# Requirements Prioritization Methods

## MoSCoW Method

### Must-have
- Product cannot launch without it
- Core value proposition
- Legal/compliance requirements

### Should-have
- Important but not critical
- Has workarounds available
- Can be deferred to next version

### Could-have
- Desirable features
- Enhance user experience
- Implement if resources permit

### Won't-have
- Not included in this version
- Explicitly excluded
- May be considered in the future

## Value-Complexity Matrix

| High Value Low Complexity | High Value High Complexity |
|---------------------------|----------------------------|
| **Quick Wins**            | **Major Projects**         |
| Prioritize immediately    | Plan carefully             |

| Low Value Low Complexity | Low Value High Complexity |
|--------------------------|---------------------------|
| **Fill-ins**             | **Avoid**                 |
| Do if time permits       | Do not implement          |

## RICE Scoring

```
RICE Score = (Reach × Impact × Confidence) / Effort
```

- **Reach**: Number of users affected (per quarter/month)
- **Impact**: Degree of impact (0.25=Minimal, 0.5=Low, 1=Medium, 2=High, 3=Massive)
- **Confidence**: Certainty level (100%=High, 80%=Medium, 50%=Low)
- **Effort**: Work required (person-months)

## Kano Model

### Basic Needs
- Essential features that must be met
- Absence causes extreme dissatisfaction
- Presence does not generate particular delight

### Performance Needs
- Better performance yields higher satisfaction
- Related to performance, speed, and quality

### Delighters
- Features that exceed expectations
- Bring surprise and delight
- Create competitive differentiation
