Organizations are discovering that information systems are very complex and these systems rarely produce real business value for the organization (Session, 2007). Businesses are looking for an answer, and that answer may be for an organization to develop an enterprise architecture (EA). The complexity and constant change that occurs in the business world can be controlled by developing an EA, and this will facilitate alignment between business objectives, business processes and information systems (Ylim & Halttunenb, 2007). This can reduce system function redundancies, existing data redundancies, and help integrate data into meaningful information for various levels within the organization. Developing a usable EA is not an easy task, but using one of the available frameworks should help you accomplish this task. The framework provides guidelines for documentation that must be considered and present in an enterprise architecture (Bernard, 2005). There are many frameworks available today, but one of the oldest and currently in use is the Zachman Framework produced by John Zachmann. This framework offers advantages but also has limitations. Another framework will be compared to Zachman's, namely the Open Group Architecture Framework (TOGAF). Each framework will be described along with the various terms that need to be clarified. Eventually, it will become clear that the best way to separate an organization is to take the best aspects of the various frameworks and combine these attributes into the organization's own framework. To begin, each framework will be described, definitions of key terms will be presented, and a detailed discussion will be presented.
