This book provides a method to plan, develop, validate, or evolve the design of an enterprise architecture function so that it fully meets the organization's needs. The reader will benefit from this book in two ways. First, it provides a structured overview and orientation to the subject of architecture from an architecture function perspective. Second, it guides through the process of planning, building, and operating your own architecture organization based on a generic architecture function blueprint presented in the form of a pattern language offering a structured means for navigating, contextualizing, combining, and composing the architecture function patterns.

The topics of architecture in general and enterprise architecture in particular have become ubiquitous in the twenty-first century. The networked universal computing machine (the world computer) has directly or indirectly permeated virtually every aspect of our lives, transforming the way we cooperate, partner, create, and run businesses and plan, implement, and provide goods and services. What were originally distinguished as business and technology are merging and constituting a common business model backbone that is neither distinguishable in form nor in essence. At the same time, we find that dealing with, if not mastering, complexity has become the central challenge for modern enterprises. Successfully planning, designing, and operating business models today is increasingly synonymous with establishing and evolving their digital means and building materials. In summary, business ecosystems have gained significantly in potential through digital means on the one hand but have also become inherently more complex on the other—both in their breadth (many touchpoints) and in their depth (complex touchpoints). Architecture has become ever-present because of its enormous relevance for the enterprise-wide planning, construction, and operation of digital material constituting digitalized services and means.

The goal of the book was to strike a good balance between the aspects of holistic orientation, theoretical substance, and practical guidance—a consolidation of our architecture experiences at that time. When we thought about writing the book, the topic of solution architecture lacked a holistic framework that established a common, unified terminology and described architecture in a differentiated way.

Specifically, my book proposes how to design an architecture function so that it ultimately meets the expectations of the business for effectively developing, delivering, as well as operating digitalized services. My book will further outline what roles, services and processes, elaboration and reference methods, disciplines, or artifacts an architecture function is responsible for. It will make tangible to you the overall value proposition of an architecture function, as well as introduce an enterprise operating model into which architecture integrates as an organizational capability. In doing so, I do not reduce the term architecture function to the realm of IT but remain largely agnostic in the objective as well as normative portions of my book—agnostic regarding the nature of the contributions (e.g., business versus IT), the process models and attitudes employed (e.g., Agile, Waterfall, DevOps), the size of the enterprise, and other determining factors.
