Summarise a Long Briefing Document in Five Points

There is a thick briefing document on your screen and a meeting in twenty minutes. You will not read it all. This extracts the five points that matter: the headline, the key evidence, the decisions in play, the risks, and what you might get asked. Good for anyone walking into a room underprepared and wanting to fix that fast.

3. What is being asked of you: any decision, input, or action the document requires from attendees
4. The main tensions or open questions: what is not resolved or agreed
5. What you would look foolish not knowing: the one fact or context point that everyone in the room will assume you know
