“…[F]or anyone interested in the wide, wide field of improvement and its related sciences, no other book offers more discipline and wit wrapped into a single, enjoyable package.”

–From the Foreword
by Dr. Donald Berwick

“For the novice, no single book on improvement offers a more complete and accessible summary.  For the intermediate, no other source is more likely to resolve areas of chronic confusion, such as in statistics or the psychology of motivation.  For the master, no overview will have a longer shelf life in offering great examples pithy vignettes, or linkages among topics to draw upon for both personal learning and resources for teaching others.”
