Core Framework: What-Why-How
核心框架:What-Why-How结构
Every technical presentation should follow this structure:
text
┌─────────────────────────────────────────────────────────────┐
│ WHAT (10% of time) - The Hook │
│ "Here's the problem/opportunity we're addressing" │
├─────────────────────────────────────────────────────────────┤
│ WHY (30% of time) - The Context │
│ "Here's why it matters and why you should care" │
├─────────────────────────────────────────────────────────────┤
│ HOW (50% of time) - The Solution │
│ "Here's how we solve it / how it works" │
├─────────────────────────────────────────────────────────────┤
│ CLOSE (10% of time) - The Call to Action │
│ "Here's what you should do next / key takeaways" │
└─────────────────────────────────────────────────────────────┘每一场技术演示都应遵循以下结构:

Slide Design Principles
幻灯片设计原则
The Rules
规则
- One idea per slide - If you need "and" in the title, split it
- 5-7 words per bullet - Slides are cues, not scripts
- Visual > Text - Diagrams, screenshots, code
- Consistent design - Same fonts, colors, layouts
- Readable from the back - 24pt minimum for body text
- 每张幻灯片一个核心观点 - 如果标题需要用“和”连接,拆分幻灯片
- 每个项目符号5-7个单词 - 幻灯片是提示,不是脚本
- 视觉优先于文字 - 图表、截图、代码
- 设计风格统一 - 相同字体、颜色、布局
- 后排观众可清晰阅读 - 正文字体最小24号
What Works
优劣对比
| Element | Good | Bad |
|---|---|---|
| Titles | Action-oriented, specific | Generic, vague |

Handling Q&A
问答环节处理
Techniques
技巧
Repeat the question: Ensures everyone heard and gives you time to think.
Clarify if needed: "Are you asking about X or Y?"
Acknowledge good questions: "That's a great point..."
It's okay to not know: "I don't have the answer to that, but I can find out."
Defer if needed: "That's a bigger topic—let's discuss offline."
Bridge to your message: "That relates to the point about..."
重复问题: 确保所有人都听到,同时给自己思考时间。
澄清问题: “你是问X还是Y?”
认可好问题: “这个问题很棒……”
不知道答案也没关系: “我暂时没有这个答案,但我会后会查清楚告诉你。”
必要时推迟解答: “这个话题比较深入,我们会后再讨论。”
关联核心内容: “这个问题和我们之前提到的……有关联。”
Difficult Questions
棘手问题应对
| Type | Response |
|---|---|
| Challenge to your approach | "That's a valid concern. Here's how we thought about it..." |
| Out of scope | "Good question—that's outside what we covered. Let's take it offline." |
| Hostile tone | Stay calm, address the content, not the tone |
| Show-off question | "Interesting point. Let me address the practical aspect..." |
| Rambling non-question | "Let me make sure I understand your question..." |
| 类型 | 回应方式 |
|---|---|
| 质疑方案 | “这是个合理的顾虑。我们是这样考虑的……” |
| 超出范围 | “这个问题很好,但不在本次讨论范围内,我们会后再聊。” |
| 语气敌对 | 保持冷静,聚焦问题本身而非语气 |
| 炫耀式问题 | “这个观点很有意思。我来谈谈实际应用层面……” |
| 冗长无意义的问题 | “我确认一下,你是想问……吗?” |
Timing and Pacing
时间分配与节奏
Time Allocation

- Vary energy (not monotone)
- Build to key points
- Use silence strategically
- End on time (or early!)
- 开场有力(不要浪费前几分钟)
- 调整语速和能量(不要单调)
- 逐步推进到核心要点
- 合理使用停顿
- 准时结束(甚至提前!)
Practice Routine
练习流程
- Read-through: Time yourself reading slides aloud
- Talk-through: Practice without looking at slides
- Full run: Present to someone or record yourself
- Cut ruthlessly: If over time, remove content
- 通读练习: 朗读幻灯片并计时 2.脱稿练习:不看幻灯片进行演示
- 完整演练: 给他人演示或录制自己的演示过程
- 果断删减: 如果超时,移除非核心内容
