Summary

Interviewed at Flatiron Health, got a product analytics case question about diagnosing a usage drop. Pretty lean on details from my end but the question itself was meaty enough to chew on for a while.

Questions Asked (1)

Q1

One of our tools saw a 20% drop in usage over a two-week period. How would you go about diagnosing what happened?

I started with the obvious stuff: did anything ship recently, any infra changes, any external events.

Suggested Approach

Start by clarifying the metric definition and confirming the drop is real, not a data artifact. Then systematically segment the data to isolate the cause, considering internal changes, external factors, and user behavior shifts. Finally, prioritize hypotheses and validate with qualitative and quantitative evidence.

Pro tip: In healthcare, always consider regulatory or data privacy changes that could affect tool usage, and check if the drop is consistent across user segments or isolated to a specific group.

1. Clarify and Validate the Metric

Define what 'usage' means (e.g., daily active users, sessions, actions) and verify the data pipeline for errors or tracking changes. Confirm the drop is real and not due to logging issues.

2. Segment the Data

Break down usage by dimensions like user role, geography, device, time, and feature to identify if the drop is broad or concentrated. Look for patterns that suggest a specific cause.

3. Generate Hypotheses

Brainstorm potential causes: internal (product changes, bugs, releases), external (seasonality, market events, competitor actions), and user behavior (onboarding, training, workflow changes).

4. Investigate and Validate

Use data analysis, user interviews, and logs to test hypotheses. Check release notes, support tickets, and system status for anomalies. Correlate with other metrics to confirm impact.

5. Synthesize and Recommend

Summarize findings, identify root cause, and propose next steps: fix if internal, adapt if external, or further investigate if inconclusive. Communicate clearly to stakeholders.

Key Points to Mention

  • Metric definition and data validation to rule out tracking errors
  • Segmentation by user cohorts, time, and product features
  • Internal factors: recent releases, bugs, UI changes, or pricing updates
  • External factors: seasonality, regulatory changes, competitor launches
  • User behavior: onboarding, training, or workflow changes
  • Qualitative methods: user interviews, support tickets, and feedback
