Evaluators and implementers develop Theories of Change (ToCs) to explain the logic of a proposed project, demonstrate how desired change could happen in a particular context, and provide data-driven rationales for how and why it will succeed in generating impact. ToCs are developed in the proposal phase or early in project implementation but are not returned to during the rest of the project. Yet, even the best-laid plans often go awry, and evaluators miss key opportunities to reflect on their approach. To promote equity and social justice in our work, it’s crucial to challenge our own epistemological foundations by identifying and testing our biases to consider the ramifications of our practice. One such way to do this is by iteratively and deliberately testing a ToC throughout the project lifecycle. By using a ToC not only as a product, but as a process, evaluators can reap a multitude of benefits such as: proactively identifying risks, triggering reflection and iterative learning, appropriately adapting work plans, strengthening communication, establishing (or maintaining) stakeholder buy-in, and facilitating proper hand-over.
