Aligning TOGAF and NAF - Experiences from the Norwegian Armed Forces

This paper reports on experiences from establishing a reference architecture framework for the Norwegian Armed Forces. Like a number of other nations and NATO agencies, the armed forces chose TOGAF as their architecture development methodology (ADM), and the NATO Architecture Framework (NAF) for metamodel and content organization. In order to make TOGAF and NAF work together and address the particular requirements of the armed forces, significant adaptation was required. Previous work has analyzed the combination of TOGAF and military frameworks on the high level, but no detailed mapping between TOGAF 9 and the NAF, DoDAF, or MODAF architecture content frameworks were available. Such a mapping is presented here. The resulting framework has been implemented as a set of UML profiles, and as the content structure for the national military architecture repository. It has been applied by a number of initiatives, ranging from enterprise capability maps to technical interoperability between systems and acquisition projects.
