Where they differed most

The task — Slide on a diet

This slide is for a 5-minute update to the senior team. Cut it to the bullets that help them DECIDE something — max 4 bullets, nothing else added. Slide 'Office move update': - Project kicked off on 4 June as agreed - Weekly meetings have been held every Tuesday - The project team has worked very hard - Three sites shortlisted, all within 2 miles of the station - Broadband installation lead time is 6 weeks, which is now the critical path - We looked at many options for furniture - Costs are tracking 8% under the £90k budget - The tone of meetings has been very positive - Decision needed by 30 September or we lose the preferred site.

- Broadband installation lead time is 6 weeks — now the critical path
- Costs tracking 8% under the £90k budget
- **Decision needed by 30 September or we lose the preferred site**

Everything else (kickoff date, meeting cadence, team effort, tone) is progress narration, not decision input — cut it. The final bullet is the ask, so it's bolded to make the required action unmissable in a 5-minute slot.
