I started by trying to define 'inactive' which felt like the right move but I probably spent too long on it.

Suggested Approach

Start by clarifying what 'inactive' means and how it's measured, then systematically segment the user base to identify patterns and potential causes. Propose a data-driven investigation plan that combines quantitative analysis with qualitative insights, and prioritize hypotheses based on impact and ease of testing.

Pro tip: Demonstrate product thinking by linking inactivity to business metrics like retention and revenue, and suggest a cross-functional approach involving data science, product, and engineering teams.

1. Define and Validate the Metric

Clarify the definition of 'inactive' (e.g., no login in 30 days, no streaming activity) and verify the data source and calculation method. Ensure the 10% figure is accurate and consistent across reports.

2. Segment the Inactive Users

Break down the inactive group by dimensions such as demographics, device type, subscription plan, tenure, and geographic region to identify patterns. Look for correlations with recent product changes or external events.

3. Form and Prioritize Hypotheses

Generate potential causes (e.g., UI changes, content gaps, technical issues, seasonal trends) and prioritize them based on impact and likelihood. Use data to quickly validate or eliminate hypotheses.

4. Conduct Deep-Dive Analysis

For top hypotheses, perform detailed analysis: cohort analysis, funnel analysis, A/B test results, and user surveys. Engage with customer support and social media to gather qualitative feedback.

5. Recommend Actions and Monitor

Propose actionable solutions (e.g., re-engagement campaigns, product fixes) and define success metrics. Set up monitoring to track changes and iterate.

Key Points to Mention

  • Define 'inactive' clearly and ensure alignment with business goals.
  • Segment users by behavior, demographics, and device to uncover patterns.
  • Use cohort analysis to see if inactivity is increasing over time or specific to certain groups.
  • Consider both internal factors (product changes, bugs) and external factors (competition, seasonality).
  • Leverage qualitative data like user surveys and customer support tickets.
  • Propose experiments (e.g., A/B tests) to validate causes and measure impact of interventions.
