To fully enter the definition of agenda, it is necessary that, first, we can know what its etymological origin is. In this sense, it must be stated that it derives from the Latin “thema” and this, in turn, emanates from the Greek “thema”, which can be translated as “main issue”.

It is called temary to the series of themes that are planned to be addressed in a colloquium , a chat or a meeting . The concept can also refer to the topics that are treated in a publication .
For example: “According to what I could see in the agenda, a good part of the congress will revolve around accessible tourism”, “I have read the agenda of this new edition of the magazine and I honestly did not find many notes of my interest”, “The conference at the cultural center will be next week and we have not yet defined the agenda”.
The agenda works like a guide or as a orientation . For the people who will attend a certain event, knowing the agenda allows them to know in advance what issues will be addressed. Those who must participate as speakers, on the other hand, can structure their interventions according to the stipulations of the agenda.
Suppose, in a Museum , a colloquium on the art history in Latin America . The organizers of the event, after holding meetings with the invited experts, define a syllabus that includes pre-Columbian artistic manifestations, art in times of conquest, the first works of independent America and autonomous artistic development in the continent, among other topics . Once the agenda has been agreed, they publish it on the museum's website and send it to the media for dissemination. Simultaneously, posters that are installed in the institution are printed so that potential attendees know what the meeting will be about.
Where we talk more frequently about agendas is in the field of opposition. And it is that people who, once they meet the requirements of the relevant call, want to take an exam of that type to get a place and become civil servants need to know what questions they are going to ask. Therefore, what they do is resort to knowing the official agenda and, from there, start looking for the most complete and study it to achieve the goal set.
In that case, it should be borne in mind that a syllabus in that sense is considered good as long as it complies with the following hallmarks:
-It is very complete and gives all the basic and most important information.
-It must be written in a coherent way.
-It has to have a clear and perfectly defined structure, because that, among other things, will allow the opponent to learn clearly each and every one of the parts that it deals with.
-It is recommended that, at the beginning, you have a schematic script that allows you to know this structure.
-You must have a bibliography that comes to endorse everything that is explained and detailed.
