Archimedes, one of the earliest systems thinkers, famously promised, “give me a lever long enough, and a fulcrum on which to place it, and I shall move the world.” In their passion for change, leaders and changemakers are constantly searching for that long lever and leverage point, deeply aware that addressing system complexity often marks the difference between success and failure. We may be searching for creative leverage points that yield new results within existing systems, or we may be engaged in ambitious efforts to re-engineer entire systems. Our work with systems often relies only on our intuition, a capacity that tends to fail more frequently in the face of mounting complexity. The rigorous study of systems promises to bring critical system elements into strategic sharp relief, thereby offering the potential for breakthrough strategies and innovations. This workshop will introduce the theory and practice of Systems Thinking, helping participants explore its relevance to changemaking. Participants will practice using its tools applied to current work settings and ongoing projects. The specific tools and concepts considered will include stocks, flows, links, and balancing and reinforcing dynamics. The long lever and its mysterious fulcrum await you. Take hold and move the world.
