The banking world perplexed me through four challenges which hinder a more rigorous management of risks in information systems. I named them Ambiguity, Likelihood, Influence and Decision Problems. To solve them I engineered an approach employing scenario techniques, the convolution of signals, Rough Sets Theory and Utility Theory. The world of fire artists helped me in reenergi-zing myself from the strenuous writing process I engaged in. To travel between the above worlds, I mainly used public trains. In fact, considerable parts of this thesis evolved during weekends on my journeys between Zurich, Innsbruck and Merano. From the academic world I would like to thank Prof. Dr. Wolfgang Krger (referee) and the co-referees Prof. Dr. Hans-Jakob Lthi, Prof. Dr. Adrian Gheorghe and Prof. Dr. Solange Ghernaouti-Hlie who taught me academic rigor. I also thank my colleagues at the Laboratory for Safety Analysis of the Swiss Federal Institute of Technology in Zurich (ETHZ) namely, Monika Mortimer for her administrative support as well as Dr. Martin Diergardt and PhD candidate Manuel Kaegi for listening to and sound boarding my ideas. I would also like to mention Dr. Marco Laumanns of the Institute of Operations Research and Jrg Schelldorfer of the Seminar for Statistics of ETHZ for their invaluable support. Further, I would like to thank PhD candidates Markus Schlaepfer and Sigrid Wagner for two delightful evenings with an inspiring strategy game symptomatically called Risk!. I also thank Dr. Roman Bolinger, Dr. Nathalie Weiler and Dr. Gritta Wolf for reading the manuscript. From the banking world I would like to thank Adolf Doerig of Pukall Doerig + Partner, Dr. Helmut Kaufmann and Dr. Stephan Murer of Credit Suisse as well as Dr. Ralph Hol-bein of Ernst & Young for overlooking the development of the case study in the context of a global bank.
