Item description for Enterprise Architecture by P. Johnson & M. Ekstedt...

In the last decade, enterprise architecture has grown into an established approach for management of the information systems in an organisation. Enterprise architecture is model based, in the sense that diagrammatic descriptions of the systems and their environment constitute the core of the approach. The purpose of enterprise architecture models is to support the making of rational decisions about information systems in an organisation. This book emphasises the decision-supporting potential of enterprise architecture.

Reviews - What do customers think about Enterprise Architecture?

Goal-Oriented Enterprise Architecture  Jul 7, 2008
One of the biggest possibilities and problems in enterprise architecture is that there are many potential uses for it. It is not rare that enterprise architecture projects end up trying to use it for everything at the same time; ensuring business/IT-alignment, consolidating the IT system portfolio, managing costs, taking control of the IT investment process, and assessing system properties such as information security, system flexibility and interoperability.

This book presents an approach to enterprise architecture that starts with a clear definition of the purpose of the present enterprise architecture effort, and then aims to keep the rest of the architecture work closely focused on that purpose, thus preventing architecture projects from becoming large and unfocused.

The book is structured so that it is possible to jump between the chapters rather being forced to read from the beginning to the end. The largest part of the book describes the different potential goals of the enterprise architecture effort. There is one chapter concentrating on business goals such as increasing the operational efficiency and improving the business strategy. Another chapter is concerned with goals related more to the IT systems themselves, such as the improvement of the interoperability or maintainability of the systems. A third chapter is focused on the IT organization, considering how enterprise architecture may be employed to improve its performance.

The idea behind the proposed approach is then that the chosen goals should determine what architecture models will be employed. By only allowing models that support the chosen goals, the enterprise architecture project is delimited. A set of models are therefore presented and their relations to the previously presented goals are discussed.

There is also a chapter on how to organize an enterprise architecture effort, and there is a final chapter presenting a case study.
