Abstract: Enterprise architecture frameworks (EAFs) provide tools and methods to categorise, document and depict interrelationship between enterprise business processes, stakeholders and information classes. It explicitly documents information generation, processing and consumption pattern facilitating communication and management. But there is a confusing variety of EAFs for organisations to choose from. There is no explicit guidance or justifiable rationale available to choose an EAF over others. This paper provides a rationale and attributes based evaluation of popular EAFs and conclude superiority of Zachman framework (ZF) for a software-driven enterprise (SDE). Further, this paper surveys salient aspects of different software technologies and provide an assessment framework to compare them and conclude suitability of agent technology for realising information system infrastructure of an SDE. This work makes a provocative argument that many of the modern EAFs are not suited for an SDE due to their affiliation to software technologies that are found to has several limitations.
