The two most common purposes of business presentations are to inform and persuade. Business presentations are designed to communicate information to an audience in a clear and concise way, and to persuade the audience to accept and act on that information. While analyzing and synthesizing information may be part of the presentation, they are not the primary purposes. Regulating and validating are not commonly used purposes of business presentations, and illustrating and entertaining may be secondary goals but not the primary purposes. Finally, while buying and selling may be part of some business presentations, it is not the primary purpose.
