is designed to be a classification schema for organizing architecture models. It provides a synoptic view of the models needed for enterprise architecture. Information Systems Architecture does not define in detail what the models should contain, it does not enforce the modeling language used for each model, and it does not propose a method for creating these models. Extension and formalization In the 1992 article "Extending and Formalizing the Framework for Information Systems Architecture" John F. Sowa and John Zachman present the framework and its recent extensions and show how it can be formalized in the notation of conceptual graphs. Also in 1992: Later during the 1990s Methodologists like Clive Finkelstein refocused on the top two framework rows which he labeled Enterprise Engineering and has one of the most successful methods for converging the business needs with information technology engineering implementation, and determining a logical build sequence of the pieces. Framework for enterprise architecture In the 1997 paper "Concepts of the Framework for Enterprise Architecture" Zachman said that the framework should be referred to as a "Framework for Enterprise Architecture", and should have from the beginning. In the early 1980s however, according to Zachman, there was "little interest in the idea of Enterprise Reengineering or Enterprise Modeling and the use of formalisms and models was generally limited to some aspects of application development within the Information Systems community". In 2008 Zachman Enterprise introduced the Zachman Framework: The Official Concise Definition as a new Zachman Framework standard. Extended and modified frameworks Since the 1990s several extended frameworks have been proposed, such as: Matthew & McGee (1990) extended the three initial perspectives "what", "how" and "where", to event (the "when"), reason (the "why") and organization (the "who"). Evernden (1996) presented an alternative Information FrameWork. The Integrated Architecture Framework developed by Capgemini since 1996. Vladan Jovanovic et al. (2006) presents a Zachman Cube, an extended of the Zachman Framework into a multidimensional Zachman's Cube. Zachman Framework topics Concept The basic idea behind the Zachman Framework is that the same complex thing or item can be described for different purposes in different ways using different types of descriptions (e.g., textual, graphical). The Zachman Framework provides the thirty-six necessary categories for completely describing anything; especially complex things like manufactured goods (e.g., appliances), constructed structures (e.g., buildings), and enterprises (e.g., the organization and all of its goals, people, and technologies). The framework provides six different transformations
