Enterprise Architecture at Work: Modelling, Communication and Analysis

An enterprise architecture tries to describe and control an organisation’s structure, processes, applications, systems and techniques in an integrated way. The unambiguous specification and description of components and their relationships in such an architecture requires a coherent architecture modelling language. Lankhorst and his co-authors present such an enterprise modelling language, ArchiMate, that captures the complexity of architectural domains and their relations and allows the construction of integrated enterprise architecture models. They provide architects with concrete instruments that improve their architectural practice. As this is not enough, they additionally present techniques and heuristics for communicating with all relevant stakeholders about these architectures. Since an architecture model is useful not only for providing insight into the current or future situation but can also be used to evaluate the transition from ‘as-is’ to ‘to-be’, the authors also describe analysis methods for assessing both the qualitative impact of changes to an architecture and the quantitative aspects of architectures, such as performance and cost issues. The modelling language and the other techniques presented have been proven in practice in many real-life case studies. So this book is an ideal companion for enterprise IT or business architects in industry as well as for computer or management science students studying the field of enterprise architecture.

Enterprise Architecture Planning: Developing a Blueprint for Data, Applications and Technology

More advanced than traditional system planning approaches, Enterprise Architecture Planning (EAP) outlines a stable business model independent of organizational boundaries, systems and procedures; defines data before applications; and allows data to determine the sequence for implementing application systems. This invaluable book offers a common-sense approach to EAP and includes numerous examples of architectures, procedures, checklists and useful guidelines. The book was described as a substantive contribution to the body of IS planning knowledge by John A. Zachman.

IT Architecture Toolkit

Enterprise IT architecture made practical — finally! There’s only one way to maximize legacy infrastructure while integrating new partners, technologies, applications, and data streams: begin with a coherent enterprise architecture. But most approaches to enterprise architecture have been far too complex and theoretical–until now. IT Architecture Toolkit is a breakthrough: a practical, simple, rapid, and complete approach to delivering on the promise of enterprise architecture. Jane Carbone’s approach has been proven in mid-market and Fortune 500 enterprises alike. Step by step, Carbone shows how to integrate business, architecture, implementation, and all key outputs: for data, applications, technology, and people. Whether you’re an IT leader, architect, planner, or analyst, you’ll learn how to create strong, auditable links with business drivers; model your architecture simply, easily, and quickly; translate your models to real, manageable projects; define the value proposition for architecture and establish realistic metrics; achieve buy-in throughout your organization; and manage the soft aspects of your architecture initiative, including processes, roles, responsibilities, and organizational structure. Carbone provides a soup to nuts collection of methods and examples. Using her exercises, you will construct a complete draft architecture for your own business: one that will handle change, opportunity, growth, mergers, downsizing, whatever comes your way.

The Enterprise Architecture IT Project: The Urbanisation Paradigm

The basis for an Enterprise Architecture IT project comes from the identification of the changes necessary to implement the enterprise or organisations strategy, and the growing information needs arising from this, which increases the demand for the development of the IT system. The development of an IT system can be carried out using an urbanisation approach i.e. building an IT system using the metaphor of a city. This concept is based on the fact that in constructing or reorganising information systems, the reconstruction and modernisation involves permanent elements, as are found in a city. Although relatively new, this approach has been successfully employed in a number of projects over the past few years. The practical approach given in this book allows enterprises or organisations trying to safeguard the efficiency of their IT system, while minimising costs and risk, to implement the theory and put it into practice.

Align IT: Business Impact Through IT

At last, here is a book that brings IT’s relationship with business to life, and enables you to implement strategy rather than develop it. Richard Wyatt-Haines helps you see the true potential of IT in delivering the growth and success to which you aspire. Whilst you may have seen the chapter headings before, you won’t have seen the topics approached in a manner that helps you understand the what, the why and the how, and then shows you what you have to do on the ground to deliver impact and success.

Enterprise Architectures and Digital Administration: Planning, Design, and Assessment

This is the first book that addresses all three main activities in improving business and technology decisions: the planning, design and assessment of enterprise architectures (EAs). Emphasis is on medium and large-size organizations in the private sector (such as banks, airlines and auto industries) and the public sector (such as federal agencies, local government organizations and military services in the Department of Defense). The book addresses the challenges faced by EA builders through an organized presentation of the issues and a step-by-step approach. The material is based on real-life EA project experience and lessons learned over a decade working in multiple-contractor, multiple-discipline teams, and multiple-agency environments.
