Development is a complex field involving governments, businesses, non-governmental organizations, and intergovernmental agencies. Organizations address short term challenges – such as disaster relief – and work towards long-term goals – such as poverty reduction and infrastructure building. The field is undergoing a significant shift in emphasis from direct delivery of services to capacity building and collaboration with local partners. There is a growing demand for professionals to respond to these challenges in a variety of roles, including: administrators, fundraisers, program managers, business development experts, teachers, researchers, policy analysts, project managers, program monitors, and others.
