Thematic Evaluation of ADB’s NSO Additionality (2008–2020)

ONGOING EVALUATION. This paper sets out the approach and methodology for the evaluation of Asian Development Bank’s additionality in its nonsovereign operations (NSO). Additionality more specifically refers to ADB’s set of inputs or services that help lead to unique value addition, ultimately leading to anticipated development results. The evaluation will analyze the additionality of ADB’s NSO and review ADB’s strategies, programs of assistance and their outcomes. The Independent Evaluation Department (IED) will undertake an examination of ADB's additionality in NSO covering the period 2008–2020.

The evaluation is intended to inform the Board and Management discussion of the extent and nature of ADB’s NSO additionality, given the bank’s focus on expanding support for private sector. The evaluation will draw success factors and lessons from experience and make recommendations to help enhance the success of ADB’s private sector operations.
