Another common tool of program design that can be employed by community-based program designers is the [[logic model]]. Logic models are a graphical depiction of the logical relationships between the resources, activities, outputs and outcomes of a program.<ref name="LM">{{Cite journal|url=https://www.cals.uidaho.edu/edcomm/pdf/CIS/CIS1097.pdf|title=The Logic Model for Program Planning and Evaluation|last=McCawley|first=Paul F.|date=n.d.|publisher=University of Idaho Extension}}</ref> The underlying purpose of constructing a logic model is to assess the "if-then" (causal) relationships between the elements of a program. Community-based program designers can employ logic models to ensure that program inputs (available community resources) will support the activities of the community-based program, and that the outputs (resulting from the activities) will lead to the program's desired outcomes.
