The Zachman framework is a logical structure intended to provide a comprehensive representation of an information technology enterprise. It allows for multiple perspectives and categorization of business artifacts. The brainchild of John Zachman who conceived the idea in 1987, the full technical name is Zachman Framework for Enterprise Architecture and Information Systems Architecture.
The Zachman framework gathers and refines principles from older methods. It has a structure (or framework) independent of the tools and methods used in any particular IT business. The framework defines how perspectives are related according to certain rules or abstractions. A framework takes the form of a 36-cell table with six rows (scope, business model, system model, technology model, components, and working system) and six columns (who, what, when, where, why, and how).
The Zachman framework is seen by some business managers as an ideal set of rules for the management of complex and evolving IT enterprises.
