Tell me about a time when unexplained stock differences are adjusted without root cause. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed the count sheet, transaction history, recount, and approval and coordinated the action to investigate location, transaction timing, unit of measure, and counting error. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
