“… Uncertainty: there may be multiple or vague sources of information, and the information may be lacking or ambiguous (Crichton, 2001;Lagadec, 2012;Pearson & Clair, 1998) or massive and contradictory (Yammarino et al, 2010). However, the confusion reigning requires a rapid response based on a decision that must be taken fast (Sayegh et al, 2004), Urgency: whether the 'kinetics' are slow or fast, decision-makers must react very quickly and with major time pressure (Crichton, 2001;Hannah et al, 2009;Lagadec, 1991;Pearson & Clear, 1998), Significant short-term losses: Minimising these losses is the principal objective of crisis management (1997; Pearson & Clear, 1998), A loss of control of the situation: events spin out of control, and reality falls apart (Heiderich, 2010) High levels of stress (Crichton, 2001;Crocq et al, 2009;Kowalski-Trakofler & Vaught, 2003) Developing a tool to assess trainees during crisis management training for major risks ABSTRACT: Often based on simulation exercises, crisis management training helps prepare decision-makers to manage crises better.…”
