Churn мобильной игры удвоился за неделю: диагностика

Это crisis scenario. Требует систематический approach.

Шаг 1: Urgency assessment (5 минут)

Что случилось за последнюю неделю?

• New version launch?
• Server downtime?
• Change in game mechanics?
• New competitors?
• Negative media coverage?

Check:

• Version history (когда последний update)
• Server logs (были ли issues)
• Social media (что люди говорят)
• News (конкуренты, PR)

Шаг 2: Confirm the data (15 минут)

Убедиться, что это реально происходит

Вопросы:

• D-0 (день 7 дней назад): какой был churn?
• D-1 через D-6: был ли градуальный рост или sudden spike?
• Это все users или specific cohort (new vs old, certain regions)?
• Is это churn (stop playing) или crash (game doesn't work)?

Check:

• Analytics dashboard
• Cohort analysis (which users are leaving)
• If sudden: probably update or server issue
• If gradual: probably gameplay issue

Шаг 3: Determine the timeline (10 минут)

When exactly did churn spike?

• Monday midnight? (probably deploy)
• Wednesday during business hours? (probably event or competitor move)
• Different times in different regions? (might be regional server issue)

This narrows down root causes.

Scenario A: Churn spiked день 7 дней назад, и stable high с тех пор → Probably change (update, feature, bug) introduced → People left и не returned

Scenario B: Churn gradually increased over 7 дней → Probably something external (competitor launched, trend changed) → Or slow degradation (server getting slower)

Шаг 4: Segment the leavers (20 минут)

Who is leaving?

• New players (first week users)? Retention issue
• Old players (retained 6+ months)? Major problem (loyalty broken)
• Specific region? Localization or server issue
• Specific device (Android/iOS)? Platform issue
• Specific level? Difficulty spike
• Specific monetization behavior? (F2P vs paying users)

Most important insight:

• If old players leaving: CRISIS (game-breaking bug or feature)
• If only new players: New player experience issue

Шаг 5: Check recent changes (30 минут)

Engineering side:

• What code changed in last version?
• Are there critical bugs reported in logs?
• Server performance degradation?
• Database issues?
• API failures?

Product side:

• New feature that broke something?
• Difficulty increase?
• Economy balance change (too expensive)?
• Removed popular feature?
• UI/UX change that confused users?

Monetization:

• Ad increase?
• Paywall changes?
• IAP pricing change?

External:

• Competitor launched?
• Influencer reviewed negatively?
• App Store algorithm change?

Шаг 6: User feedback analysis (20 минут)

What are users saying?

• App Store reviews (new 1-star reviews)
• Twitter, Reddit, Discord
• In-game feedback
• Customer support tickets

Common complaints reveal pattern:

• "Unplayable" / "Too buggy" → bug
• "Too expensive" → monetization
• "Boring" / "No content" → gameplay
• "Can't progress" → difficulty spike
• "Ads everywhere" → user experience

Шаг 7: Run rapid experiments (1-4 часа)

Manual testing:

• Fresh install: how easy to get engaged?
• Play through: any crashes, performance issues?
• Test monetization: does paywall feel fair?
• Compare old version (if possible): what's different?

Data experiments (if analytics tools available):

• Session length: Are sessions shorter (gameplay issue)?
• Crash rate: Any crashes in last update?
• Time to first purchase: Is monetization blocked?
• Specific level abandonment: Which level loses most players?

Шаг 8: Hypotheses & prioritization

Most likely causes (prioritized):

1. Critical bug introduced in last update (80% probability)

   • Symptoms: sudden spike, old players leaving, crash rate up
   • Solution: rollback + hotfix
   • Time to fix: hours

2. Difficulty balance issue (60% probability)

   • Symptoms: new players leaving after level X, session length down
   • Solution: adjust game balance
   • Time to fix: 1-2 days

3. Monetization became too aggressive (40% probability)

   • Symptoms: new players leaving early, F2P retention down
   • Solution: adjust ad frequency or paywall
   • Time to fix: 1 day

4. Competitor launched something better (30% probability)

   • Symptoms: all cohorts affected equally, gradual migration
   • Solution: improve game or marketing
   • Time to fix: weeks

5. Server performance degradation (20% probability)

   • Symptoms: crashes, lag, timeouts
   • Solution: scale infrastructure or optimize queries
   • Time to fix: hours to days

Шаг 9: Action plan (based on evidence)

If #1 (bug):

• Emergency meeting with engineering
• Rollback last version if critical
• Or ship hotfix within hours
• Monitor churn in real-time

If #2 (difficulty):

• Reduce difficulty on level X
• Monitor churn rate
• A/B test different difficulty levels

If #3 (monetization):

• Reduce ad frequency
• Move paywall back
• Monitor conversion vs churn trade-off

If #4 (competition):

• Analyze competitor game
• Plan content update (2-4 weeks)
• Improve marketing (1 week)

Шаг 10: Communication & monitoring

Immediately:

• Notify CEO/leadership (crisis mode)
• Prepare status updates (hourly if critical)
• Assign owner (engineering? Product?)
• Create war room (all relevant people)

Monitoring:

• Track churn every hour
• Watch for secondary effects (retention, DAU)
• Gather user feedback continuously
• Prepare rollback plan if things worsen

Communication:

• Transparent to users (if major issue: "We're aware of issue X")
• Regular updates to team
• Post-mortem once resolved

В interview

"Если churn удвоился за неделю:

Step 1: Confirm data (это реально? все cohorts?) Step 2: Timeline (sudden spike vs gradual? when exactly?) Step 3: Segment (новые игроки уходят или старые?) Step 4: Recent changes (update? feature? server issue?) Step 5: User feedback (что люди говорят?) Step 6: Experiments (manually test, run analytics checks) Step 7: Hypotheses (что most likely?) Step 8: Action (bug → rollback, balance → adjust, monetization → soften)

Most likely:

1. Critical bug (sudden spike, old players leave)
2. Difficulty issue (new players abandon at level X)
3. Monetization too aggressive (paywall/ads)

I would:

• Get on emergency call with engineering + analytics
• Identify root cause within 2 hours
• Action plan ready within 4 hours
• Monitor churn in real-time during fix
• Post-mortem once stabilized

Key: move fast, diagnose systematically, monitor continuously."
