The planetary magnitude and depth of the economic meltdown hints eloquently that conventional methods of risk assessment, quantification, management and rating need to be reviewed seriously. In an increasingly turbulent and globalized economy a new look at uncertainty is mandatory as traditional approaches have been designed for a less severe and chaotic context. The book introduces a radically innovative approach to uncertainty management and illustrates how complexity management assumes a modern form of risk management which is particularly suited for a highly uncertain and turbulent economy. Innovative complexitybased rating schemes, such as on-line self-rating or holistic rating are introduced. The book advocates that thanks to objective and verifiable ratings, which are accessible to even the smallest of companies, it is possible to contribute to a more stable economy.
