The Initiative for System Dynamics in the Public Sector contracts with state agencies, local governments, the federal government and nonprofits to develop training and formal simulation models to address critical problems. Description - The Initiative has developed formal simulation models for the NYS Department of Mental Health, the Division of Disability Determinations, the Governor's Traffic Safety Committee, and the National Institute of Justice over the last couple of years. These projects provided the agencies with insights about key problems and allowed them to test different policies in a simulated environment to determine likely future outcomes. The Initiative has also provided systems thinking training to managers in NYS Department of Environmental Conservation, the NYS Office of the Comptroller, NYS Department of Education and the Lake Placid Town Board. The training goal is to provide participants with a set of tools for framing persistent problems.
