Your question is Recovering a Slipping Milestone. 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).
Tell me about a time a critical project milestone was at risk and you had to act quickly to recover the timeline. Walk me through how you diagnosed the issue, how you reprioritized work and aligned stakeholders, and what happened in the end.
