Dedication

Whatever may be the limitations which trammel inquiry elsewhere, we believe that the great state University of Wisconsin should ever encourage that continual and fearless sifting and winnowing by which alone the truth can be found.

We dedicate this book to the citizens of Wisconsin for their vision of providing access to world-class education, and for their continued support of the University of Wisconsin-Madison; without them, this text would not exist. We also dedicate this book to our students who teach and challenge us—and then go forward to make the world a better place. Finally, with warm-hearted encouragement, we dedicate this book to the perplexed project manager who seeks to differentiate symptoms from issues in search of the true root cause.
