Characterization of Enterprise Architecture quality attributes

Enterprise Architecture (EA), with its numerous and pervasive models, can support decision making on enterprise-wide issues. To provide such support, EA models should be amenable to analysis of various quality attributes. The prerequisite to providing this is to define and characterize EA quality attributes explicitly. This paper proposes the idea of EA quality attributes and their characterization by using EA quality attribute general scenarios. Also a meta-model is presented for their purpose of definition. Finally, as a sample of EA quality attributes, EA maintainability has been defined and characterized.
