Community-Based System Dynamics (CBSD) is a participatory method for engaging and working with communities and organizations to address complex issues. Developed from group model building and system dynamics, CBSD is now being used around the world, both in research and practice, to engage diverse communities and organizations. This 5-day course provides an introduction to CBSD, with opportunities for participants to receive feedback on preliminary designs for their own CBSD work. Participants will build capabilities relevant to CBSD, including qualitative causal mapping skills, exposure to system dynamics simulation models, skills on identifying issues appropriate for CBSD, assessing community readiness, convening a core modeling team, workshop design and facilitation.
