Defining Theories of Change

This report focuses on how theories of change can improve the effectiveness of peacebuilding interventions. A review of 19 peacebuilding projects in three conflict-affected countries found that the process of articulating and reviewing theories of change adds rigour and transparency, clarifies project logic, highlights assumptions that need to be tested, and helps identify appropriate participants and partners. However, the approach has limitations, including the difficulty of gathering theory-validating evidence.
