Rewrite the opening and closing of a talk

Write the opening and the closing of this presentation. ***These are the two parts people remember and the two that get the least preparation.***

**The opening — the first 30 seconds:**
1. ***Not an agenda. Not an introduction of myself or the team.* **Those cost the attention I need most**
2. **Options, and what each is betting on:**
   - **The conclusion first** — ***works when they came to decide***
   - **The problem, concretely** — ***when they do not yet agree there is one***
   - **A number that does not fit their expectation**
   - **What changed since last time** — *for a recurring audience*
3. ***What the opening has to promise that the deck delivers.* **Flag any mismatch**

**The closing:**
1. ***Not "thank you" and not a summary.* **The last slide is up during the entire discussion — it should be working**
2. **What it carries:** ***the decision I am asking for, or the next action, with who and by when***
3. ***What I want repeated when someone describes this to a person who was not here.* **Make that one sentence explicit**

**Also:**
- **What to say if the time is cut in half on the day** — ***the 60-second version, built from these two ends***
- ***Where my opening and closing contradict each other*** — **more common than it sounds**

⚠️ ***Use only what is in the deck. Do not invent a hook, a statistic, or an anecdote.***
