## About

# Automated Aha Moment Engineering

## Core Principles

1. **Aha is Causation Not Correlation**: The Aha Moment must be a causal relationship between behavior and retention, not merely a correlation
2. **Reach Rate Determines the Ceiling**: No matter how strong an Aha Moment is, if the reach rate is low it cannot scale; the reach path must be optimized simultaneously
3. **Shortest Path First**: The shorter the path from registration to Aha Moment, the higher the activation rate

## Input

| Input Item | Type | Required | Source | Description |
|--------|------|------|------|------|
| Retention data | object | Yes | output/pm-metrics-ops/analysis-retention/retention_analysis.json | D1/D7/D30 retention rates |
| User behavior data | object | Yes | User provided | Event logs, behavior sequences |
| User segment data | object | ○ | User provided | User segment data |

## Aha Moment Definition

The Aha Moment is the critical moment when a user first experiences the core value of the product. After completing this behavior, users are more likely to retain long-term and become active users.

**Aha Moment = Specific Behavior + Specific Time Window + Retention Lift Effect**

## Execution Steps

### Step 1: Aha Moment Candidate Search [Core]

#### Candidate Behavior Enumeration
Scan all user behaviors to find those highly correlated with retention:

1. **Behavior Type Classification**:
   - Core feature usage
   - Key path completion
   - Social interaction behaviors
   - Content creation behaviors
   - Settings configuration behaviors

2. **Time Window Analysis**:
   - Within 1 hour of registration
   - Within 24 hours of registration
   - Within 7 days of registration

3. **Correlation Calculation**:
   ```
   Correlation = Degree of correlation between user performing behavior and retention
   Lift = Retention rate of users who performed the behavior - Retention rate of users who did not
   ```

#### Candidate Filtering Criteria
- Correlation ≥ 0.5
- Reach rate ≥ 10%
- Retention lift ≥ 15%

### Step 2: Reach Rate Measurement [Core]

Analyze the actual reach of each candidate Aha Moment:

| Metric | Description |
|------|------|
| Overall reach rate | Proportion of users who reached this behavior out of total registered users |
| Time distribution | Time distribution of users reaching this behavior |
| Path analysis | User path from registration to this behavior |
| Drop-off nodes | Drop-off points before users reach this behavior |

### Step 3: Shortest Path Identification [Core]

Analyze how to get users to the Aha Moment fastest:

1. **Path analysis**: Identify typical paths from registration to Aha Moment
2. **Friction identification**: Find friction points and drop-off points in the path
3. **Optimization recommendations**: Design shorter reach paths

### Step 4: Onboarding Optimization Recommendations [Deep]

Based on Aha Moment analysis, generate Onboarding optimization recommendations:

#### Direct Guidance Strategy
- Directly guide users to complete the Aha Moment behavior in the Onboarding flow
- Design a "one-click experience core feature" shortcut path

#### Incentive Strategy
- Provide rewards for users who complete the Aha Moment behavior
- Lower the barrier to completing the Aha Moment

#### Education Strategy
- Strengthen the value demonstration of the Aha Moment
- Provide value preview before reaching the Aha Moment

### Output Depth Tiering

| Depth Level | Output Scope | Description |
|----------|----------|------|
| quick | Aha moment and activation path | Core conclusions + minimum viable output |
| standard | Full output (current default) | Complete output including all Step outputs |
| deep | Full strategy + Aha moment quantitative validation + Activation path optimization + Activation funnel deep analysis | Full output + extended analysis + deep inference |

   - Correlation: 0.82
   - Reach rate: 35%
   - Retention lift: +42%
   - Recommendation: Optimize project creation flow, lower creation barrier

2. "First share content with friends"
   - Correlation: 0.65

## Degradation Strategy

### Upstream File Missing Degradation Plan

| Missing Upstream Input | Degradation Plan | Output Impact | Data Acquisition Instructions |
|----------|----------|----------|------------|
| Retention data missing | User provides user behavior list → Infer Aha Moment candidates | Aha Moment based on inference rather than data validation | Request user to provide retention rate difference data for users with different behaviors |
| Behavior data missing | User provides user behavior list → Infer Aha Moment candidates | Cannot perform behavior-retention correlation analysis | Request user to provide user behavior event logs (including event name, timestamp, user ID) |
| Both retention data and behavior data missing | User provides user behavior list → Infer Aha Moment candidates | Output Aha Moment candidate list, marked as "awaiting data validation" | Request user to provide user behavior list and retention rate data |
| User segment data missing | Skip segment comparison analysis, output overall Aha Moment only | Cannot identify differentiated Aha Moments for different user groups | Request user to provide user segment tags and behavioral characteristics per group |

### Data Acquisition Instructions

When upstream files are missing, the user needs to provide the following information to support degraded generation:
- **User Behavior List**: Core behaviors users can perform in the product
- **Retention Rate Data** (optional): Retention rate differences for users with different behaviors
- **New User Typical Path** (optional): Most common action sequences for new users

## Upstream Change Response

### Upstream Change Impact Table

| Upstream Source | Change Type | Impact Scope | Response Action |
|----------|----------|----------|----------|
| analysis-retention | Retention metric definition change | Correlation calculation and retention lift assessment | Recalculate correlation and retention lift using new definition |
| User provided - Behavior data | Event definition change | Candidate behavior enumeration and path analysis | Update behavior classification, re-search candidates |
| User provided - Segment data | Segment dimension change | Segment-level Aha Moment identification | Re-identify segment Aha using new dimensions |

### Downstream Notification Mechanism Table

| Downstream Consumer | Notification Condition | Notification Method | Notification Content |
|------------|----------|----------|----------|
| activation-onboarding | Primary Aha Moment change | Write to output file | New Aha behavior, reach rate, and guidance path |
| activation-orchestrator | Aha Moment identification completed | Output file updated | Aha identification completion status and key conclusions |

## Notes

- Aha Moments may change as the product iterates and should be periodically re-evaluated
- Different user segments may have different Aha Moments
- Aha Moment optimization requires balancing reach rate and retention lift
