We owe thanks to a large number of people who con-
tributed, in one way or another, to the creation of this book.
We are grateful to Dean Kim Clark and the Division of
Research at the Harvard Business School, who funded much of
the research involved in this project. Similarly, we are indebt-
ed to Swarthmore College and its president, Al Bloom, for
support of Lee’s work on the project, especially for a leave
provided during the writing; we owe Swarthmore gratitude as
well for maintaining the rich intellectual environment that
planted the seeds of this project almost 20 years ago, when
Rob was a student in Lee’s classroom.
We offer thanks to many friends ...
