The launch decision
Shipping is a decision with a shape — a rollout schedule, kill criteria written before launch, an owner for the call, and a plan for the week after. This lesson builds that shape, works through the two hard cases (a deadline that arrives before the evidence, and a regression found at 25% rollout), and covers the launch questions interviewers use to find out whether you have actually shipped anything.
What you'll be able to do
- Design a staged rollout with a stated purpose for each stage
- Write kill criteria and a rollback plan before launch, and name who makes the call
- Handle a deadline that arrives before the evidence does, without either lying or missing it
- Run the week after launch: what you monitor, what you communicate, and when you declare it done
