This article describes the evolution of the Department of the Interior Enterprise Architecture (IEA) from an underdeveloped stated focused primarily on technology architecture, to its current position as a recognized leader in agency enterprise architectures, selected as best among all OMB rated EA programs in July 2005 and April 2006. This article is the second of two parts — Part I appeared in the previous issue of the JEA, and covered DOI background information, early shortcomings of the IEA effort, and subsequent improvements in IEA, including the development of key fundamentals. Part II presents both the “Major Changes” to IEA and the milestones and approaches in the IEA effort. The final “Major Change” presents information on a methodology developed by the IEA team known as MBT, or the Methodology for Business Transformation.
