the number jam

摘要

Fact-based decision-making has been emphasised in all business improvement methodologies, but never as much as in recent six sigma practices. However, it need not be highbrow statistics, which deters beginners, contend the authors of this book. The authors have gone back to the basics of the Motorola practice by emphasising six sigma's nonstatistical intent as a philosophy for breakthrough improvement. The title is catchy and makes one first surmise that one is totally freed from data. However, 'virtually' is added in small letters to the title.
