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.

Modeling business behavior

Business behavior models show how your business performs things such as the following:

  • How services are provided
  • How requests are handled internally
  • What are the steps to be followed, and are they automated or not?
  • What resources are required to perform which behavior?

All these questions and more can be answered in architecture models that describe business behavior. This is what we will learn in this section, and we will cover these topics:

  • Defining business services
  • Defining business processes
  • Defining business functions
  • Defining business interactions
  • Defining business events

With that said, let's start with the first business behavior element – the business service.

Defining business services

"A business service represents explicitly defined behavior that a business role, business actor, or business collaboration exposes to its environment." (https://pubs.opengroup.org...
