Business Metrics Definition and Strategy Questions

Emphasizes defining meaningful metrics and measurement frameworks that answer business questions and drive decisions. Candidates should be able to distinguish between count metrics, ratio metrics, and rate metrics; select appropriate observation windows and time alignment for retention, churn, and conversion analyses; account for multiple user touch points and events when attributing actions; and identify leading versus lagging indicators. This topic covers designing metric definitions that avoid double counting, selecting denominators and numerators that match the business question, segmenting users for insight, and documenting business logic to ensure consistency. At senior levels expect discussion of trade offs between simplicity and fidelity, governance of metric definitions, and how to prioritize which metrics matter for different stakeholders.

Multiple product teams publish metrics that appear inconsistent (e.g., MAU differs by 8% across dashboards). Describe a cross-team remediation plan: how to identify the source(s) of difference, coordinate fixes, and establish SLAs and tooling to prevent reoccurrence.

How would you define and measure churn for a product with highly irregular user activity (e.g., users engage every 2-6 months)? Propose metric definitions (binary and probabilistic), describe methodology (e.g., survival analysis), and explain how to operationalize alerts for at-risk users.
