Acknowledgments
It would be wonderful if I were smart enough to come up with the ideas
in this book on my own, but I’m not. So I have to rely on the kindness
and wisdom of others who share with me what they are doing with big
data. I am therefore grateful to all those individuals who shared their
experiences and insights with me. Every story in this book—and there
are many of them—has a generous individual behind it.
I am also grateful to my friends at SAS Institute, which has spon-
sored much of my research on analytics. Two of the studies they
sponsored are described in this book. Mike Bright is my primary
contact at SAS, and Scott VanValkenburg was my first connection
there. Both continue to be good friends and advisers after almost
a decade of collaboration. Others at SAS deserving thanks include
Ken Blank, Jim Davis, Carl Farrell, Jim Goodnight, Deb Orton,
Adele Sweetwood, and too many others to mention.
I did some of the research in this book with the help of the Inter-
national Institute for Analytics, which I cofounded with Jack Phillips.
Thanks to Jack, Katherine Busey, Sarah Gates, Callie Youssi, and
everyone else at IIA for their help.
I’ve been a senior adviser to Deloitte Analytics for several years
now; Jane Griffin was a great supporter and friend. Thanks also to
Forrest Danson, Wendy DeHoef, Kelly Nelson, Tim Phillipps, and Fred
Roffman—all Deloitte Analytics folks—for their continued support.
Marcus Shingles at Deloitte led a research project on big data in the

Grocery Manufacturers Association in which I participated, and some
of those ideas are undoubtedly in the book as well.
Finally, I began a research project on data discovery while writing
this book, and some of the research made it into the book before it was
completed. Teradata Aster supported that research, and I would like
to thank Tasso Argyros and Mary Gros for giving me access to their
customers and product capabilities.
I also work with a number of companies and organizations as an
adviser or affiliated researcher, and I learn a lot from all of them. They
include, in alphabetical order, First Analytics, MarketShare, Medi-
data Solutions, the MIT Center for Digital Business, Mu Sigma, Real
Impact, Signals Intelligence Group, and Via Science. I tell all of these
organizations that my primary goal in the relationship is to learn from
them, and they all have delivered on that request.
The other people who played important roles in making this book
a reality are at Harvard Business Review Press. Melinda Merino has
edited several of my books in the past, and she was in this case—as
always—a great pleasure to work with. I can’t remember for sure, but
I think writing this book was her idea. Certainly she had great sugges-
tions along the way for making it more compelling and e ngaging.
I have been remiss in past books in not thanking Julie Devoll, my
longtime publicist at the Press. Normally I don’t know who is going
to publicize the book when I write the acknowledgments, but Julie
assures me that I will get her expert and unflagging services on this
one. If anyone hears or reads about this book, it will probably be
thanks to Julie.
I love the jacket design for this book and my previous one with the
Press, and that’s due to the excellent work of Stephani Finks. Tracy
Williams led the marketing team for the book. Allison Peter ably and
smoothly handled the copyediting and artwork. Thanks also to Julia
Kirby, my old friend and frequent editor at Harvard Business Review,

for helping me clarify my thoughts on this topic in a couple of articles
I wrote for the magazine.
My wife, Jodi Davenport, urged me to write a book on big data long
before I actually got started. My sons, Hayes and Chase, have at least
some interest in the topic as well—Hayes in terms of the entertain-
ment industry, and Chase in terms of education. Thanks to all of them
for the advice.
I have written more books than I have family, and I am now faced
with rededicating books to family members. My mother-in-law, Helen
Kubik, was the dedicatee for my book Competing on Analytics. Not only
did she get more enjoyment out of the dedication than anyone else in
the role does, but the book also sold quite well. So Helen, this book is
dedicated to you. Work your magic again, please!
