Your presentation reveals a lot about you. It shows your ability to plan, communicate, and think. Here's how to make a good impression the next time that you speak.

1) When planning a presentation, identify and write the goal for your presentation. Then study it to make sure that this represents what is expected of you. If needed, survey others by asking if this meets their needs for your presentation.

2) Plan your presentation so that it supports your goal. Make sure every point moves the audience toward accepting your goal and discard all unrelated information. Unrelated information, however interesting, distracts the audience and wastes time.

3) Think through your presentation from the audience's viewpoint. Consider what they know, understand, and expect. Similarly, consider what they need to know. Then plan a presentation that delivers this.

4) If possible, talk with key members of your audience to determine what they expect, know, and need from your presentation. These conversations will help you win support for your ideas, gain valuable insights, and practice parts of your talk.

5) Test your presentation with members of your audience, associates, or coworkers. Then pay attention to their reactions to your main points. If they're different from what you wanted, make adjustments to increase the effectiveness of your presentation.

6) Rehearse your presentation everywhere, anywhere, and with anyone. Rehearse. Rehearse. Rehearse. An unprepared presentation always appears unprepared. And that upsets the audience because they know their time is being wasted.

7) Rehearse your presentation with a clock. This makes sure your presentation fits into the time allotted. People dislike presentations that exceed the time limit. It also ruins the schedule for the event where you are speaking.

8) When preparing slides, overheads, or other exhibits, show only one key idea on each. Too much information confuses and upsets people.

9) Make sure that the information on the exhibit can be seen by everyone in the room. An exhibit is useless if no one can read it. And you can't rescue a useless slide by announcing, "I know that you can't read this." If the information is critical, then distribute copies as part of your notes.

10) When planning slides, test each slide by asking yourself, "Why am I showing this?" Make sure that each slide supports your talk. Otherwise, leave it out.
