This research project was contracted by the Research and Policy in Development (RAPID) programme of the Overseas Development Institute (ODI). The aim of the project was to produce case studies of three NGO networks in Cambodia to back up the initial COSECAM study of the effectiveness of the network model within the country, in terms of influencing policy and carrying out its own mandate. The project uses the function/form framework (as detailed by the RAPID website to identify: i) the functions of the network; ii) the network’s structure and how this affects its functions; iii) the ways in which it attempts to carry out its functions; and iv) its successes and failures to do so.
