• What is the best time to create a theory of change? – During the program design – Before data collection – Before data analysis
Timing
www.3ieimpact.org Lindsey Novak
Closing Remarks
• Ultimate goal: Answer the “why?” question • Identifies assumptions and creates
testable hypotheses • Identifies areas of potential weakness in
the program • Can be created for new and existing
programs
