Identify Growth Opportunities for New Payroll Feature Launch

Case Study: Driving Adoption of a New Automated Tax‑Filing Feature

Scenario

You are a data scientist partnering with a product manager on a payroll product. The team is about to launch a new automated tax‑filing feature for employer customers.

Task

How would you identify the biggest opportunities to drive user adoption? Specify:

  1. The metrics you would track from day one (and the funnel you expect to see).
  2. The user segments you would use to size each opportunity.
  3. How you would size and prioritize opportunities (e.g., TAM sizing, ICE/RICE).

Assume a phased rollout and typical payroll seasonality (e.g., quarter‑end filings).

Constraints & Assumptions

  • Preserve the scope, facts, inputs, and requested outputs from the prompt above.
  • If the prompt leaves a detail unspecified, state a reasonable assumption before relying on it.
  • Keep the answer interview-ready: concise enough to present, but concrete enough to implement or evaluate.

Clarifying Questions to Ask Guidance

  • Clarify the business objective, unit of analysis, time window, exposure definition, and primary metric.
  • State assumptions about instrumentation, randomization, sample size, and data quality.
  • Separate descriptive analysis from causal claims.

What a Strong Answer Covers Guidance

  • A metric framework with primary, guardrail, and diagnostic metrics.
  • A credible analysis or experiment design with clear assumptions and bias checks.
  • SQL/statistical logic for segmentation, variance, confidence, and data validation where relevant.
  • An actionable recommendation that explains trade-offs and next steps.

Follow-up Questions Guidance

  • What sanity checks would you run before trusting the result?
  • How would you handle novelty effects, seasonality, or selection bias?
  • What decision would you make if metrics disagree?
