Acknowledgments
This book has been 10 years in the making, so there are a lot of people
to thank. Because we may not remember them all, apologies to everyone
we missed.
First, we thank our participants, the sysadmins and others who let us
in to watch their activities and to talk about their jobs. Though we can-
not name them, we are certainly indebted to them. We hope they fi nd
this book useful. It is for them, after all.
Second, we thank those who worked with us to collect and analyze
data and to explore our conclusions through implementation, including
Rob Barrett, Chris Campbell, Mike Chavoustie, Allen Cypher, Andrew
Eberbach, Stephen Farrell, Peter Khooshabeh, Trevor Montgomery, Adam
November, Madhu Prabaker, Joe Ryan, Suchi Saria, Leila Takayama, Josh
Woods, Anna Zacchi, and Haixia Zhao.
Third, we thank those who supported the work over the years,
including our managers, our funders, and others: Kathryn Britton, Jarir
Chaar, Josephine Cheng, Steve Cousins, Mark Dean, Alan Ganek, Laura
Haas, Anant Jhingran, Jeff Kephart, Robert Morris, Stefan Nusser, Dan
Russell, Dan Shiff man, Barton Smith, Alfred Spector, Jim Spohrer, Ric
Telford, Steve White, and Michelle Zhou.
Fourth, we thank those who read and gave comments on early
drafts of this book and its parts, including Laura Anderson, Jim Barlow,

Dray, Steve Greenspan, Laura Haas, Tom Limoncelli, Tom Moran, B. J.
Scheid, and Ashish Sharma.
Fifth, we thank Oxford University Press, particularly Catharine
Carlin and Joan Bossert, our editors, Jennifer Milton, who shepherded
us through the production process, and Alex Kirlik, editor of the
Human-Technology Interaction series, whose encouragement and subtle
help over the last four years made this work possible.
Sixth, parts of chapters 2 and 3 were previously published in
“Collaboration in System Administration” by Eben Haber, Eser Kandogan,
and Paul Maglio in ACM Queue, volume 8, issue 12, December, 2010
(copyright the Association for Computing Machinery). It is reprinted
here with permission.
Finally, we thank our families, who patiently supported us while we
were not fi nishing this for so long. Thank you Elif and Eren Kandogan;
Teenie Matlock; Sheri and Talia Byrne-Haber; Julie, Olivia, and Anika
Bailey.
Prologue: Why We Wrote This Book
On a fall day in 2001, an executive took the stage in the auditorium at
the Almaden Research Center to tell us about a bold new IBM initiative
called autonomic computing. It was about how computer systems would
soon be able to manage themselves using many of the same principles
that an animal’s autonomic nervous system uses to manage its bodily
processes, whether breathing, beating, or repairing. It was a fascinating
vision, and it was important because information technology (IT) cus-
tomers were spending more money managing systems than they were
spending buying the systems in the fi rst place—and self-managing sys-
tems were expected to have lower total cost of ownership. This would
be a win for IBM, with better diff erentiated technology, and it would be
a win for customers, with lower costs in the long run.
As laid out at the time, autonomic computing aimed to make IT
more self-managing, particularly, self-confi guring, self-healing, self-
optimizing, and self-protecting (see Kephart & Chess, 2003). It aimed
to replace much of what was usually done by the people who man-
aged IT systems with automation. So it was only natural when someone
stood up at that presentation and asked, “Do you know what the people
who manage systems actually spend their time doing?” The answer sur-
prised us: no. IBM did not really know, and there was no literature on it
