When you're in an environment under pressure you make decisions quickly. This is the speed that characterizes this type of decision. How can we quickly take the right decision, is to decide under pressure.
The big difficulty in making a quick decision is that one is tempted to consider the issue with his own eyes. Everyone has been shaped by his upbringing, his culture and environment. Each brain reads the reality in a way and sort information in a unique way. We should therefore be particularly vigilant regarding the cultural filter.
In a second time to force them to acquire an overview of the problem, we will of course go to find information on the Internet, whose speed makes it a vital tool, but also look to our peers and to experts: consult experts can clarify the issue of limiting the scope of questioning. The principle: they have already faced similar problems. If this is not too complicated, benefit from their experience can save valuable time when we are in a hurry.
In any case, if we have two solutions, we must find the third. Otherwise there is a risk to limitate an early decision to evidence.
