Although some think of presentations in a business meeting context, there are often occasions when that is not the case. For example, a non-profit organization presents the need for a capital fund-raising campaign to benefit the victims of a recent tragedy; a school district superintendent presents a program to parents about the introduction of foreign-language instruction in the elementary schools;an artist demonstrates decorative painting techniques to a group of interior designers; a horticulturist shows garden club members or homeowners how they might use native plants in the suburban landscape; a police officer addresses a neighborhood association about initiating a safety program.
Presentations can also be categorized as vocational and avocational. In addition, they are expository or persuasive. And they can be impromptu, extemporaneous, written, or memorized. When looking at presentations in the broadest terms, it’s more important to focus on their purpose.
