Book excerpt: Critique W. Edwards Deming's work at your peril. After all, he probably set whatever standard you're using. This volume - revised by the author before his death in 1993 and partially based on his 1950s work with the Japanese - may strike the contemporary reader as a curious mixture of seminal process thinking and idiosyncratic ruminations on education. Portions read like an artifact of the early 1990s, but in this regard, however, his volume offers a unique perspective on a turning point in American economic history: the shift to the knowledge-based economy. Deming's volume is suited to any serious student of management thought, and all human resources professionals should familiarize themselves with his work, which set the foundations for many of the transformations now underway in the corporate world.
