This tip sheet and template provides a detailed explanation of what logic models are and how they are important supports for the implementation, planning, and evaluation of programs; it provides logic model templates for individuals to use; and lists further information resources on completing a logic model.
Logic models are visual tools or representations that demonstrate how a program works. Logic models can reflect specific programs in specific communities, one program implemented in multiple communities, or a combination of programs implemented in a specific geographic area to achieve a shared goal. This document explains what a logic model is, why they are good for planning, communicating about, or implementing a program; and how to create a logic model. The process for developing a logic model is described as involving six steps: identify the project goal; identify the inputs; define the activities; specify the outputs; determine the desired outcomes; and review and refine the draft logic model. The document also provides guiding questions for how to write strong statements that will help program developers to formulate a comprehensive and well-thought-out plan for the program. Those guiding questions address the following issues: program goal; inputs, such as resources needed to implement the program; activities, or the actions taken to achieve the desired outcomes and goals of the program; outputs, that is, the direct products or services resulting from the activities; outcomes; and external factors, which may influence or be influenced by the program, and can affect its implementation, program recipients, staffing, and resource availability. The document provides two logic model templates, and links to additional resources.
