Measuring attribution: a practical framework to select appropriate attribution methods

Measuring impact in private sector development programmes is important but also challenging. This paper provides an overview of the most common attribution methods, and offers guidance on how to select the most appropriate attribution method for the diversity of interventions and their context. The paper also documents how four programmes - ALCP in Georgia, MDF in East Timor, Propcom Mai-Karfi in Nigeria and Samarth-NMDP in Nepal - have selected and implemented four different attribution methods.
