A logic model is a versatile and useful visual planning tool that can be used to tell the story of a research project or programme in diagram-format. Using concise, simple descriptions, a logic model helps plot a pathway to impact, and serves as a useful tool against which to evaluate project outcomes and impact. Increasingly, funding organisations require a logic model as part of grant proposals. This session draws upon best practice in logic modelling to introduce the concept. Using case studies and examples, we will illustrate the concepts embedded in a logic model.
