Many stakeholders within and outside the company can be identified, ranging from top-level management to software engineers. Each stakeholder requires specific information presented in an accessible way, to deal with the impact of such wide-ranging developments. To predict the effects of such developments and modifications of an organisation’s business and IT, it is necessary but very difficult to obtain an overview of these changes and their impact on each other, and to provide both decision makers and engineers implementing the changes with the information they need.
This book is about enterprise architecture, the practice that tries to describe and control an organisation’s structure, processes, applications, systems, and technology in such an integrated way. More specifically, we focus on methods and techniques for making and using integrated descriptions by means of architecture models, visualisation of these models for various stakeholders, and analysis of the impact of changes.
