Practical Model-Driven Enterprise Architecture

By: Mudar Bahri, Joe Williams

Overview of this book

Most organizations face challenges in defining and achieving evolved enterprise architecture practices, which can be a very lengthy process even if implemented correctly. Developers, for example, can build better solutions only if they receive the necessary design information from architects, and decision-makers can make appropriate changes within the organization only if they know the implications of doing so. The book starts by addressing the problems faced by enterprise architecture practitioners and provides solutions based on an agile approach to enterprise architecture, using ArchiMate® 3.1 as an industry standard and Sparx EA as the modeling tool. You'll learn with the help of a fictional organization that has three business units, each expecting something different from you as the enterprise architect. You'll build the practice, satisfy the different requirements of each business unit, and share the knowledge with others so they can follow your steps. Toward the end, you'll learn how to put the diagrams and the content that you have developed into documents, presentations, and web pages that can be published and shared with any stakeholder. By the end of this book, you'll be able to build a functional enterprise architecture practice that supports every part of your organization. You'll also have developed the necessary skills to populate your enterprise architecture repository with references and artifacts.

IT expenditures are categorized into two main categories: Capital Expenses (CapEx) and Operational Expenses (OpEx). CapEx are the expenses on the purchase and acquisition of new assets such as new hardware, software, or owned facilities. OpEx on the other hand are the periodical and continuous expenses that occur as a result of operating IT resources such as human resource salaries, subscription-based software and infrastructure, utility bills, rented facilities, and other similar types of expenses.

This example has been chosen to illustrate a simple example of changes that can occur at the technology layer, which in your case could be a cloud migration project, an upgrade to the existing technology stack, or the shutting down of an...
