Why Use a Logic Model for Evaluation?
There are four primary ways a logic model can help you as you work on your evaluation:
- It articulates the "logic" behind how the program's activities lead to the desired change. Laying this out visually helps you test your assumptions—i.e., can you logically say that these activities will result in these outcomes?
- As you begin conversations with your stakeholders, it helps everyone to be on the same page about what you are trying to accomplish and how you're going to get there.
- It allows you to visually display progress toward your long-term goals. Presumably, the short-term outcomes will result in the intermediate outcomes, which ultimately contribute to the long-term outcomes. You may not be able to measure the long-term outcomes for awhile, but by measuring short-term and intermediate outcomes, you are able to demonstrate progress.
- It helps you focus the evaluation design—it helps identify the elements of the program that are most important to evaluate and the questions the evaluation will answer.
