What is Zachman?

The Zachman Framework is an enterprise architecture framework that provides a structured way of viewing and defining an enterprise. It's essentially a schema – a logical structure – for classifying and organizing the descriptive representations of an enterprise. It provides a set of perspectives (what, how, where, who, when, why) across different stakeholder groups (planner, owner, designer, builder, implementer, worker). It is used to ensure completeness in enterprise architecture design and to facilitate communication between different stakeholders involved in enterprise systems development.
