I dedicate this book to my family,

who provide a perpetual source of support and joy,

and to the students in my university and executive classes.

I dedicate this book to Jan, Jenny, and Christine

for supporting this effort, so much of which came

from time that otherwise would have been theirs,

and to the consultants at Personnel Decisions International,

who welcomed me into their field and

taught me a great deal along the way.
