NIST Enterprise Architecture Model (NIST EA Model) is a late-1980s reference model for enterprise architecture. It defines an enterprise architecture [ 1 ] by the interrelationship between an enterprise's business, information, and technology environments.
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.

The cost and complexity of the framework has resulted in bills from both houses of Congress that direct NIST to create Cybersecurity Framework guides that are more accessible to small and medium businesses.
