Abstract or Description
Despite laudable case-by-case efforts, there is today no method for tracking interoperability on a comprehensive or systematic basis. This technical note presents best practices for measuring systems interoperability and assisting military planners in the acquisition, development, and implementation of command, control, communications, computers, and intelligence (C4I) systems that are interoperable. The Levels of Systems Interoperability (LISI) Model, although immature, provides a structured and systematic approach for assessing and measuring interoperability throughout the systems life cycle. In addition to exploring the many complex issues surrounding the state of interoperability for military applications, next steps for promoting a deeper understanding of interoperability and recommended measures that will promote systems interoperability are presented.
