This book captures and communicates the wealth of architecture experience Capgemini has gathered as a member of The Open Group – a vendor- and technology-neutral consortium formed by major industry players – in developing, deploying, and using its “Integrated Architecture Framework” (IAF) since its origination in 1993. Today, many elements of IAF have been incorporated into the new version 9 of TOGAF, the related Open Group standard. The authors, all working on and with IAF for many years, here provide a full reference to IAF and a guide on how to apply it. In addition, they describe in detail the relations between IAF and the architecture standards TOGAF and Archimate and other development or process frameworks like ITIL, CMMI, and RUP. Their presentation is targeted at architects, project managers, and process analysts who have either considered or are already working with IAF – they will find many roadmaps, case studies, checklists, and tips and advice for their daily work.

Why, What, How

The Integrated Architecture Framework Explained

When I joined Capgemini back in 1996 I was amazed by investment that had been made in developing Enterprise Architecture, and at the root of this, the IAF methodology. Back in the mid 1990s the importance of architecture was dimly recognised but certainly it was not widely understood as a crucial element of successful enterprise wide IT implementation. A decade later with the huge growth in the role, the sophistication, and importance of Information Technology it has become recognized, and established for the value it brings. With this recognition has come various forms of ‘standardization’ ranging from the work of the Open Group and its moves to establish TOGAF as a common framework, together with ITAC to certify architects, through to a wide variety of product vendor architects, even to some industry sectors establishing their own architectures. Has this diminished, or even may be removed the need for IAF? Well it might have done if the world had stood still, but it hasn’t. Simul- neously the range and complexity of technology has increased, the functionality has been extended to embrace new front office capabilities and most of all the externalization and globalization of business has added a whole new extra dimension. Standardization might have improved connections and interfaces, and in so doing produced ‘systems’ of apparently limitless extendibility, but it has done little to improve the necessary ‘understanding’.

This book is positioned as a rst in a series of books on enterprise architecture needed for a Master of Enterprise Architecture program, and is targeted both at university students and practitioners with a drive to increase their understanding of these elds. As an introductory book, this book aims to explore the concept of enterprise architecture. At rst glance, writing such an introductory book might seem as a straight forward task of setting up a structure and lling in “the blanks. ” However, writing this book turned out to be a pleasant journey of discovery. Based on our past experiences, each of us had a clear understanding of enterprise architecture, based on several years of experience and insight in the eld. However, when we started writing this book, and each of us exposed our individual understandings, it became apparent that our understanding of the eld differed in several ways. This prompted several discussions leading to an abundance of new insights. Without exception, thesediscussionstookplaceina pleasantandopenatmosphere,fueledbyourshared driveforunderstandingandincreasedinsight. Wearenowevenmoreconvincedthan before, that the eld enterprise architecture is a true multi-disciplinary profession. In the resulting book, we would like to share our insights, while also hoping to continue our discussions, now also involving you as a reader. We also realise that the journey is still far from complete. While this introductory book provides an overview of the eld of enterprise architecture from the perspective of our insights, many aspects need further re nement.
