#### 9. Analytics and Metrics

```markdown
### Key Performance Indicators

**Product KPIs:**
- Acquisition: [New users/month]
- Activation: [% completing onboarding]
- Engagement: [DAU, session length]
- Retention: [Day 7, Day 30]
- Revenue: [MRR, ARPU]
- Referral: [NPS, viral coefficient]

**Success Metrics:**
| Metric | Current | Target | Timeline |
|--------|---------|--------|----------|
| User Adoption | 0 | 10K users | 3 months |
| Activation Rate | - | 40% | Launch+30d |
| DAU/MAU | - | 25% | Launch+90d |
| NPS | - | 40+ | Launch+90d |

### Event Tracking Plan

| Event Name | Description | Properties | Priority |
|------------|-------------|------------|----------|
| user_signup | User completes registration | source, plan | P0 |
| feature_used | User activates key feature | feature_name, duration | P0 |
| conversion | User upgrades to paid | plan, amount | P0 |
| error_occurred | System error | error_type, page | P1 |

### A/B Testing

**Test 1: [Onboarding Flow]**
- Hypothesis: [Simplified onboarding will increase activation by 20%]
