In general, the basic evaluative questions address the issue of what results the Bank has achieved with its interventions in a given country, sector, thematic area or project. This entails first assessing the evaluability of the Banks approach (i.e., strategy or project), then the Banks diagnosis of the problem, its intent with regard to possible solutions (expected results), the efficiency and effectiveness of Bank interventions, and the intended and unintended outcomes. In other words, did the Bank do the right thing? Did it do it efficiently and effectively? What happened as a result of the Banks actions? Because evaluation is a tool and all tools must be scrutinized constantly for improvement, OVE continuously reviews its methodologies. The methodological working papers included here should be viewed along with the methodological statements in the different types of evaluation reports for a better understanding of the approaches OVE has taken.
