Summary: The importance of capabilities in defense domain led to its inclusion in a number of Enterprise Architecture frameworks for this domain, including DoDAF, MODAF and NAF. These frameworks include a number of concepts and language constructs to describe capabilities in an organization. Despite the support for the representation of capabilities in theses frameworks, the notion of capabilities requires a precise conceptualization. A lack of this precision may lead to modeling and communication problems. Thus, this paper presents an ontological analysis of capability-related concepts in these defense frameworks
(DoDAF, MODAF and NAF), revealing issues in the underlying conceptualization and in the use of the capability concept. In this analysis, we adopt an ontological account for capabilities based on the notion of dispositions, derived from UFO. UFO helps to understand the constructs of defense frameworks and reveals issues about expressiveness and clarity in representation of capabilities. These issues form a start point to propose a review of the meta-models of defense frameworks, changing naming conventions of some concepts and including new concepts, relations and distinctions necessaries in the reviewed meta-model. Thus, improving the expressiveness and clarity of the language, to represent capabilities. This review allows equip the defense frameworks with appropriate support for representation of capabilities, ensuring the precision, clarity and expressiveness of its language concepts.
