A friend of mine from New York, called some hours ago telling me that she is having a really difficult presentation in front of the board of directors of an international company. The outcome of that presentation will determine if they will sign a contract with her company. Their are few tips that came to my mind:
Create a powerpoint presentation with four slides and only! Don't use not even one word, just images and arrows. You will find that it will assist you more than just reading.
Don't present yourself make a small introduction and get to the point, "we are here to discuss a)... b)... c)...".
Try to maintain eye contact. Not to just one of them, but all.
NEVER say mmm, aha. Use positive words and take small gaps if you need to think. Thinking is not a crime. On the contrary, they will appreciate it.
When you say something, you better mean it. Otherwise, it's better not to commit on something you can't fulfill.
Give room for questions. Dialogue is better than monologue.
