Frequently Asked Questions

What is an enterprise architecture framework?

An EA framework is a structured method and vocabulary for describing and planning an organization's business, data, application and technology architecture, so that strategy and IT investment stay aligned.

How do TOGAF, Zachman and ArchiMate differ?

TOGAF is a process framework built around the Architecture Development Method, the Zachman Framework is a classification schema for architecture artifacts, and ArchiMate is a modeling language for drawing architectures. Many teams combine them.

Which framework should I start with?

For general enterprise architecture, many teams start with TOGAF and model in ArchiMate; defense and government work often uses DoDAF, UAF or FEAF-derived approaches; cloud teams use the Well-Architected and adoption frameworks.

Is the Federal Enterprise Architecture still current?

The page linked here is an archived White House page, so treat FEA as a historical reference and check current US federal guidance.

How current is this page?

Links were checked in October 2026. Standards bodies revise their frameworks and tool vendors merge often, so confirm the current version and ownership on each vendor's site. Sites that block automated checks (DoD CIO and Sparx Systems; the erwin link returns 202) are kept and may need a manual click.
