Tell me about a time when forecast changes are not linked to business drivers. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed the approved assumptions, forecast model, and variance explanation and coordinated the action to validate assumptions, volume, price, cost driver, timing, and owner input. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
