The NATO Architecture Framework (NAF) provides the rules, guidelines and product descriptions that define a standard way of developing, organizing and presenting enterprise architecture. It also provides guidelines on how to describe communication and information systems. When this framework is applied, architectures are able to effectively contribute to the acquisition and fielding of cost-effective and inter-operable military capabilities. The framework ensures that architectures developed by NATO and its member countries can be compared and related across NATO and National boundaries.

A NAF implementation tool should be able to generate standardized documents that deal with enterprise architectures and that support the search for sponsorship and funding of major mission-oriented systems.

HOPEX NAF is designed to generate NAF deliverables. It is based on the standard features of HOPEX, however, dedicated features have been introduced to guide the NAF expert to use the product with the vocabulary with which he/she is accustomed.

The framework details all the views addressing the different aspects of enterprise architectures:
