Systems thinking tools to help people analyze the extended consequences of different strategies or policies. At Loops, we use both qualitative and quantitative system dynamics. Qualitative system dynamics involves drawing causal diagrams that show the different cause and effect relationships that are assumed to give rise to a certain issue or phenomenon being studied. These diagrams can sometimes provide sufficient insight for analysis and for deciding on a course of action. We work with government and NGOs to garner insights through system dynamics analyses of complex social issues. Issues such as housing, healthcare, the energy system and national security are increasingly being recognised as in need of a systems perspective, and we believe that system dynamics is one of the most effective methods for delivering that perspective.
