Logic Model
A planning tool that links inputs, activities, outputs and outcomes in a simple visual chain.
Evaluation practice field / W.K. Kellogg Foundation resources
This page is a plain-English practice summary. It attributes the source field and avoids presenting the framework as Positively Devious intellectual property.
What this framework helps with
- clarifying programme components
- communicating with funders
- checking whether activities and outcomes line up
Three questions it helps teams ask
- What resources and activities are actually in scope?
- Which outputs are evidence of activity, not change?
- Which outcomes are realistic within the timeframe?
How to use it in youth and community work
Use Logic Model as a lens for better decisions, not as a script. Start with the local context, invite the people affected by the work into the interpretation, and turn the framework into practical questions, design choices and learning habits.
For Positively Devious, this framework matters because it helps explain one part of the wider conditions around positive deviance: the relationships, opportunities, skills, systems and power arrangements that make uncommon positive outcomes more likely to be noticed and learned from.
What to watch out for
- logic models can over-simplify complex change
- outputs are not outcomes
- the diagram should be updated as learning emerges
