The decision-makers taken into account, usually work under time pressure with a lot of missing data. Most of the time the decision-makers are at a loss and have no references on which they could base their reasoning which leads them to a crisis we want to avoid in future cases. The main conclusions show the importance not only of feedback but also of reasoning by analogies. A first part gives briefly the theory on which this study is based. It describes the sample of decision-makers considered and the questionnaire and then gives the conclusions.
Several appendixes explain the main results based on econometrics.
This case-study is mostly a descriptive study and we are now checking if those results can also become prescriptive.
