Enterprise architecture (EA) is a comprehensive approach to designing and managing information technology and business structures in organizations. This journal aims to investigate the importance of building an integrated and efficient EA in achieving business excellence. We use a research methodology approach to analyze case studies and results related to EA implementation in several organizations. Our findings show that an integrated and efficient EA can provide benefits such as improved operational efficiency, cost savings, increased flexibility, and better decision-making. In this journal, we describe the methods used in building EAs, the results of EA implementation in organizations, and a discussion of the implications and resulting benefits.
