Link: Different organizations think quite differently about the term ‘theory of change’. On this portal, ‘theory of change’ (ToC) refers to the understanding an organization, project, network or group of stakeholders has about how political, social, economic, and/or cultural change happens, and its contribution to such a change process. ToC thinking is, therefore, the process of developing that understanding and using it to reflect continually in ways that allow for adaptation and checking of assumptions.
