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).
You are advising a product team that wants to ship a change to one of its core surfaces, but leadership wants an estimate of the impact before launch. You have historical usage data, funnel metrics, and some prior experiments, but the new change has not been tested yet.
How would you estimate the impact of a product change before launching it?
