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).
When a program is failing to meet its milestones, what is your immediate process for course correction? Explain how you would diagnose the source of slippage, establish facts, align stakeholders, and decide whether to adjust scope, resources, sequencing, or timing. Describe the communication, recovery plan, and follow-up mechanisms you would use to confirm that execution is back on track.
