One need not be eminent in any part of profound knowledge in order to understand it and to apply it. The various segments of the system of profound knowledge cannot be separated. They interact with each other. For example knowledge about psychology is incomplete without knowledge of variation.
W. Edwards DemingIt is important that an aim never be defined in terms of activity or methods. It must always relate directly to how life is better for everyone. . . . The aim of the system must be clear to everyone in the system. The aim must include plans for the future. The aim is a value judgment.
