Advances in database management systems and networking will also incorporate methods for dealing with random inputs. Now that the reader is convinced, I hope, of the ubiquity of uncertainty in management and information technology, he will want to know just how much of this arcane mathematical knowledge he must acquire to be more effective in his job. If he knows how to assign probabilities to events, when to add them, and when to multiply them he is already in pretty good shape. If, and most importantly, he knows and really understands Bayes' Theorem, then he has a formal mechanism for learning about the world. He is already coherent.
Uncertainty is everywhere, but the tools to cope with it exist.
The important thing is to recognize that at least this first step is needed.
