Systems Thinking has become a key competence and can be considered as a way of thinking aimed at solving complex problems related to real-world uncertainty. It starts from thebasic principle that the world is a system
of highly interconnected natural, technical and social entities, hierarchically organized to produce behaviors observable by stakeholders. Inthis sense, Systems Thinking is a tool with which it is possible to describe a system as
a whole (in other words, by explicitly addressing the various interdependencies that are acting ina system and its non-linearities), highlighting its dynamic nature and the interactions that occur among the elements of the system
and avoiding any simplification and/or linearization(linear thinking has led decision makers to take linear decisions in a deeply non-linear world, hence producing huge disasters).
