摘要

As usual, professor Woodall has presented a stimulating and thought-provoking review paper. As a result of professor Woodall's extensive literature study, many actors from different camps are brought on stage presenting their lines. The groups on the stage are mainly quality gurus and representatives of the peer review literature. Walter Shewhart is allowed a single line in the drama, although we imagine that he is watching from the wings, and the attentive audience consists of 11,000 quality professionals who are members of the Statistics Division of ASQ.
