The purpose of a technical presentation may be generalized as a forum where the speaker must either persuade or inform the audience on a particular topic which is interest to the speaker. The format in which information is conveyed to the audience is necessary both for the speaker and for the audience. If the speaker has a clear picture of the topic, then he or she can convey this picture to the audience. If a speaker does not have a clear picture, then the talk will be disorganized.

The organization of a technical presentation requires that the speaker must:

• understand what he or she wants to say,
• determine the overall structure (including order and flow),
• determine how the arguments will be presented (persuasion), and
• to present this in the required time.
