A non-governmental organization (NGO) is a not-for-profit organization that is independent from states and international governmental organizations.

Operational NGOs seek to “achieve small-scale change directly through projects.” They mobilize financial resources, materials, and volunteers to create localized programs. They hold large-scale fundraising events and may apply to governments and  organizations for grants or contracts to raise money for projects. They often operate in a hierarchical structure, main headquarters being staffed by professionals who plan projects, create budgets, keep accounts, and report and communicate with operational fieldworkers who work directly on projects.
Operational NGOs deal with a wide range of issues, but are most often associated with the delivery of services or environmental issues, emergency relief,  and public welfare.
Operational NGOs can be further categorized by the division into relief-oriented versus development-oriented organizations;
according to whether they stress service delivery or participation; whether they are religious or secular, and whether they are more public – or private – oriented.
Although operational NGOs can be community-based, many are national or international.
The defining activity of operational NGOs is the implementation of projects.
These organizations are looking for exposure to promote their causes.
