5. Definition of Interoperability The ability of two or more systems or elements to exchange information and to use the information that has been exchanged. - IEEE Standards Information Network. IEEE 100, The Authoritative Dictionary of IEEE Standards Terms, Seventh Edition. New York, NY: IEEE, 2000 The ability of systems, units or forces to provide services to and accept services from other systems, units or forces, and to use the services so exchanged to enable them to operate effectively together. - Department of Defense. Joint Pub 1-02, DoD Dictionary of Military and Associated Terms. Washington, DC: 2001. (2001).
