Most organisations have problems to explain and manage the economic benefits of Enterprise Architecture. Managers often asked me what Enterprise Architecture can do for me. At the same time several Governmental organisations are adopting Enterprise Architecture as part of their change and E-Government initiatives. A holistic Enterprise Architecture approach can deliver a lot of benefits to organisations depending on the focus where to find these benefits. Even so Enterprise Architecture delivers the foundation for Enterprise Portfolio Management, the ultimate business driver for Enterprise Architecture. The main purpose of this book is achieving awareness at management level as well as at enterprise architects level about adopting an economic approach when dealing with Enterprise Architecture programs. This book explains the areas of economic benefits of Enterprise Architecture programs, the different views as well as a holistic approach to show the areas of economic benefits. Economic methods, models and approaches are described in short to show, how to quantify and manage the economic benefits of Enterprise Architecture programs as well as how Enterprise Architecture supports Enterprise Portfolio Management. This book has not the intention to be a scientific research document, nor a handbook to deliver solutions for all your EA related economic issues.
