Abstract We perform the opinión evolution analysis of a group of individuals under a decision-making situation. Firstly, we study the case of a constant global external source's action on the group whose individuals do not interact; considering different connectivity types be-tween the source and the group's members, namely, binary or continuous with constant or time-dependent intensities. Secondly, we analyze the case of a complex network featured interaction among individuals in addition to the action of the global source. After wards, we study the case in which there are the socalled inflexibles present in the group and whose main characteristic is that they are intransigent and opposed to changing their opinión thus, hindering consensus building. Finally, we address the situation in which there are only interactions between individuals, without considering the external source, this leads to a sensitivity towards the initial conditions of individual opinions for the evolution of the opinión state. In all cases, we analyze and compare the effects of the model variants on the group opinión, where the achievement or not of consensus is an essential aspect of the study.
