The Theory of Change underpins an organization's Impact Model, which helps demonstrate and communicate impact. It describes how and why a particular intervention is expected to lead to desired long-term impacts. In practice, this theory is often expressed through two key tools: the Problem Tree analysis and the Logic Model.
 

The Problem Tree analysis serves as the diagnostic component. It visually maps out the central problem, breaking it down into its root causes and effects. By doing so, it identifies where the organization’s interventions can be most effective. This detailed mapping helps clarify the underlying issues that need to be addressed, forming the starting point of the Theory of Change.

Building on the problem’s causes and sub-causes, the Logic Model translates the Theory of Change into a structured pathway, explaining the sequence from inputs and activities to outputs, outcomes, and ultimately the impact. The Logic Model not only shows the “if-then” relationships (i.e., if we invest in certain activities, then we expect specific outputs and outcomes) but also incorporates the assumptions behind these linkages. The Logic Model makes the Theory of Change tangible, measurable, and open to monitoring and evaluation.​
