This document discusses improving humanitarian performance through learning and evaluation. It notes that while NDMAs and humanitarian organizations have individually used approaches like evaluation, simulation, and training, there is potential for increased collaboration. Specifically, it outlines that NDMAs and humanitarian groups have taken some collaborative steps through joint evaluations, simulations, and capacity building, but more information is still needed on current learning approaches and where collaboration could be strengthened. The document raises questions about better understanding NDMA and humanitarian learning methods, what is effective, and how to identify optimal areas for increased cooperative efforts.
