In risk management literature, a great number of methods can be found that are suitable for risk assessment. Most of them can only be used if there are historical data available as they rely on statistical analysis to assess risks. However, many times there is no daily database to use for assessing most risks. The question is 'Exactly how to assess the risks in latter case? To answer this question the author has developed a method that has been used in more than 50 different applications up to now. The aim of this book is to demonstrate the way how can be assessed the risks step by step in order to support management decisions at strategic, project or at operational level. Four case studies illustrate how to assess and treat risks using the method worked out by the author. The book can be useful for all, who are interested in teaching or applying integrated risk assessment but especially for top managers, risk masters and practitioners, project managers, economists and internal auditors.
