Interview
Key Informant Attribution
Evaluators interview key informants, such as team members or users, to assess whether they attribute specific outcomes to the product or initiative, the degree of that attribution, and the reasons behind it. The method relies on structured questioning to test the underlying causal theory against the perspectives of those directly involved or affected.
