Book Description

An enterprise architecture tries to describe and control an organisation’s structure, processes, applications, systems and techniques in an integrated way. The unambiguous specification and description of components and their relationships in such an architecture requires a coherent architecture modelling language.

Lankhorst and his co-authors present such an enterprise modelling language that captures the complexity of architectural domains and their relations and allows the construction of integrated enterprise architecture models. They provide architects with concrete instruments that improve their architectural practice. As this is not enough, they additionally present techniques and heuristics for communicating with all relevant stakeholders about these architectures. Since an architecture model is useful not only for providing insight into the current or future situation but can also be used to evaluate the transition from ‘as-is’ to ‘to-be’, the authors also describe analysis methods for assessing both the qualitative impact of changes to an architecture and the quantitative aspects of architectures, such as performance and cost issues.

The modelling language and the other techniques presented have been proven in practice in many real-life case studies. So this book is an ideal companion for enterprise IT or business architects in industry as well as for computer or management science students studying the field of enterprise architecture.

The modelling language presented has been proven in practice in many real-life case studies and has been adopted by The Open Group as an international standard.

The books main theme is about how to achieve Business-IT alignment through the use of enterprise architecture. The modelling part is by far the most important part of the book. Here the ArchiMate language is defined, which is an open and independent language for enterprise architecture.

A current problem in enterprise arcitecture is that stakeholders within different architecture domain operates with their own models and that the relationships between the concepts in these models seldom are clear. ArchiMate attempts to remove these ambiguities by creating a unified meta-model of EA across the three architectural domains: Business, Application and Technology.

The model itself is surprisingly simple - and dare I say - elegant. It's safe to say, that ArchiMate takes a service oriented approach to enterprise architecture. It is also worth noting, that ArchiMate is not an attempt to replace specialised modelling languages such as UML or BPMN.

It is also worth noting, that ArchiMate is being adopted by The Open Group (under TOGAF)

The good:

Very ambitious attempt at creating a unified and coherent meta-model for enterprise Aarchitecture. Excels in describing the need for a coherent language as well as describing the ArchiMate language. The book is very scholarly written and there is little if any hype.

The bad:

The level of ambition and the scholary nature of the book make for a very dense read. But not only that - the parts dealing with communication and analysis seems less approachable and less applicable than the modelling part.

Overall:

It's hard not to applaud this attempt at creating a unified and holistic way to model and describe enterprise architectures. One can only hope that initiatives like this will take hold. A dense read for sure - but well worth it.

5.0 out of 5 stars best EA book I have found so far... 30 April 2010
Format:Hardcover
Great book! It presents a rigorous approach to enterprise architecture modelling with the aim of assuring consistency and traceability between views defined at different levels of abstraction. There are not many pubblications out there that cover the modelling aspect of enterprise architecture in such a depth. The text has an academic "cut" that sometimes makes it a bit heavy...but it is certainly worth the effort!

5.0 out of 5 stars My favourite book on EA 29 Nov. 2011
Format:Hardcover
This book is a must have for practising enterprise architects involved in architecture modelling and managing an architecture repository.

The ArchiMate meta model presents a significant learning curve, but this book is my "go to" resource when I'm trying to figure something out.

ArchiMate is becoming a very useful tool for Enterprise Architects and, especially, Solution Architects.

This book also includes a very useful and readable overview of architecture frameworks.

I have been taking it with me on airplanes and reading passages at random.
