The Zachman Framework is a foundational enterprise architecture classification schema that organizes architectural artifacts into a two-dimensional matrix of six communication interrogatives (What, How, Where, Who, When, Why) against six stakeholder perspectives (Planner, Owner, Designer, Builder, Subcontractor, User).
Context for Technology Leaders
For CIOs and enterprise architects, the Zachman Framework provides a comprehensive taxonomy for organizing the vast array of descriptive representations needed to understand a complex enterprise. Unlike TOGAF, which provides a methodology, Zachman provides a classification structure that ensures completeness of architectural documentation. It helps enterprise architects ensure no critical perspective is overlooked when designing or evaluating enterprise systems.
Key Principles
- 1Classification Taxonomy: A 6x6 matrix organizing architectural artifacts by interrogatives and perspectives, ensuring comprehensive coverage of enterprise descriptions.
- 2Perspective-Based Views: Each row represents a different stakeholder perspective, from executive planner to end user, each with unique concerns and vocabulary.
- 3Completeness Assurance: The matrix ensures that all aspects of the enterprise are addressed, preventing gaps in architectural documentation.
- 4Framework Neutrality: Zachman is methodology-agnostic, serving as a classification scheme that can be used alongside any architectural methodology.
Strategic Implications for CIOs
The Zachman Framework helps CIOs ensure that enterprise architecture efforts are comprehensive and address all stakeholder perspectives. It supports governance by providing a structured way to evaluate whether architectural documentation is complete. Enterprise architects use it to identify gaps in existing documentation and to organize artifacts for different audiences. For board communication, Zachman's perspective-based approach helps translate technical architecture into business-relevant views.
Common Misconception
A common misconception is that the Zachman Framework is a methodology for creating enterprise architecture. In reality, it is a classification schema or ontology that organizes architectural artifacts. It does not prescribe how to create architecture; it provides a framework for ensuring completeness of what is documented.
