The Enhanced Bayesian THERP (Technique for Human Reliability Analysis) method has been subject to evaluation within the framework of the “International HRA Empirical Study” using simulator data in order to better know its characteristics from a more international perspective. This paper gives an overview of the Enhanced Bayesian THERP method with major experiences from predictive analyses within the International HRA Empirical Study. Some possible reasons behind more or less successful predictions compared to experimental results will be elicited. Based on lessons learnt, strengths and potential weaknesses of the method will be discussed. Finally, a number of possible improvement areas have been identified for consideration in future development of the method.
