ACKNOWLEDGEMENTS

No book lives alone, as you already know.

Here are some people and organizations that have helped immensely along the way.

Thanks to Specific People ...

Ralph Hodgson has this amazing library of obscure and interesting books. More astounding, though, is how he manages to have in his briefcase just that obscure book I happen to need to read next: Vinoed's Sketches of Thought and Wenger and Lave's Situated Learning, among others. The interesting and obscure books you find in the References chapter probably came from Ralph's library.

Luke Hohmann tutored me about Karl Weick and Elliot Soloway, and Jim Highsmith, who taught me that "emergent behavior" is a characteristic of the rules and not just "lucky." Each spent a disproportionate amount of time influencing the sequencing of topics and accuracy of references, commenting on nearly every page.

Jason Yip beautifully skewered my first attempt to describe information dissemination as gas dispersion. He wrote, "Kim is passing information. Information is green gas. Kim is passing green gas..." Yikes! You can guess that those sentences changed!

Bo Leuf came up with the wonderful wordplay of argh-minutes (in lieu of erg-seconds) as the unit of measure for frustrating communications sessions. He also was kind enough to double-check some of my assertions. For example, he wrote to some Israelis to check my contention that in Israel, "politeness in conversation is considered more of an insult than a compliment." That produced an exciting e-mail exchange, which included (from Israelis): "Definitely wrong on this one, your author.… We always say hello and shake hands after not seeing for a few days.... I think your author is mistaking a very little tolerance for mistakes at work for a lack of politeness." Another wrote, "Regarding your being flamed. There is no way out of it, no matter what you say. According to me, Israelis would demand of you to have your own opinion and to stand behind it. And of course they have their own (at least one :-)." Benny Sadeh offered the word I finally used, "frankness."

Martin Fowler contributed the handy concept of "visibility" to the methodology discussion, in addition to helping with constructive comments and being very gentle where he thought something was terrible.

Other energetic reviewers I would like to recognize and thank (in first-name alphabetical order) are Alan Harriman, Allen Galleman, Andrea Branca, Andy Sen, Bill Caputo, Charles Herbaut, Charlie Toland, Chris Lopez, Debbie Utley, Glenn Vanderburg, James Hanrahan, Jeff Miller, Jeff Patton, Jesper Kornerup, Jim Sawyer, John Brewer, John Cook, Keith Damon, Laurence Archer, Michael Van Hilst, Nick Fortescue, Patrick Manion, Phil Goodwin, Richard Pfeiffer, Ron Holiday, Scott Jackson, Ted Young, Tom DeMarco, and Tracy Bialik.

The Silicon Valley Patterns Group took the trouble to dissect the draft as a group, for which I doubly thank them.

All these people did their best to see that I fixed the weak parts and kept the good parts. If I had had another few years to keep reworking the book, I might even have been able to get it to the point that they would have accepted it.

In the absence of those extra years, I thank them for their efforts and apologize for not being able to fix all the awkward spots.

Thank goodness the Beans amp; Brews coffee shop finally started playing jazz and rock again. I lost several months of writing to heavy metal and country music.
