Enterprise architecture (EA) serves as a strategic framework that aligns an organization's business goals with its IT infrastructure, enabling more effective decision-making, streamlined processes, and agile adaptation to change. As businesses face rapid digital transformation, globalization, and complexity in operations, EA becomes a critical tool for achieving organizational coherence and resilience. Implementing and maintaining EA practices comes with some challenges. From securing stakeholders to managing new technologies and ensuring alignment across businesses, organizations must navigate a range of technical, organizational, and cultural challenges. Exploration of Practices and Challenges in Enterprise Architecture delves into the core practices of enterprise architecture for business governance. It examines the key challenges that impact its successful adoption and sustainability in dynamic business environments. This book covers topics such as e-business, software engineering, and organizational development, and is a useful resource for computer engineers, business owners, academicians, researchers, and scientists.
