A technical expert must not only know, understand and interpret complex data but also present the facts through clear, concise and correct speech. The first step in conveying technical information is to establish a clear understanding of when, where, why, how, what and to whom your information is to be presented. The next step is to structure the presentation. The structure of a presentation includes the organization of ideas, the definition of major sections and the transitions between sections. A logical structure coupled with techniques to illustrate, emphasize and explain central themes will assist your audience to understand the core message.
