NESI, or Net-centric Enterprise Solutions for Interoperability is a joint effort between the Unite States Navy’s Program Executive Office for C4I & Space and the United States Air Force’s Electronic Systems Center. It provides implementation guidance which facilitates the design, development, maintenance, evolution, and use of information systems for the Net-Centric Operations and Warfare (NCOW) environment. NESI has also been provided to other Department of Defense (DoD) services and agencies for potential adoption.
