Agenda is an abbreviation agenda sunt or agendum est, gerundive forms in plural and singular respectively of the Latin verb ago, agere, egi, actum "to drive on, set in motion", for example of cattle.
What is now known in English as an agenda is a list of individual items which must be "acted upon" or processed, usually those matters which must be discussed at a business meeting.
Steps on any agenda can include any type of schedule or order the group wants to follow.
Agendas may take different forms depending on the specific purpose of the group and may include any number of the items.
[6] In parliamentary procedure, an order of business, as the name may suggest, is the sequence of items that is to be taken up during a meeting.
[21] In Robert's Rules of Order Newly Revised (RONR), the "call" may be made by one member, and does not require a second.
The chair must then proceed to the scheduled item of business, unless the assembly decides otherwise by a two-thirds vote.
[22] The Standard Code of Parliamentary Procedure does not have this motion and instead suggests that a member can request that the body take up the scheduled item of business, or make a more formal point of order.
