Pavlo’s approach
To make a decision we should define metrics for long term gains of these features. The main revenue metrics could be:
- User lifetime spending
- Churn rate
- Earnings per user per period (monthly, annually, erc)
- New free/paid (tiers) users per period
Additional metrics, that can support the decision could be:
- DAU
- Session duration
- Number of sessions per user per period (day, week, month)
- Segments behaviour (age, regions, interests) - which features they prefer, how much they pay
Assuming we have data which shows us that mid age users have the highest level of lifetime spending but their churn rate is also high. Then we should target the first initiative as a main one - improving personal content recommendation, unless there is other data which shows that improved user engagement or social aspect can contribute more to overall revenue. That could be - new users are likely to buy subscription if their initial engagement is high, or users are likely to buy a higher tier subscription if they get social features.
Problem Analysis:
Netflix facing prioritization challenge with limited Q3 engineering resources across three high-impact initiatives targeting different strategic pillars: retention (churn reduction), engagement (time spent), and growth (social/viral).
Clarifying Questions:
Before deciding, I'd ask: What's our current new user churn rate vs. benchmark? What's Netflix's primary strategic priority for 2026? What's the engineering capacity in Q3?
Framework & Approach:
RICE scoring combined with strategic impact analysis:
Personalized Recommendations - Reach: High (all new users), Impact: High (directly reduces churn), Confidence: 80%, Effort: 4 months
Interactive Stories - Reach: Medium (subset of users), Impact: Medium (engagement lift), Confidence: 60%, Effort: 6 months
Party Watch - Reach: Low-Medium (social segment), Impact: Medium (viral potential), Confidence: 50%, Effort: 5 months
Recommendation: Prioritize Personalized Recommendations
Rationale:
Retention is foundational - acquiring users is 5-7x more expensive than retaining them
First 30 days are critical for subscriber LTV
Proven ROI path with existing ML infrastructure
Enables other features by building a stable user base
Clear, measurable impact
Key Success Metrics:
Day 7, Day 30, Day 90 retention rates
Time to first watch
Churn rate in first 90 days
Content discovery rate
LTV improvement
Data Needed:
Current churn curves for new users
Exit survey insights
A/B test results from previous recommendation improvements
CAC vs LTV gap analysis
Trade-offs:
We delay engagement differentiation (interactive stories) and social growth opportunities (party watch), these features require a retained user base to be effective. I'd propose testing party watch as a Q4 beta if capacity allows, as it requires less content creation overhead than interactive stories.
Alternative scenario: If data shows retention is healthy (>80% at Day 30), I'd pivot to interactive stories for differentiation
