The Institute of Systems Engineering mainly conducts qualitative research, such as developing models of the functioning of "human-centered" systems, such as families, schools, hospitals, and societies, which are composed of people and carry out specific purposeful activities, and analyzing and diagnosing the rules and regulations that regulate their activities. It also works to develop definitions of terms that are used in everyday communication, but that can be interpreted differently by each person from their own perspective, thereby creating conflicts.
