This article describes the evolution of the United States Department of the Interior (DOI) Enterprise Architecture (EA) from an under-developed state that primarily focused on the technology architecture to its current position as a model for other agencies. This was evidenced by the high rating of DOI’s EA (4.0 out of 5.0) among all federal EA programs in June 2005 from the Office of Management and Budget. This article presents the evolution of the Department’s EA over the past three years in terms of the development and application of a set of techniques that have facilitated business transformation at a sustainable rate while achieving broad organizational buy-in. This article will also include a detailed examination of various approaches to EA, a discussion of key fundamentals identified during the process and lessons learned.
