Net-Mapping is a participatory social network method which can be used to conduct a capacity and needs assessment. It invites participants to engage with key issues on a deeper lev- el while considering the experiences of different stakeholder groups within a given network or system. This paper concentrates on the process of implementing the Net-Mapping meth- od in the context of Tunisia’s Food Safety System (FSS). From the design, its implementation and the analytical steps that were taken, it is recommended to conduct the Net-Mapping method with various homogeneous group of participants, to provide ample time for discussions, to formulate specific re- search questions in advance, and to remain flexible and curious in the process. This method invites dialogue in an inquisitive and engaging manner to identifying the needs and capacities in a network or system, while navigating different political agendas of key stakeholders. When knowledge is power, then communication is key.
