How these map to the role

These are forecasting / economics cases: an ambiguous demand or investment question you frame into a model and a measurement, and a recommendation leaders can bet millions on. Two things recur — value is downstream ecosystem impact, not device margin, and the portfolio cannibalizes itself, so incremental ≠ gross.

Each answer is a coaching walkthrough: a Sample answer (clarify → approach → a simulated back-and-forth → a clear call), then a Deep dive with illustrative example, then a Grading rubric.
