Since Stephen Spewak’s Enterprise Architecture Planning (EAP) in 1993, and perhaps before then, it has been normal to divide enterprises architecture into four architecture domains. Each framework possesses different strengths and weaknesses.Įnterprise architecture is unique to every organization, however, there are some common elements. They attempt to address the basic challenge of assessing, aligning, and organizing business objectives with technical requirements and strategies such as the Zachman Framework, The Open Group Architecture Framework (TOGAF), NAF, DoDAF, MoDAF and etc. Since then, many other EA frameworks have been published and are used by many organizations. There is no shortage of EA frameworks in the IT industry, Zachman was the first to formalize the concept and publish a framework. Practitioners of enterprise architecture, enterprise architects, are responsible for performing the analysis of business structure and processes and are often called upon to draw conclusions from the information collected to address the goals of enterprise architecture: effectiveness, efficiency, agility, and continuity of complex business operations. Thus, EA provides a blueprint for an effective IT strategy and guides the controlled evolution of IT in a way that delivers business benefit in a cost-effective way. Enterprise Architecture reduces redundancy, complexity and information silos and business risks associated with IT investments. Often compared with town-planning or urban design, enterprise architecture (EA) is a well-defined practice for conducting enterprise analysis, design, planning, and implementation for the successful development and execution of strategy.
