The Practice of Enterprise Architecture: A Modern Approach to Business and IT Alignment (NO RENEWALS)

Enterprise architecture (EA) is a set of descriptions relevant to both business and IT intended to bridge the communication gap between business and IT stakeholders in organizations, facilitate information systems planning and improve business and IT alignment. Due to complex historical reasons, the notion of enterprise architecture was always surrounded by endless speculations, dangerous myths, non-existing best practices, unfulfilled promises, expensive failures and grave disappointments. Traditionally the entire discourse around enterprise architecture was dominated by shallow advice and faddish approaches (e.g. well-known EA frameworks) infinitely distant from the practical realities, but nonetheless aggressively promoted by commercially motivated consultancies and gurus. At the same time, realistic and trustworthy information on enterprise architecture is still incredibly hard to find in any available sources. Based on an extensive study of the actual industry best practices and existing EA literature, this book provides a unique, systematic, end-to-end description of various aspects of an EA practice integrated into a consistent logical picture. In particular, this book offers clear, research-based, conceptually sound and practically actionable answers to the key questions related to enterprise architecture: What is the meaning of enterprise architecture and an EA practice? What processes constitute established EA practices and how do they work? What EA artifacts are used in successful EA practices and how? What is the best way to structure architecture roles and functions? What software tools and modeling languages are necessary for enterprise architecture? How to initiate an EA practice in organizations from scratch and evolve it? Where do current EA best practices originate from? This book is organized in a highly structured, sequential manner and does not require any prior knowledge of enterprise architecture. The book is intended for a broad audience of people interested in enterprise architecture including practicing and aspiring architects, architecture managers, academic EA researchers, EA lecturers and students in universities.

At a moment when the nuclear nonproliferation regime is under duress, Rebecca Davis Gibbons provides a trenchant analysis of the international system that has, for more than fifty years, controlled the spread of these catastrophic weapons. The Hegemon's Tool Kit details how that regime works and how, disastrously, it might falter. In the early nuclear age, experts anticipated that all technologically-capable states would build these powerful devices. That did not happen. Widespread development of nuclear arms did not occur, in large part, because a global nuclear nonproliferation regime was created. By the late-1960s, the United States and the Soviet Union had drafted the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), and across decades the regime has expanded, with more agreements and more nations participating. As a result, in 2022, only nine states possess nuclear weapons. Why do most states in the international system adhere to the nuclear nonproliferation regime? The answer lies, Gibbons asserts, in decades of painstaking efforts undertaken by the US government. As the most powerful state during the nuclear age, the United States had many tools with which to persuade other states to join or otherwise support nonproliferation agreements. The waning of US global influence, Gibbons shows in The Hegemon's Tool Kit, is a key threat to the nonproliferation regime. So, too, is the deepening global divide over progress on nuclear disarmament. To date, the Chinese government is not taking significant steps to support the nuclear nonproliferation regime, and as a result, the regime may face a harmful leadership gap.
