Elements related to Style 风格方面
1) Sell the idea
You must keep in mind that you are selling something to your audience, whether it be a product, a project, an idea, a strategy, concept or anything else. The primary goal of your presentation must be to convince the audience that they should "buy".
2) Tell a compelling story
Your presentation of the idea and its ramifications (结果) must be so thorough, attractive and convincing that the audience is eager to buy into what you're selling. Basically, you're capturing their imagination.
3) Be concise
State your ideas, goals, and benefits received in a crisp (简洁的), brief and meaningful manner.
4) Support your idea and story
Using relevant facts and figures that drive home the key message that you are trying to get across to your audience. 用相关的事实和数字让你的听众接受你想让他们了解的关键信息。
Elements related to Content 内容方面
1) Key objectives
State the purpose, scope and objectives of the presentation in a clear, concise manner. This can include both qualitative and quantitative elements.
Tell the story on how to achieve your objectives (i.e. what activities or tasks need to be done). This is where you identify and describe your strategy (i.e. What, When, Where, How).
4) Supporting evidence
Support the main body with relevant business charts to illustrate and highlight key figures. Use relevant facts to support your story.
5) Call to action
Creating a sense of urgency for the approval of what you're presenting ASAP, and instilling a sense of loss if your idea does not proceed beyond this point.
