This is an experiment designed to illustrate a stable system and the consequences of various forms of tampering which not only fail to improve anything but add instability and degraded performance. The experiment shows how management, depending on intuition and common sense, can make things worse. Deming discusses the nature of variation and its influence on any system or process. This volume also discusses the meaning of profound knowledge, which includes understanding of variation.
