Agencies can be broadly classified into public and private sectors. Public agencies are typically government entities tasked with implementing laws, regulations, and public policies. They operate at various levels—local, regional, and national. For instance, the Environmental Protection Agency (EPA) in the United States is responsible for regulating environmental issues, while local health departments oversee public health initiatives in communities. These agencies are structured hierarchically, with a clear chain of command, which is essential for accountability and transparency in public service.
