Our expertise in monitoring and evaluation allows us to accompany institutions and organizations in this key activity. This support is offered at all stages of the intervention; from the development of the project in order to optimize its strategies and logic, to the end of the implementation of the intervention to assess the effects and impact. Multidisciplinary teams (economists, public health specialists, epidemiologists, sociologists, communication experts, lawyers, etc.) can be deployed for ongoing monitoring of the implementation or evaluation of any component (relevance, logic, effectiveness, economics, implementation, effects, impact, etc.) of the intervention and the valorization of results.
