Write a project plan in a sheet that shows what's late

Help me write a project plan.

Goal: [what done looks like]
Deadline: [date]
People: [names and roles]
Tasks I know about: [list]
Things that could hold us up: [risks]

Ask me up to 3 short questions first if anything important is missing. Wait for my answers.

Then:
1. A task table with columns: Task, Owner, Start, Due, Status, Depends on.
2. Milestones with dates.
3. A risk list: risk, likelihood, impact, what we'll do.
4. A weekly 15-minute check-in agenda.

Only use what I've told you, leave blanks for anything I haven't given, and don't invent facts, dates or results. UK English.
