The key to delivering an effective presentation on any topic is confidence in your own words and a thorough knowledge of the subject matter at hand. A topic that has been well prepared will directly influence the quality of your presentation so a deep understanding of the fundamentals is a prerequisite. Besides quality, the quantity or the number of slides in a presentation can decide the attention span of the audience and a terribly lengthy presentation that goes on for an hour is most likely to become uninteresting after a while.
The reason why Microsoft calls its presentation program Power Point, is that the whole idea behind a presentation is to make short but powerful points that draw the audience’s attention instead of dragging on with long drawn explanations.
Custom animations can be used to make a presentation livelier if it is full of apparently boring details. Similarly, using interesting but appropriate transitions between slides can keep your audience from wavering into the monotonous territory of dullness. Another important aspect of effective presentation is practicing several times so that you can work out the glitches and add polish to your presentation. Lastly, be prepared for questions that might be asked and rehearse answers for them.
