Quantitative and qualitative data were collected from multiple sources including desk review, project site visits, and interviews with key stakeholders. Each category of data was analyzed using mainly descriptive statistics and a stakeholder feedback workshop was held in each of the seven countries to validate the collected data.
The evaluation found that the Bank’s interventions were relevant and achieved positive results, but had design weaknesses which led to outputs and outcomes being lower than expected. The projects were efficient economically, but suffered from implementation delays. Their benefits are somewhat likely to be sustained. The evaluation distilled five key lessons:
