It is not correct to say that informal institutions do not play a role in the processing phases of systems theory. This is because the processing phases of this theory are based on building the limits and goals of a system that is natural or created by human beings. This is because the objectives and delimitation of a system are completely related to the creation of rules and concepts within the community in which this system is inserted. These rules and concepts, as well as the ideas and certainties of a community, are developed by non-formal institutions. In this case, we can say that informal institutions determine the basis for the limitation and goal creation of a system, which are the main elements of the processing phases of systems theory.
