Tell me about a time when open issues remain unresolved because ownership and escalation are unclear. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed the closing dashboard, issue log, review notes, and management update and coordinated the action to prioritize close-critical items, coach reviewers, manage risk, and communicate decisions clearly. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
