For a product or feature of your choice: 1) Define 4–6 success metrics you would use to evaluate it. 2) If the primary metric suddenly drops, outline a step-by-step root-cause investigation plan. 3) Identify one leading metric you would monitor and justify why it predicts the primary outcome. 4) List the key business questions stakeholders will ask and how you would answer them analytically. 5) Propose meaningful user segments to slice the metrics and explain what each segment could reveal.
