The role of the NGO in partnership arrangements for service delivery is therefore generally associated with communities, particularly poor communities. The efficacy with which NGOs can perform roles will vary according to the capacity and interest of the organisation and specific individuals, and according to whether or not it has an established relationship with a community. The first book in this Municipal Capacity Building Series14 proposed that the potential roles of NGOs include mediation, facilitation, coordination, capacity building, community development, dispute resolution and post- project sustainability. These and other key roles are discussed in relation to service partnerships below.
