Preface

Hundreds of books, white papers, and articles deal with Enterprise Architectures (EA). They address important questions and create inspiring views, some of which are referenced in this book. But they are unlikely to answer business people’s or executives’ questions about enterprise architecture management (EAM). The current documented body of knowledge in this domain focuses on engineering techniques such as modelling, patterns, reference architectures, tools, repositories and so on. But if we want to unleash EA’s benefits, we need to better understand its management context; in other words, we need to value EAM as a top management topic. If we therefore focus on management, this should appeal to allbusiness people. And the emphasis on enterprise architecture should catch the attention of the executive management, as EA describes and can help develop organisational capabilities and assets. To test our views, we visited organisations of various sizes from different industries and countries. We wanted to see how they manage their enterprise architecture. We talked to people in business and technology departments, to C-level managers, project managers and enterprise architects. We sought out their best practices, lessons learnt, dos, and don’ts.
