The appreciation that a person makes of the situation depends mainly on the following four elements:
- the nature of the information available
- personal experience, which results in personalized mental models, and a library of configurations that the brain recognizes.
- the purpose of his current work: if the operator is focused on the resolution of an incident, he will be acutely aware of all the information that he is
expecting or looking for to manage this situation. It is possible, however, that he may miss information relating to the start of a second incident that is
independent of the first. - the interactions with the work group: in certain cases, interactions with other operators can make it possible to integrate information that had not
been identified and thus modify the appreciation of the situation. They can also sometimes play a part in blocking the whole team in an inappropriate
appreciation.
