The “Stuart Robbins philosophy” of IT project management is rooted in a genuine appreciation of the human side of technology. This book articulates these important and surpris- ingly simple (yet all too often overlooked) lessons. The accessible story- telling format will communicate to a wider audience than just IT management.” Maggie Law, User Interface Designer, PeopleSoft “I was thrilled to read this. It’s such an easy thing but most often it is overlooked. It’s very true that system reflects the harmony (or the lack of) of an organization. This book explains in plain English one of the se- crets of measuring the success or failures in this complicated and ever changing world of IT.” Ruyben Seth, Database Manager, Symantec Corporation (Oregon) “This is a very complicated and challenging concept and you have raised some serious thought provoking issues.” Atefeh Riazi, Worldwide CIO, Ogilvy & Mather, Inc. “These stories are easy to read, and good fodder for students!” Carol Brown, Ph.D., Kellogg School of Business “You are an excellent writer and [this theory] demonstrates that you are a visionary in our industry!” Steve Yatko, Head of IT R&D, Credit Suisse First Boston (NYC) 01_790109 ffirs.qxp 6/13/06 8:48 PM Page iii Lessons in Grid Computing: The System Is a Mirror Stuart Robbins 01_790109 ffirs.qxp 6/13/06 8:48 PM Page iv This book is printed on acid-free paper. ∞ Copyright © 2006 by John Wiley & Sons, Inc.

Before 1978, however, I was an English professor who taught writing and literature at a liberal arts college. What a delight for me, therefore, to encounter a business book that lives at the intersection of my two careers. This book is an experiment in discourse. It uses the medium of the story to engage the issues and ideas of business. Unlike other such experiments, such as The Goal, this book is profoundly intellectual in the very best sense of the term. And it needs to be, for it is tackling a deep idea, the no- tion that our computer systems replicate our social relationships and that managing either can be improved by learning from the other. The notion that computer and social systems are ecologically inter- twined is at first startling, but within seconds it becomes commonplace. Of course they are intertwined—how could they not be? But then why have we not made more of this in the past? Well, that is what bright ideas are all about: they show us things we are pretty sure we already knew but have never brought properly into focus. The stories Stuart tells are compelling in their own right. He is a good writer, and it shows. The book is a good read even if you don’t care a fig for business or technology. But if you do, it is an even better read, xi 03_790109 flast.qxp 6/13/06 8:49 PM Page xii xii Foreword provided you are willing to play your part. This book is not a how-to book. There are no 22 immutable laws of anything here nor any one- minute solutions to your daily problems, though there are lessons to be learned, and techniques that can be applied. This is a book that requires and inspires reflection. Reflection is largely missing in action in today’s business climate. At a time when the fundamentals of technology architecture and business process management are being revolutionized by the Internet and global commerce, we are far too focused on short-term transactional issues. At the opening of the 21st century, the economic torch is passing across the Pacific just as it passed over the Atlantic in the 20th century and the English Chan- nel in the 19th.
