A logic model or program theory is a description or model frequently pictorial of how a program is supposed to achieve its expected outcomes and solve the identified problem for which it was created. It creates a logical links between expected outcomes and the activities designed to achieve them and incorporates the evidence-based theoretical assumptions that explain how the activities will lead to outcomes. A program theory or logic model is NOT the theoretical framework on which your project is based although it may be related to a theoretical framework. A theoretical or conceptual framework is a general theory that explains why some things happen. A program theory or logic model is unique to your project and explains how it is supposed to work.
