The book attempts to answer a few of the common questions related to Enterprise Architecture (EA) and SOA. What are the issues? What is EA? Why should an organization consider EA? How to build the Enterprise Architecture and document it. What are the roadblocks, politics, governance, process and design method? How to measure the value deliverd by EA and its maturity and and how to select an Enterprise Architect? An innovative EA Framework, the associated metamodel and generic Enterprise Reference Maps (templates) for the business process, applications and infrastructure layers are proposed. The framework looks like a content page showing the chapters of a book or, in this case, the components of the Enterprise Architecture without actually describing them but showing how they fit into the whole. The book then identifies and summarises Best Practices in the Enterprise Architecture and SOA development, EA patterns, the integration to the mundane solution architecture, delivery checklistsÉ The book is intended to be a document summarising why and how to build an Enterprise Architecture.
