Tell me about a time when depreciation continues after disposal or uses an incorrect useful life. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed the asset register, disposal document, and depreciation schedule and coordinated the action to verify useful life, depreciation method, disposal approval, and gain or loss calculation. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
