Dedication

To my incredibly encouraging wife, Kirsten; my children, Nikolas, Dominick, and Treyton; my parents, Jerry and Faye Truskowski, for the obvious reasons; and my wife’s parents, Jack and Bonnie Barthel, who have never suggested (that I know of) that their daughter find a “non-writing” husband. All of whom prove that even to a Six Sigma practitioner, a special cause once in a while isn’t always bad.

To my family for their love, support, and patience. Special thanks and appreciation to my husband Craig, my son Kenny and daughter Laurie, and to my parents, Allen and Muriel Gove.
—Carolyn Pexton

To the many people who have and will die because their healthcare provider did not use the Six Sigma approaches.
—Dr. H. James Harrington

To my friends and family doctors, including Dr. Robert Weber, Vinod Motiyani, John Saran, Michael Koehne, Diane Metrick, John Saniat, Nandini Upadhayay, and Bob Manam.
