are found in CJCSI 3170.01 series, JCIDS Manual, and CJCSI 6212.01 series. The following are key aspects of these policies:
- Global Information Grid (GIG): The globally interconnected, set of information capabilities, associated processes and personnel for collecting, processing, storing, disseminating, and managing information on demand to warfighters, policymakers, and support personnel. The GIG includes all owned and leased communications and computing systems and services, software (including applications), data, security services, and other associated services necessary to achieve information superiority.
- GIG Technical Guidance (GTG): evolving web-enabled capability providing the technical guidance necessary for an interoperable and supportable GIG built on net-centric principles.
- Architecture Viewpoints and DoDAF-Described Models: An architecture viewpoint is a selected set of architectural data that has been organized to facilitate visualization in an understandable way. An Architectural Description can be visualized in a number of formats, such as dashboard, fusion, textual, composite, or graphics, which present data and derived information collected in the course of the development of an architectural Description. A view is only a presentation of a portion of the architectural data, in the sense that a photograph provides only one view of the object within the picture, not the entire representation of that object.
- Interoperability and Supportability (I&S) Certification: I&S Certification verifies adherence to the Net-Ready Key Performance Parameter (NR-KPP) throughout the life cycle by analyzing requirements documents, ISPs, and testing plans for appropriate requirements characterization and execution of the five elements of the NR-KPP. The requirement for I&S Certification of IT and NSS capabilities for Acquisition Category (ACAT) programs will be determined during the JCIDS process and will be updated prior to each milestone and reviewed prior to recertification every four years, or when significant changes occur throughout the operational life of a system. The Joint Staff, J-6 will perform I&S certification for JROC & JCB Interest and Joint Integration documents (Capability Development Document (CDD) and Capabilities Production Document (CPD) and the associated Information Support Plan (ISP) or Tailored ISP. I&S certification authority is delegated to C/S/As for ACAT II and below programs of record without joint interface requirements.
