An Enterprise Architecture framework for application consolidation in the Swedish Armed Forces

Abstract

In this paper, application consolidation using Enterprise Architecture methods is considered, with an ongoing project in the Swedish Armed Forces as the point of departure. The decision-making features of application consolidation are first analyzed and formalized from the perspective of decision theory. Applying these insights, a more practical framework is then proposed, based primarily on the ISO/IEC 9126 standard, the Ministry of Defence Architecture Framework (MODAF), and the formalism of Probabilistic Relational Models (PRM). This framework supports cost-benefit analysis of application consolidation decision-making, thus helping to make these decisions more structured and transparent.
