Logic model
A logic model is a tool for showing what a program will do and achieve. At its most basic, a logic model has two components: what you plan to do and what will happen as a result. These two components can be further broken down to a linear chain from a program’s inputs (e.g., resources), to activities (e.g., programs), to outputs (e.g., public education), and finally outcomes (e.g., improved health).
A logic model is useful for:
Evaluation: Identify possible elements to be evaluated
Planning: Identify gaps that need to be addressed
Communication: Explain the purpose of a program to stakeholders
Management: Track and monitor operations
When done right, all components of a logic model will be specific and measurable, making it an important part of a program evaluation. Metrics can be assigned to components of the logic model to allow evaluators to track progress and/ or measure performance of the program.
Logic model quick reference
What you plan to do → What will happen
Inputs → Activities → Outputs → Outcomes
