Overview

This book defines the Enterprise Unified ProcessTM (EUP), which was first introduced by myself in 1999 and later enhanced to support a wider variety of clients. The EUP is an extension to the industry standard IBM Rational Unified Process (RUP). Both the EUP and RUP are instantiations of the Unified Process (UP). The UP, also known as the Unified Method or the Unified Software Development Process (USDP), was originally a framework from which system processes were to be instantiated. A system process defines the roles that people fulfill, the activities that they perform, and the artifacts that they create to develop, operate, and support one or more computer systems. Over the years the primary focus of IBM Rational has been evolving the RUP.

Whereas the RUP defines a software development lifecycle, the EUP extends it to cover the entire information technology (IT) lifecycle. The EUP extends the RUP to include the operation and support of a system after it is in production and its eventual retirement. Furthermore, because all but the smallest organizations have more than one system, the EUP also handles cross-system enterprise issues such as portfolio management, enterprise architecture, and strategic reuse. Although the RUP defines a very good software development lifecycle, it is only a start: you need the EUP to address the entire IT lifecycle and to provide a mechanism for true IT governance of RUP projects.

Features of This Book

One of the first things that you'll notice about this book is that we present a slightly different approach to the Unified Process. We don't work for IBM Rational, and as a result, we're in a position to objectively describe what actually works in practice. Don't worry, within the scope of the RUP, we don't deviate all that much because frankly IBM Rational has done a pretty good job within their chosen area. The value in this book is the extensions to the RUP -- two new phases and eight new disciplines -- making the RUP truly ready for real-world IT departments. Just take a quick look at the table of contents to see what we mean.

The bottom line is that this book looks at process from the viewpoint of an entire IT department, not just a single project or system, discussing the difficult issues that IT professionals face every day. The book features a wide range of figures that illustrate what you need to do. The text describes the issues you'll face and strategies for overcoming them, but it doesn't waste your time with minute details. In every organization where we've worked, we discovered that they had good people who knew what they were doing, but what was missing was a unifying vision for getting them to work together effectively. This book won't turn you into an expert portfolio manager, enterprise architect, or whatever, but it will explain the fundamental issues and strategies that these roles address within your IT organization.

This book has several features that will make it a valuable resource for you:

 


Who Should Read This Book?

This book is written for IT professionals who are experienced at the Unified Process, or at least an iterative and incremental development process, who want to improve and extend their approach to IT. You're competent at your job, but you realize that your organization, and perhaps you as well, need to change your approach to IT if you're going to succeed in the coming years. This book will provide the insights you need to identify where you're going wrong and will provide strategies for addressing those challenges.
