Our expertise in monitoring and evaluation enables us to support institutions and organisations in this key activity. This support is offered at every stage of the intervention, from the design of the project in order to optimise its strategies and logic, to the end of the intervention’s implementation in order to assess its effects and impact. Multi-disciplinary teams (economists, public health specialists, epidemiologists, sociologists, communication experts, legal experts, etc.) can be deployed for ongoing monitoring of implementation, or evaluation of any component (relevance, logic, effectiveness, economics, implementation, effects, impact, etc.) of the intervention and exploitation of the results.
