Developing a Logic Model or Theory of Change

What is a Logic Model? A logic model presents a picture of how your effort or initiative is supposed to work. It explains why your strategy is a good solution to the problem at hand. Effective logic models make an explicit, often visual, statement about what activities will bring about change and what results you expect to see for the community and its people. Having a logic model keeps everyone moving in the same direction, providing a common language and a common point of reference.

When can a logic model be used? During planning During implementation During staff and stakeholder orientation During evaluation During advocacy

How do you create a logic model? 1.Find the logic in existing written materials to create your first draft. 2.Determine the appropriate scope of the model for its intended users and uses. Consider creating a family of models for multiple users. 3.Check whether the model makes sense and is complete. 4.Attend to the nuts and bolts of drawing the model. 5.Revisit and be ready to revise the model as necessary.

What makes a logic model effective? Logically links activities and effects Is visually engaging (simple, parsimonious) yet contains the appropriate degree of detail for the purpose (not too simple or too confusing) Provokes thought, triggers questions Includes forces known to influence the desired outcomes

What are the benefits and limitations of logic modeling?

Benefits Logic models… Integrate planning, implementation, and evaluation. Prevent mismatches between activities and effects. Leverage the power of partnerships. Enhance accountability by keeping stakeholders focused on outcomes. Help set priorities for allocating resources.

Benefits (cont.) Logic models… Reveal data needs and provide a framework for interpreting results. Enhance learning by integrating research findings and practice wisdom. Define a shared language and shared vision for community change.

Limitations First, no matter how logical it seems, there is always a danger that your model will not be correct. Establishing the appropriate boundaries of a logic model can be a difficult challenge. On a purely practical level, logic modeling can also be time consuming, requiring lots of energy in the beginning and continued attention throughout the life of an initiative.
