2. Being the decider
Nothing is more difficult, and therefore more precious, than to be able to decide according to Napoleon
Bonaparte. (Larouse du XX- 1929). Sfez (1988) proposes a classification of decision maker evolution in three
stages:
the certain man is an actor of the classical organization making decisions in a rational manner, according to a
linear process in a certain universe; he can optimize all the factors and his individual objectives converge with
those of the entity;
the probable man is an actor with limited rationality seeking only a satisfactory solution in a more uncertain
universe but probabilistic;
the random man is an actor in current businesses where imprecision, uncertainty and complexity are very present;
decisions involve compromises.
Whatever the status of decision maker, there are several theories seeking to explain the decision-making process
based on different aspects.
