Crisis creates environment which potentially impedes rational making decision at strategic and tactical plan, within responding to crisis.Why does decision making during the crisis challenge?
When we are faced with a threat of survival, we can't see the forest just by looking at the trees. That explains the reason why we have a difficulty in making a rational decision.
When we are in crisis, the resource available with us will be scarce. So you have to make a critical decision by deploying the available resources there by to maximizer the profit for the organisation.
Insufficient info, time constraint and scarcity. As Rumsfeld would say: there are many unknown unknowns. Just look at crisis definitions, eg Rosenthal and Kouzmin.
Too much stress, fear and anxiety on the part of decision makers, who nevertheless have to take expeditious and assertive actions. And crises oftentimes evolve fast and engender a range of unexpected situations that completely fail routines.
Because the crisis makes the decision maker preoccupied with his idea in the best way to solve the crisis in a correct and satisfactory manner, and therefore we find it better to act in such cases.
During crises many people are in the flight or fight mode, so to say. This causes lots of anxiety and non-clarity of thinking thus making good decisions harder to make and think rationally.
During times of crisis (with a severe time constraint), any normal human's mind would be pre-occupied with a heavy adrenaline rush, hindering cognitive thinking, and decision-making process.
