Logic model

The logic model is used during the developmental stages of program planning to demonstrate the logical flow of program elements. It provides a visual map of the activities and outputs of a health based program.

The logic model elements are defined below:

Inputs: the resources, contributions and investments that go into the program.

Outputs: the activities, services, events and products that reach the target audience.

Outcomes: the results or changes for individuals, groups, communities, organisations or systems.

Assumptions: the beliefs we have about the program, the people involved, the context and the way we think the program will work.

External Factors: the environment in which the program exists that includes a variety of external factors that interact with and influence the program.

Further information on what a logic model is and how to use it is available in section two of the SiREN SHBBV Program Planning Toolkit, in the Community Toolbox website, or provided by the University of Idaho.
