Arkitekturarbeid i Forsvaret med forenklet bruk av NATO Architecture Framework (NAF)

In this report, we introduce a significantly simplified version of the NATO Architecture Framework (NAF), which we have termed the ”NAF Core”, as well as a methodology concept in which this core framework forms the basis for locally adapted architecture work. The”NAF Core” is intended to support holistic collaboration between diverse communities of interest within the defence sector. We attempt to draw up a generic guide for the use of our NAF Core, in which local methodology requirements are met while retaining interoperability across domains. Our work partially builds on experiences gathered during a series of meetings with selected stakeholders during the autumn of 2011. The goals of these meetings were to understand stakeholder requirements and prerequisites for architecture methodology, elicit input for further development of tailored architecture methodology and finally to explore the possibilities for reuse of existing architecture models. What we learned during these meetings guided us in our work to define a simplified architecture methodology. Our previous assumptions about a sensible approach were confirmed. This assumption was that our national approach to architecture work must foster increased participation, and must – for most user groups – rely on external support. A balance between centralized governance and decentralized execution seems conducive. We explore the utility of our proposed architecture methodology through an exercise aimed at supporting the Norwegian Cyber Command in their efforts to define architecture methodology which supports efficient program management. Based on the methodology requirements associated with managing the information infrastructure program area – which we describe as capabilities that the Defence Force must be able to realize in their architecture work – we define a rather large collection of required services. Finally, we assess the merit of different solutions in realizing some of these services. We recommend that our proposals regarding simplified and tailored methodology form the basis for the further development of guidelines for architecture work in the Norwegian military sector. These guidelines should support a low threshold for participation, which will promote increased promulgation of the use of interoperable methodology. We hope that the architecture capabilities and services which we have defined in this report will represent a useful starting point for relevant communities of interest in their quest to adapt their work methodologies to the high complexity problem space they are faced with in realizing a relevant, agile and cost effective defense force.
