The Logic Model is a simple and widespread form of illustrating a results model. It depicts how a project is to function in the form of a linear chain of cause and effect. The illustration does usually not include external factors.

Suitability
This model forms a good basis for monitoring and assessing the outcomes of simple projects in situations of low complexity.
| Advantages | Disadvantages |
| Simple illustration | Reduces cause and effect to a linear chain |
| Focus on the project’s core elements | Does not take account of external factors |
| Good basis for impact assessment | The process of change is not visible |
| Widely used | Risk of tunnel vision |
| N.B. Do not confuse ‘Logic Model’ with ‘Logframe’. The ‘Logic Model’ is an important part of the widely used Logical Framework Approach. It is the basis for the Logical Framework Matrix, known as ‘Logframe’, but ‘Logic Model’ should not be equated with ‘Logframe’. Firstly, a Logframe contains more information than a pure Logic Model and secondly, far more complex and not strictly linear results models should be used to produce a Logframe.
