This report responds to a recommendation by the OECD Council in the In-Depth Evaluation for the Development Assistance Committee (DAC) to undertake a strategic Reflection Exercise. The objective of the exercise was to address how to sustain and increase the relevance of the Committee in the changing development landscape over the next ten to fifteen years by reviewing its role, structure, functioning and composition. The result is to form the basis of a revised DAC mandate, expected to be renewed by Council for five years starting 2011.
