Second, it explains inaccuracy in terms of optimism bias and strategic misrepresentation. Third, the theoretical basis is presented for a promising new method called "reference class forecasting", which achieves accuracy by basing forecasts on actual performance in a reference class of comparable projects and thereby bypassing both optimism bias and strategic misrepresentation. Fourth, the paper presents the first instance of practical reference class forecasting, which concerns cost forecasts for large transportation infrastructure projects. Finally, potentials for and barriers to reference class forecasting are assessed.

Dabei geht es hauptsächlich um die Modellierung der Verlustverteilung, die Grundlage für den "Verlustverteilungsansatz". Durch die Monte-Carlo-Simulation der Verlustverteilung ermitteln wir dann den Value-at-Risk (VaR), der das Eigenkapital für das Operationelle Risiko bestimmt.
