Tell me about a time you inherited or built an operating review for a team and had to define a KPI hierarchy from top-line outcomes down to leading indicators. What was the business problem, how did you decide which metrics mattered most, and what tradeoffs did you make when data was incomplete or teams disagreed? Walk me through the actions you personally drove, including any business-flavored SQL or self-serve analysis you used to validate the metrics, and the outcome for the organization.
