Your question is Recovering When Milestones Slip. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).

Describe the steps you would take to assess the risk, identify recovery options, communicate with stakeholders, and decide whether to replan, descope, or escalate. Explain how you would protect downstream milestones and prevent the issue from recurring.
