Fundamentals of Enterprise Architecture Management
This textbook provides a comprehensive, holistic, scientifically precise, and practically relevant description of Enterprise Architecture Management (EAM). Based on state-of-the-art concepts, it also addresses current trends like disruptive digitization or agile methods. The book is structured in five chapters. The first chapter offers a comprehensive overview of EAM. It addresses questions like: what does EAM mean, what is the history of EAM, why do enterprises need EAM, what are its goals, and how is it related to digitalization? It also includes a short overview of essential EAM standards and literature. The second chapter provides an overview of Enterprise Architecture (EA). It starts with clarifying basic terminology and the difference between EA and EAM. It also gives a short summary of existing EA frameworks and methods for structuring the digital ecosystem into layers and views. The third chapter addresses the strategic and tactical context of the EAM capability in an enterprise. It defines essential terms and parameters in the context of enterprise strategy and tactics as well as the operative, organizational context of EAM. The fourth chapter specifies the detailed goals, processes, functions, artifacts, roles and tools of EAM, building the basis for an EAM process framework that provides a comprehensive overview of EAM processes and functions. Closing the circle, the last chapter describes how to evaluate EAM in an enterprise. It starts by laying out core terminology, like “metric” and “strategic performance measurement system” and ends with a framework that integrates the various measuring areas in the context of EA and EAM. This textbook focuses on two groups: First, EAM scholars, ie bachelor or master students of Business Information Systems, Business Administration or Computer Science. And second, EAM practitioners working in the field of IT strategy or EA who need a reliable, scientifically solid, and practically proven state-of-the-art description of essential EAM methods.
Enterprise Architecture Fundamentals
"The book is divided into five parts: parts I and II take a general perspective on enterprise, systems, and frameworks, parts III and IV are focused on technical aspects, and part V takes a prospective view on new challenges and technologies . Part one outlines the basics of enterprise architecture modeling: Enterprises' maps (or blueprints) and territories (environments, systems, processes) Modeling primer: objects and surrogates Modeling paradigm: environments and systems Part two explains the core ideas of EA as a discipline: Distinction between business and systems perspectives Benefits of frameworks to map architectures and the management of changes The Pagoda blueprint as a revised understanding of the Zachman framework Part three considers the all-inclusive representation of data (environments), information (systems), and knowledge (enterprise): Descriptive and prescriptive models Profiles, meta-models, and the benefits of ontologies Ontologies, Knowledge graphs, and the building of actionable maps of environments, organization, and systems. Decision-making processes and the seamless integration of systems and representations. Part four deals with engineering and the transformation of enterprise architectures: Taxonomy of requirements and the distinction between architecture-oriented and business-driven requirements. Refactoring of requirements along enterprise architecture concerns, with a focus on digital transformation. Role of Use cases for the definition of business objectives, user-driven applications, and systems-oriented functions. Role of Model-based systems engineering (MBSE) at the hub of enterprise architecture transformations, between Agile developments and systems modernization. Part five considers enterprises as viable organisms and the consequences of new technologies for their resilience and evolution: Enterprises' capacity to change in terms of architecture versatility and plasticity, and the benefits of a revisited Capacity maturity model integration (CMMI) Evolutionary impact of Artificial intelligence and Machine-learning technologies with regard to enterprises' resilience in the face of disruptive changes in environments"--
Enterprise Architecture as Strategy
Enterprise architecture defines a firm's needs for standardized tasks, job roles, systems, infrastructure, and data in core business processes. This book explains enterprise architecture's vital role in enabling - or constraining - the execution of business strategy. It provides frameworks, case examples, and more.
