The Zachman Framework of enterprise architecture. The Zachman Framework is an enterprise ontology and is a fundamental structure for enterprise architecture which provides a formal and structured way of viewing and defining an enterprise. The ontology is a two dimensional classification schema that reflects the intersection between two ...
Enterprise architecture regards the enterprise as a large and complex system or system of systems. [3] To manage the scale and complexity of this system, an architectural framework provides tools and approaches that help architects abstract from the level of detail at which builders work, to bring enterprise design tasks into focus and produce valuable architecture description documentation.
It treats Enterprise Architecture as not including merely diagrams and technical descriptions, but gives a holistic view that includes US legislative requirements and guidance, as well as giving technologists a better understanding of business needs with a quick explanation of the value chain for a business as outlined by Michael Porter.
The Zachman Framework provides the broad context for the description of the architecture layers, while EAP focuses on planning and managing the process of establishing the business alignment of the architectures. [2] EAP is planning that focuses on the development of matrixes for comparing and analyzing data, applications, and technology.
Architecture description practices, as described in IEEE Std 1471-2000, utilize multiple views to address several areas of concerns, each one focusing on a specific aspect of the system. Examples of architecture frameworks using multiple views include Kruchten's "4+1" view model, the Zachman Framework, TOGAF, DoDAF, and RM-ODP.
The Zachman Framework according to Zachman (2008) [9] is "a schema – the intersection between two historical classifications that have been in use for literally thousands of years". "The first is the fundamentals of communication found in the primitive interrogatives: What, How, When, Who, Where, and Why.

ISO/IEC/IEEE 42010:2011 defines requirements on the description of system, software and enterprise architectures.It aims to standardise the practice of architecture description by defining standard terms, presenting a conceptual foundation for expressing, communicating and reviewing architectures and specifying requirements that apply to architecture descriptions, architecture frameworks and ...
