Logic models have become a critical feature of program planning and evaluation. Using a logic model framework provides a visual summary that shows the relationship between the program’s resources, activities, outputs, and outcomes. The logic model is a tool that helps individuals see the interrelationships between the different components of a program. By using logic models, program planners and evaluators can more effectively examine a program’s theory and logic. The logic model tool highlights the program’s underlying theory, the service activities, and the organizational structure for accomplishing program outcomes. The process of developing a logic model assists developers and evaluators and other stakeholders in understanding a program’s assumptions and evaluating the logical links between what programs are doing and the outcomes they hope to achieve. Because of their utility logic, models have become widely used in social service programs.
