This document introduces logic modeling and its components. A logic model shows the resources, activities, outputs, and outcomes of a project. It displays the sequence of expected consequences of activities. Resources are inputs like staff, funding, and materials. Activities are actions taken, like workshops or volunteer patrols. Outputs are direct products, such as people served or newsletters distributed. Outcomes are changes resulting from activities, like increased literacy or reduced crime. Short-term outcomes occur directly after activities. Mid-term outcomes happen further in the future. The ultimate impact is the long-term change the project intends to make in the community or field. The document provides examples of logic models for a library program and neighborhood crime watch.
