Modify TOGAF ADM for Government Enterprise Architecture : Case Study in Ethiopia

Abstract

Enterprise architecture is a conceptual blueprint that describes the structure and operation of the government and its elements. It provides a clear picture of the government where they are and where they want to be. In addition, it also addresses the issue of complexity and goes beyond IT in order to increase the simplicity of business processes across the country. The aim of this paper is to modify TOGAF ADM for the government enterprise architecture in order to improve the performance of the government enterprise. We have used eight steps to customize and modify TOGAF ADM for the government level. The modified TOGAF ADM comprises at the top Government Strategic Objective (i.e. it aims to align and formulate the overall strategic plan and policy across in both federal and regional government), Preliminary phase, Phase A-Phase H, and outside there is Security Architecture because it needs for all phases of the ADM. The modified TOGAF ADM provides basic guidelines for the government in order to align strategic objectives with the opportunity for the transformation of the country. It accelerates the prioritization of government goals, commitment, and communication between government actors and the implementation of government interoperability. This modified TOGAF ADM can be applied to the government-wide enterprise across the country. Therefore, the modified TOGAF ADM can be used for designing enterprise architecture for government across the country.
