Acknowledgments

This book would not have been possible without the efforts of many people. First and foremost, we would like to thank our friends at O'Reilly Media: Andrew Odewahn, Mike Hendrickson, and Andy Oram. They have provided us with invaluable guidance and support throughout the entire process. And special thanks to Mary O'Brien, for guiding us from the first draft to the completed version that you are holding.

We are indebted to our reviewers for the time and effort they put into helping this book be successful. Without them, this book would contain many factual and conceptual errors. So, thanks to:

• Scott Berkun

• Heather Day

• Gnaneshwar Dayanand

• Matt Doar

• Oleg Fishel

• Karl Fogel

• Tarun Ganguly

• Faisal Jawdat

• Sam Kass

• Marc Kellner

• Dave Murdock

• Jayne Oh

• Neil Potter

• DVS Raju

• Eric Renkey

• Rob Rothman

• Virginia Smith

• Lana Sze

• Chris Winters

We would also like to thank our friends at Carnegie Mellon University: Sandra Slaughter at the Tepper School of Business and Anthony Lattanza at the School of Computer Science, who helped us with our initial proposal.

And special thanks go to Lisa Kellner, without whom this would be a much more difficult book to read, and to Nisha Sondhe for taking the photographs that capture each chapter's main concepts (except for Chapter 7, which was taken by Steven Stellman. Thanks Dad!).

Andrew would like to thank Mark Stehlik, Catherine Copetas, Klaus Sutner, and Robert Harper at the CMU School of Computer Science. Jenny would like to thank Robert Horton, who exposed her to many of the ideas that later became the practices in this book. And we would both like to thank Jim Over, Tim Olson, and the rest of the folks from the Software Engineering Institute who have answered our questions over the years.

And finally, we would like to thank our families and friends for putting up with our incessant babble about all of the things you're about to read.

Good luck!
