Shannon and Weaver are considered one of the most important seeds from which communication theory has grown.

If a point or concept is not clear, the trainer is present to answer questions and go into further detail. Live trainers also serve to add personality to the program, and can provide individual attention to persons or groups if needed. Prerecorded voices used in presentations may seem cost-effective and get the job done, but there is no guarantee that the communication was fully understood. Handouts serve to reinforce oral and visual components, and can go into further detail if desired or warranted. Handouts allow participants to follow along with presented information, make notes, formulate questions or refer to key points in the future as a "refresher course."
