Prior to your scheduled presentation, attend a meeting of this particular group to observe how this audience reacts to other speakers. Know in advance what the audience expects from you. Do some research. Be a detective. Align your presentation with your skills.
Some speakers like to use visuals, handouts, or props.
Some prefer to move around while they speak. Some are humorous. Some are stirringly dramatic. Use your individual gifts and strengths when you address an audience. One of the best ways to analyze your own unique presentation style is to videotape your presentation.
