Evidence coming from research and evaluation can help you understand what works, where, why and for whom. It can also tell you what does not work, and help you avoid repeating the failures of others by learning from evaluations of unsuccessful humanitarian programmes. Evidence can also guide the design of the most effective ways to deliver specific interventions. This guide has been created to help you navigate around using evidence for your own purposes. If you have any questions or wish to request a free hard copy of the guide, please contact Claire Allen or Karl Blanchet.
