In my opinion, an efficient PowerPoint presentation owes much to the speaker’s elaborate planning and careful preparation as well as consummate PowerPoint skills. Then I would like to express my view of how to make an efficient PowerPoint presentation.
Content: use more graphics rather than technical terms
If necessary please try your best to express your thoughts by graphics which can make sure your idea understood by your audience easily. And at the same time make your presentation more attractive and impressive.
If your speech content is relatively professional, please take your audience into consideration. You’d better make every effort to avoid the terms which is difficult to understand by your audience. If you have to, please make sure you explain it clearly. Remember that if your audience can not understand what you are talking about, you are just wasting of your time. No need to say make an efficient PowerPoint presentation.
Effects: avoid or reduce the use of effects on formal occasions
It is not recommended to add effects when making PowerPoint presentations on formal occasions. A simple and regular PowerPoint is always above praise but also criticism. Of course it is favored to add some effects on informal occasions but in my opinion it is better to add not more than three kinds. Then your PowerPoint can still keep concise instead of messy.
Image: wear suits and keep smiling
Please wear suit when making a PowerPoint presentation. It helps you to leave an authoritative impression to your audience. I have not ever seen anyone wearing jeans or shirt to make a speech. Do not mention about Bill Gates, he can do this and if you were Bill Gates I would say nothing. And before the presentation, keep energetic and positive while making sure you are proper dressed up. I believe your attitude will have a great influence on your audience. Besides, make sure that keep eye contact with your audience during the speech so that you can communicate with them through eye contact. You can recognize what they want and respond them in time. Thus the audience will know you care about them.
These are all my advice and hope it is useful to you.
