The nature of humanitarian action is characterized by the immediate response to several humanitarian needs caused by climate changes, various crises or natural disasters. As a result, the documentation process and the perfect design of humanitarian services programs are exacerbated, and this may produce a lack or loss of basic data. 

Evaluators in the humanitarian sector face a wide array of challenges, basically  the lack of security and the difficult access to the affected populations, especially in remote areas or areas with damaged infrastructure networks as well as the poor  institutional memory in humanitarian action due to  the high turnover of staff, the various humanitarian actors involved, and the blurring of boundaries between the  responsibilities of each party, especially in large-scale crises, in addition to the fact that in hotspot areas , channels of communication with evaluators are  of low importance.

The concept of humanitarian action has expanded from saving lives to include improving livelihoods, protection and assistance. The challenges faced by the evaluation process in the humanitarian sector require dealing in an unconventional manner according to a clear methodology that allows us to accept a lower level of accuracy in the evaluation versus credibility.
