Investigate Sudden Revenue Drop: Steps and Metrics Analyzed

Scenario

A product’s weekly revenue has suddenly dropped.

Task

Describe, step by step, how you would investigate and diagnose the root cause of a sudden revenue drop. Specify the metrics, funnel stages, and segmentations you would examine.

Hints

Decompose revenue into multiplicative drivers (e.g., traffic × conversion × price/AOV × take rate).
Segment by acquisition channel, cohort, geography, device/platform, time of day/day of week, and product lines.
Consider experiments, pricing/fee changes, external market conditions, outages, and data quality.

Assumptions (minimal context for clarity)

You have access to product analytics, marketing data, revenue/transaction logs, and experimentation logs.
Revenue is primarily generated from user transactions (e.g., trades, purchases) with a fee or margin component.
