A logic model is a graphic representation to describe a program that shows the linkages between what the program does (the input and outputs) and the expected results (outcomes) related to a specific problem or situation. The model identifies the following elements related to the problem or situation:
- Inputs: What are the resources, contributions, investments that go into the program?
- Outputs: What are the activities, services, events, and products that reach people who participate or who are targeted?
- Outcomes/Impacts: What are the desired results or changes for individuals, groups, communities, organizations, communities, or systems?
- Assumptions: What are the beliefs we have about the program, the people involved, and the context and the way we think the program will work?
- External factors: What is the environment in which the program exists, including a variety of external factors that interact with and influence the program action?
Building the logic model begins by identifying the situation or problem to be addressed; for example, looking at the needs and assets; symptoms versus problems; the level of stakeholder involvement; the intended outcomes.
A typical logical model template:
