This project is an in-depth analysis of Enterprise Architecture (EA), using Johnson & Johnson as a case study. The project begins by identifying the main problems faced by the organization, such as a complex business environment and decentralized IT systems. It proposes the Zachman Framework as a solution, organizing existing functions, elements, and processes. The project then compares various EA frameworks including Zachman, TOGAF, FEA, and Gartner, evaluating their completeness, business focus, and time to value. It discusses the relationship between EA and SOA, highlighting the value that an EA program delivers, such as guidance and control, while also addressing associated risks like lack of understanding and user acceptance. The project further explores value creation through strategic planning, improved communication, and tactical improvements. It examines risk management methods, including mitigation and exploitation, and emphasizes the importance of aligning IT with business strategy. The project then delves into EA implementation methodologies, comparing frameworks and methodologies, and the importance of communication and stakeholder support. It also examines the phases of an EA implementation methodology, and the documentation used, including artifacts, diagrams, and vendor-supplied documentation.
