This chapter aims to provide guidance on the critical steps needed to ensure the inclusiveness of stakeholder engagement processes, taking into account recent trends (newcomers) and the long-standing need to better engage “unheard voices”. Knowing who is responsible for w'hat and at which level is a first step towards understanding the stakeholder “landscape” and identifying redundancies and gaps in the institutional framework that impact policy coherence and sector performance. A stakeholder mapping can be used to identify the core functions of stakeholders involved in the sector and to assess how' effective they are in carrying them out.
