Delivering presentations in a formal business environment takes skill and preparation, and it is not always done effectively.
Preparation: Business presentation requires the most diligent and meticulous preparation. Clients and employees expect confidence from the presenter - any display that this is lacking will seriously defect the impact of the presentation.
Slideshows and projectors: Organizing the presentation into main ideas in the form of slideshows is an effective way to ensure that the audience understands and absorbs the presentation. The slideshow is then projected onto a screen so the business presentation can be seen and heard by all present. Depending on the quality of the slideshow, this can also add an element of entertainment to the presentation, which is an effective tool for any formal delivery.
Hard copies: It is important, especially in lengthy business presentations, to dispense printed copies of notes and slides to the audience. Extended presentations often contain vast amounts of information which may typically include facts and figures, things which are not necessarily easy to remember after only a single presentation. Thus, printed copies of this information will give the audience something to refer back to should the need arise, so that they do not have to rely on memory alone.
Humor: It is fairly debatable whether or not humor should be included or even attempted in business presentation. When presentations are mundane or fact-laden, it is perhaps advisable to try and include a minimal amount of humor so as to maintain the necessary attention of the audience. It should not be over-emphasized, but should not be avoided completely if the presenter is able to include it, as humor is an asset to any presentation.
Intermissions and recap: In many instances a business presentation could drag on for hours. It is important in these situations to ensure regular intermissions. The average attention span for an adult is under half an hour, so delivering presentations which exceed this duration is a certain way to lose the attention of the audience. Have regular intermissions; when preparing the presentation, structure it in such a way that it allows for intermissions at regular times. Before or after each intermission, have a quick recap of the presentation before moving on to the next point. The recap should be interactive; either ask questions or let each person attending the presentation say something about what they have learned during the past session.
Conclusion to summarize: At the end of the presentation there should be a final recap which covers the entire scope of the presentation. The conclusion should summarize the main ideas behind the presentation and perhaps review any especially important facts or figures. This will ensure that everything is absorbed by the audience thoroughly, and allow everyone to ask questions if they have trouble with understanding something. Also, not everyone has the same attention span, so while you have allowed intermissions to cater for the general attention span, someone might have missed something important at some stage, and this final summary is the ideal time to ensure that this is attended to.
