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

Format:Gebundene Ausgabe|Von Amazon bestätigter Kauf
ob man dieses Buch gut findet, hängt davon ab, woran und wie man daran arbeitet. Wenn man Forscher ist und eine Dissertation auf dem Gebiet schreiben möchte, wie man Unternehmensarchitekturen beschreiben kann, wie man das formal angeht und was auf dem Gebiet so gemacht wurde, wird man nicht umhinkommen, dieses Buch zu kaufen - auszuwerten und neben andere Werke zu dem Thema zu legen - zum Beispiel neben das, was im Forschungsgebiet "Software-Kartographie" getan wird
Wenn man allerdings als Praktiker arbeitet, dann wird einen das Buch nicht schnell weiterbringen, weil all der "feinfiligrane" Formalismus in der Praxis deutlich zu langsam ist und man sich dort nach der 80/20 Regel überlegen muss, wie man mit wenig Aufwand ausreichende Ergebnisse bekommt, um die aktuellen betrieblichen Erfordernisse zu erfüllen.
Zu dem "Inhaltsverzeichnis" siehe Beschreibung des Verlages - hier noch Nutzen pro Zielgruppe
* IT Manager: Werden dem Buch wenig abgewinnen
* Unternehmensarchitekten aus der Praxis können es schnell diagonal durchziehen und sich noch ein paar nützliche Tipps suchen
* die eigentliche Zielgruppe ist nach meiner Vermutung die "Academia" - was ja auch o.k. ist - nur wissen muss man es halt

Excellent Modelling Approach
18. Januar 2007
Format:Gebundene Ausgabe
This is first in its kind book that tackles enterprise architecture modeling with a holistic approach. Book presents a unified modeling approach for enterprise architecture and simplifies the relationship between architecture domains with a simple Meta model. It also deals with communication and analysis aspect nicely.
This does not provide any details about what architecture development process should be nor it gives any insight on choosing an architecture framework. So set your expectation before buying. AS book title says it is about modeling, communication and Analysis.

The Archimate language in detail
20. Juni 2011
Format:Gebundene Ausgabe|Von Amazon bestätigter Kauf
If you want to learn how to do Enterprise Architecture modeling, this book is for you. The book covers the Archimate language in detail.
The book starts off with a nice introduction to Enterprise Architecture. It explains the internal and external drivers and then goes on to introduce the current state of Enterprise Architecture in the industry.
It introduces EFQM, ISO 9001, COBIT, ITIL, CMMI, IEEE 1471-200, Zachman Framework, TOGAF, and MDA. There is a short introduction to each, but it is enough to put them in context.
The book the talks briefly about the description languages which include IDEF, BPMN, Testbed, ARIS, UML, and ADLs.
Next there is a nice chapter named Foundations. Foundations outline the fundamental ideas on which the author's approach is based. Topics include architectural complexity, describing enterprise architectures, and pictures, Models, and semantics.
The last chapter before heading full steam ahead into modeling is Communication of Enterprise Architectures. The book then has chapters on guidelines for modelling, viewpoints and visualisation, architecture analysis, architecture support, and tool support.
The book then has three nice size case studies and wraps up with a chapter on what is beyond enterprise architecture. The case studies are of sizable systems, they are not just three hello world projects.
This book is in full color which makes the diagrams easier to understand. The book is small so it is easy to keep by your side. I like the writing style of the authors, they make it an easy and enjoyable read.
This book has tons of diagram examples in it. I use Archimate when I do Enterprise Architecture models. I use SPARX EA, but there is also a free tool available named Archi: Archimate Modelling (just Google it).
All in all if you are an architect you owe it to yourself to check out this book and give Archimate a shot.

Great book for practical enterprise architectural modeling!
24. Februar 2010
Format:Gebundene Ausgabe|Von Amazon bestätigter Kauf
This book is not TOO big! and TOO thick!. That's very easy to read. I like many communication and modeling techniques so much.
This book also contains lots of good and clear model images which represents the various architectural views. All sample models for each architectural views was created by using ArchiMate modeling notation that the author wants to introduce in the book. I like the ArchiMate because it's easier than UML. But don't be worried about learning the ArchiMate, the notations are very close to UML. So, I can continue to use UML and BPMN with my job unless some clients prefer to use ArchiMate.
The author also explains technique for communicate the EA to various stakeholders and explains how to handle the level of abstractions. Another part of the book is the analysis technique, the technique for analyzing the models. This topic helps me so much for checking the models (both verifying and validating). Is it good enough? That's the question I always ask myself while modeling.
I just made decision to plan to use the book as a modeling guideline for my client soon.
This book is very practical for EA modeling!!! So, as the book said... it's for modeling, communication and analysis. It's a modeling-orientation!
