Product management · Execution — prioritising, reading results, and shipping

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.
