A global community connected through systems theory, science, and practice
"To gain knowledge, we must learn to ask the right questions; and to get answers, we must act, not wait for answers to occur to us."
ISSS Past President Anatol Rapoport
The ISSS is a community of researchers, learners, and practitioners who are devoted to transdisciplinary inquiry into the nature of complex systems and the application of systems approaches for transformative change.
Conceived in 1954, the ISSS advances systems science theory and application by connecting and enabling researchers and practitioners, and disseminates the knowledge of systems to a global audience.

Systems Outreach Engagements
This page is under development so please check back regularly for updated information on ways you can participate in outreach.
Click here for a Miro Board of systems organizations that we have connected with.
ISSS members are engaged in a number of activities around the world. Read more at https://www.isss.org/activities/
Many member activities are collaborative in nature and also involve partnerships and collaborations with other organizations:
American Association for the Advancement of Science (AAAS)
International Council on Systems Engineering (INCOSE) Systems Science Working Group
Systems Literacy
Systemic Action at the Village Level to encourage and support sustainable development.
World of Systems
The ISSS is one of the oldest organizations dedicated to the study, development and application of systems science, systems thinking, cybernetics and complexity science.
We are assembling lists of organizations, social network pages and groups, and also maps of the evolution of the field of systems and cybernetics. Here are some examples

Members of ISSS are researching and applying Systems Science in a variety of situations and circumstances. we are creating a temporary Editorial Board to decide what new research and application by ISSS Members to feature here. For more information please email webadmin@isss.org
AAAS Affiliate
In 1954 the founders of the current ISSS met at meetings of the American Association for the Advancement of Science (AAAS). They decided to start the Society for General Systems Theory later renamed Society for General Systems Research and now called the International Society for the Systems Sciences. One of the early group of founders and first presidents of our society in 1957, Kenneth Ewart Boulding was President of AAAS in 1980
