Several times in my Enterprise Architecture (EA) practice, people asked me which framework shall I adopt or what are the benefits of the Zachman framework over TOGAF, etc. Others asked me to help them to define their own corporate EA framework. Before answering these types of questions, it is important to kw what the differences and commonalities are of these frameworks and standards. This book explains the role of Enterprise Architecture Frameworks and shows the differences between the most popular Enterprise Architecture Frameworks w a day available in the world. With the growing importance of Enterprise Architecture [EA]; at the same time, the discussion started how to create or choose the right Enterprise Architecture Framework & Tools for your organisation in the jungle of the existing ones. Giving an overview of the history of most Enterprise Architecture frameworks as well as their purpose, scope, principles, structure, guidance and compliance, will support you in identifying the usefulness of these Enterprise Architecture frameworks for your own situation. For the in-depth details of the described Enterprise Architecture Frameworks, references to the original sources of information are added in the chapter References & Bibliography. Separate chapters are addressing the most popular Enterprise Architecture tools on the market and their support of existing frameworks.
