Business meeting agenda samples are available on the U.S. Department of State website, as well as MyCommittee.com and MeetingAgenda.org. MeetingAgenda.org offers a few different samples depending on the type of business conducting the meeting. The Department of State's website includes samples for executive teams and school boards.
The purpose of a meeting agenda is to outline the main issues to be discussed at the meeting in order to keep everyone in attendance on topic. The agenda allows the meeting to stay under control, as people know ahead of time what to expect for discussion. Those items are discussed in the order they're presented on the agenda.
