Turn a Marketplace Data Insight into an Actionable Product Plan
Turn a Marketplace Data Insight into an Actionable Product Plan
You are given a downsampled, observational dataset from a two-sided live-commerce marketplace. The dataset includes information about the buyer journey, seller exposure, browsing, and transactions, but the schema is not predefined.
Your task is to prepare a 25-minute take-home presentation focused on one key insight. The goal is to go beyond simply reporting a correlation; you must translate the evidence into a feasible product recommendation and a credible plan for measuring its success.
Constraints & Assumptions:
- Acknowledge that the dataset is a sample and discuss how sampling affects rates, totals, rare segments, and uncertainty.
- Clearly distinguish between observations directly supported by the data and hypotheses generated from product usage.
- If proposing additional logging or data, identify it as a limitation rather than assuming its existence.
- Consider the impact of your findings and recommendations on buyers, sellers, and the overall health of the marketplace.
- Do not claim causal effects based solely on observational analysis.
The presentation should cover three parts:
- Find and Validate One Decision-Relevant Insight: Describe your process for inspecting the data, selecting a unit of analysis, defining cohorts and denominators, testing the robustness of a candidate insight, and ruling out alternative explanations. Explain why the insight is actionable.
- Convert the Insight into a Product Recommendation: Propose a concrete intervention, identify the user problem it addresses, explain its proposed mechanism of action, and state the most significant risks. Prioritize this recommendation against plausible alternatives without assuming unavailable information.
- Design the Evaluation and Launch Plan: Define the primary metric, guardrail metrics, randomization unit, analysis population, and decision rule for a launch test. Discuss potential interference between buyers and sellers. If randomization is not feasible, propose a defensible causal-inference alternative and its assumptions. Conclude with a staged launch and monitoring plan.
