This paper provides a brief description of the key points an engineer or scientist must consider when preparing for a technical presentation. Planning, organization, construction, and presentation methodology are all explored in a manner to allow a speaker to review presentation material and style and to improve any areas which appear to be weak. Among particular items discussed are: word selection, meaningless verbal interjection (e. g. , ″OK″ , ″you know″ ), voice control and variation, gestures (appropriate or distracting) and visual aids.
