The LISI Reference Model provides sufficient information to support architecture development and linkages between the operational, systems, and technical architecture views. The operational architecture view provides details about the required needline interactions between organizational nodes to determine the specific interoperability level required. Even before looking at systems or technical details, the particular details regarding who is exchanging information and what is the nature of the information exchanged enables a "table lookup" to the LISI Reference Model to identify the required interoperability level. For example, voice interaction between two low-level organizations requires a different interoperability level than multiple enterprise-level organizations that must collaborate on a multimedia product. The LISI Reference Model helps to frame the need for interoperability in specific and meaningful terms that can guide systems acquisition and design decisions.
In recent years, DoD has steadily enhanced its information technology architecture guidelines and tools. The DoD architectural community has produced an interrelated set of policies and guidance, including the TRM, the JTA, the DII COE and the C4ISR Framework. By defining the interoperability relationships DoD seeks between systems, LISI becomes an integral part of these guidelines. Specifically, the LISI Reference Model is designed to support the development and analysis of DoD architectures by helping to identify, up-front, issues, problems, gaps, and shortfalls that may be present within any information technology architecture.
