The second approach, the scenarios approach, takes as its point of departure the assumption that, even with the understanding of evolution available to us today, it is still beyond the realm of the possible to understand sufficiently how systems develop, and to draft predictions.
This approach, which began to develop in Europe toward the end of the 1960s, maintains that the more the pace of change is accelerating, the less valid are the models we have at our disposal.
For this reason, the practitioners of this approach suggest the preparation of a number of possible and reasonable scenarios.
They suggest making a thorough analysis and formulation of those scenarios, together with the client organizations, in order to plan the procedures of the organizations' response in a way that will be most fitting for each scenario.
