![]() Instead of representing the process as a series of steps, he organized it around the points of view taken by the various players, providing organizations with an effective way of assessing the completeness of software development process models, in terms of an organization's information needs. In 1987, John Zachman published a different approach to the elements of system development. This is expressed as consisting of: Strategy, Analysis, Design, Construction, Transition and Testing. Many software methodologies are organized around the phases of the system development life cycle and the steps within each of these phases required to develop systems. Zachman Framework vs Traditional Software Process The framework draws on Zachman's experience of how change is managed in complex products such as airplanes and buildings. It is a proactive business tool, which can be used to model an organization's existing functions, elements and processes - and help manage business change. The Zachman framework provides a means of classifying an organization's architecture. Part of this difficulty is due to a lack of internal understanding of the complex structure and components in different areas of the organization, where legacy information about the business is locked away in the minds of specific employees or business units, without being made explicit. In today's complex business environments, many large organizations have great difficulty responding to changes. The Zachman Framework is an enterprise ontology and is a fundamental structure for Enterprise Architecture which provides a way of viewing an enterprise and its information systems from different perspectives, and showing how the components of the enterprise are related.Įnterprise Architecture is the process used by a business to make explicit representations of enterprise operations and resources, rather than relying on implicit notions or understanding in individual managers' heads. Enterprise Architecture (EA) is a discipline which has evolved to structure the business and its alignment with the IT systems.
