蘋果首席宣傳官：PPT三大制作原則

You’ve just been asked to give a project update to your classmates in one hour during lunch time next Thursday.

你剛剛被要求在下周四午餐時間的一小時里，向你的同學展示一份PPT。

Quick…

How many slides will you use？

How much text can you put on them？

How long should you speak—more than one hour， or less？

趕緊想……

你要使用多少張PPT？

你要在PPT上放多少文字？

你應該講多長時間——一個小時以上還是不到一小時？

Don’t know？ Guy Kawasaki， a famous author and venture capitalist， has the answers and they may surprise you.

你還不知道對嗎？著名作家兼風險投資人，蓋伊·川崎，能給你答案，而這些答案或許會讓你感到驚訝。

1. 10 Slides Constrains the Presenter to Choose Wisely

只能用10張PPT，要求做展示的人要精心選擇

Most people probably have 20， or 30， or 100 slides for a 1-hour presentation. Trimming this number down to 10 forces you to evaluate the necessity of each and every slide. Just like every element of your presentation， if the slide isn’t necessary， it should be cut.

It also encourages a presenter to design wisely. Often a single well-designed diagram eliminates the need for 5 bullet-point slides.

在一個小時的展示中，有的人可能會使用20張、30張甚至100張PPT。減少PPT的張數迫使你評估每張PPT存在的必要性。正如你的現場展示中的每一個元素一樣，如果某張PPT是不必要的，那就刪了它。

限制PPT張數，同時也鼓勵了做展示的人精心地設計PPT。一張設計精巧的圖表常常可以替代5張普通PPT的效果。

2. 20 Minutes is Long Enough to Communicate Something Big

20分鐘足夠讓你充分地傳達自己的思想

Just like the constraint on the number of slides， a constraint on your speaking time will force you to edit mercilessly. Trim the sidebar jokes. Trim the gratuitous such as “I’m happy to be here” pleasantries. Trim the stories which aren’t essential to conveying your message. Trim the details that only 5% of the audience cares about. When you are able to trim all the extras， you can communicate with precision and concision.

Martin Luther King Jr only needed 17 minutes to share his dream. What makes you think you need more？

就像限制PPT的張數一樣，限制你演講的時間能迫使你將自己的語言濃縮提煉。省去一些花絮性質的笑話。省掉不必要的諸如“我很高興在這里給大家做展示”之類的客套話。省去一些對傳達你的思想來說并不必要的故事敘述。省去那些只有5%的觀眾才關心的細節。當你能夠省去這些多余的話時，就能精確而又簡明地傳達自己的思想了。

馬丁·路德·金只用了17分鐘來分享他的夢想，是什么讓你認為你需要更多的時間呢？

3. 30-Point Font Guarantees Readability

30磅字號確保了文本的易讀性

Unless you have a very large audience and a very small projector screen， 30-point font should be readable by everyone in your audience. Bigger is probably better， but this is a sensible lower threshold to adopt. While a 30-point font still allows you to put too many words on a slide， at least your audience will be able to read them.

除非你有非常多的觀眾和一個非常小的投影機屏幕，否則30磅字號應該足夠讓你的每一個觀眾都看得清了。字體大一些可能會更好，但是30磅字號是一個可采用的明智的較低的下限。在30磅字號允許你在一張PPT里放很多字的同時，至少你的觀眾是可以看清它們的。
