The prompt · ChatGPT

Help me plan backwards from a deadline.

Deadline: [date and time]
What has to be handed in or ready: [e.g. a report, a house sale move, an event]
Tasks I know about: [list them, with rough times if you know]
Hours I can give it each week: [e.g. 5 hours, evenings only]
Things I'm waiting on from other people: [e.g. figures from a colleague, a quote]
Other big things in my diary: [e.g. holiday 12 to 19 May]

Before you start, ask me up to 3 short questions if anything important is missing. Wait for my answers.

Then:
1. My tasks in order, each with a time estimate (mark any you've guessed).
2. A backwards timeline with real dates, from the deadline to today.
3. For each task, the "last safe start" date.
4. Three checkpoints where I check I'm on track, and what "on track" looks like.
5. If it doesn't fit, say so plainly and give me three options: cut something, get help, or ask for more time, with a short polite message asking for an extension.

Use only the tasks and hours I've given you. UK English.
