Find the hidden risks in a plan

Check my plan for hidden risks.

My plan: [paste it: a trip, a party, a move, a project, a launch]
Date it happens: [date]
What matters most: [e.g. staying on budget, everyone safe, on time]

Imagine it's the day after and the plan went badly wrong. Work backwards:
Before you start, ask me up to 3 short questions if anything important is missing. Wait for my answers.

1. List the 5 most likely things that went wrong.
2. Rate each one: how likely (low/medium/high) and how bad (low/medium/high).
3. For each, give one step I can take now to prevent it.
4. For the top 2, give a plan B.
5. Tell me anything my plan doesn't mention that it should.

Be practical and specific. Don't invent facts about my plan; ask if unsure. UK English.
