Question

What is meant by three step oral presentation process?

Answer 1

Identify the core point you want to make. What is the crucial bit of information you want to get across to the audience? Think of this as the thesis or theme of your presentation. People can only process a limited amount of information in one sitting, so don't try and hit them with 10-15 different ideas and points. Instead, find one good idea and expand on it fully. The best points are unexpected, exciting, or controversial -- the sort of idea that piques people's interest and give you lots of room to elaborate, so think of a unique take on your topic.[1]
Is your presentation trying to be persuasive? If so, ask yourself "what do I want the audience to do/believe when they leave?"
Is your presentation informative? If so, ask yourself "what does the audience need to know when they leave?"
Is your presentation a sales pitch or business related? Your presentation needs to make someone pull out their wallet at the end, so the product and it's uses must come first.
