||Uncertainty and risks are part of humanitarians' daily routine. Most of the time, infrastructures are damaged or non-existent, the political climate is highly volatile, communication means are insufficient, and so on. Therefore, humanitarian organizations often have to find original methods to implement their supply chains. They may also face recurrent problems, that requires them to change the way they operate. And yet, as they lack the time and resources to reflect on the lessons learnt, most of their best practices and issues are neither captured nor communicated. The aim of the study is thus to propose a framework to capitalize humanitarians' knowledge and know-how, to analyze both gaps and best practices and learn from one operation to another. To this end, we propose a framework derived from traditional Enterprise Modelling tools, adapted to fit relief chains' specificities. Field applications are then given to illustrate our approach and its beneficial effects.
