Abstract. Many case studies show that unstructured decision-making processes in teams are contributing factors to accidents. In situations without any preconfigured solutions, airlines have developed decision models. In our article, we give an overview and comparative analysis of different models. We discuss FOR-DEC, developed by Lufthansa and the German Aerospace Center. Findings from an explorative study on pilots’ experiences with FOR-DEC and from a workshop with pilots and experts from non-aviation high-risk domains are reported. The model is useful for structured decision-making in complex situations when there is enough time. Moreover, some extensions to FOR-DEC could be beneficial, for example, the integration of expert knowledge into the decision process and the explicit integration of the team in the decision-making process. Results give advice for the useful implementation, application, and training of decision-making tools using the example of FOR-DEC.
