THEORY OF CHANGE (TOC)
Carol Weiss popularized the term “Theory of Change” as a way to describe the set of assumptions that explain both the mini-steps that lead to the long-term goal and the connections between program activities and outcomes that occur at each step of the way. It is a description of why a particular way of working will be effective, showing how change happens in the short, medium and long term to achieve the intended impact. It can be represented in a visual diagram, as a narrative, or both. Theory of Change defines long-term goals and then maps backward to identify necessary preconditions.
