This thesis conducts a comparative study of international organizations in regard to their effectiveness towards addressing humanitarian concerns in Haiti. The three case studies are the operations of the United Nations, Catholic Relief Services, and REBUILD Globally, predominantly after the January 2010 quake. The hypothesis supported in this study is that the services of smaller organizations prove to be more successful than larger NGOs, although they do not have the immense resources of organizations such as the United Nations. The independent variables are type and quantity of funding, form of humanitarian work, and duration of support. All three variables establish the degree of overall effectiveness of the organization. This topic is significant because NGOs are rising in importance and influence in the international community as the average individual can now be involved in the foreign arena. It is important to study what is truly effective in humanitarian aid rather than assuming 'the bigger the better.'
