In a rapidly changing world, many decisions are taken in conditions of stress and tight time pressure. Often, the results are less than optimal. Against this background, the goal of DECIDE-IT was to create an innovative, easily used teaching methodology that improves learners' capabilities when they are forced to take decisions in conditions of stress. The project has taken methods originally designed to train personnel involved in the management of natural and industrial disasters, and adapted them for use in management training. DECIDE-IT’s educational strategy is experience-based, simulating stressful situations without exposing learners to the risks they might involve. To this end the product adopts a blended approach, mixing classical training with tutor-supervised virtual role-playing in an online 2D simulation environment.
