Humankind progresses in proportion to its wisdom which has roots in practice, acquired skills, available data and information, concepts and knowledge. To be wise, humankind needs to be informed and knowledgeable; otherwise it will not survive its own failures. Progress in knowledge was painfully slow as long as the racial memory was transmitted only by oral tradition. With the invention of writing and books the process of knowledge discovery and dissemination has been accelerated. Today, computers and their networks speed up that process far beyond our imagination. In the 2000s the Information Wave significantly controls the Agricultural and Industrial Waves through millions of computers. IT supports decision-making based on knowledge-oriented systems such as data mining that, for example, discovers knowledge about customers, organizational dynamics, and so forth to achieve competitive advantage.
