In 1989, the National Institute of Standards and Technology (NIST) published the [[NIST Enterprise Architecture Model]].<ref>W.B. Rigdon (1989). ''Architectures and Standards''. In Information Management Directions: The Integration Challenge (NIST Special Publication 500-167), E.N. Fong, A.H. Goldfine (Eds.), Gaithersburg, MD: National Institute of Standards and Technology (NIST), pp.135-150.</ref> This was a five-layer reference model that illustrates the interrelationship of business, information system, and technology domains. It was promoted within the U.S. federal government. It was not an EA framework as we see it now, but it helped to establish the notion of dividing EA into architecture domains or layers. The NIST Enterprise Architecture Model seemingly was the first publication that consistently used the term "Enterprise Architecture".<ref name="HISTORY" />

In 1990, the term "Enterprise Architecture" was formally defined for the first time as an architecture that "defines and interrelates data, hardware, software, and communications resources, as well as the supporting organization required to maintain the overall physical structure required by the architecture".<ref name="HISTORY" /><ref>{{cite journal | last1 = Richardson | first1 = G.L. | last2 = Jackson | first2 = B.M. | last3 = Dickson | first3 = G.W. | year = 1990 | title = A Principles-Based Enterprise Architecture: Lessons from Texaco and Star Enterprise | url = | journal = MIS Quarterly | volume = 14 | issue = 4| pages = 385–403 | doi=10.2307/249787| jstor = 249787 }}</ref>

In 1992, a paper by Zachman and Sowa<ref name="JZ 1992">Zachman and Sowa (1992) ''Extending and formalising the framework of information systems architecture'' IBM Systems Journal, Vol 31, No 3</ref> started thus "John Zachman introduced a framework for information systems architecture (ISA) that has been widely adopted by systems analysts and database designers." The term enterprise architecture did not appear. The paper was about using the ISA framework to describe, “...the overall information system and how it relates to the enterprise and its surrounding environment.” The word enterprise was used as a synonym for business.
