## Definition
RICE Scoring 是一种四维定量功能优先级排序框架,通过将每个功能的影响力转换为可比较的数值分数,消除团队优先级争论。
## Formula
```
RICE Score = (Reach × Impact × Confidence) / Effort
```
| 维度 | 定义 | 常见取值范围 |
|------|------|-------------|
| **Reach**(触达) | 该功能在第一个季度内能影响多少用户 | 110,000用户数 |
| **Impact**(影响) | 该功能对单个用户的影响力 | 3=massive, 2=high, 1=medium, 0.5=low, 0.25=minimal |
| **Confidence**(信心) | 对上述估算的信心程度 | 100%=high, 80%=medium, 50%=low |
| **Effort**(工作量) | 所需人月数(跨整个团队) | 0.520人月 |
## 应用场景
- **[[Phase 1 Strategy]]**Sprint Prioritizer 使用 RICE 评分对 Phase 1 产出的任务列表进行排序
- **[[scenario-startup-mvp]]**Week 1 快速发现阶段使用 RICE 评分 backlog
- 适用于 Sprint Planning、Product Roadmap 排序、技术债务优先级决策
## 示例
| 功能 | Reach | Impact | Confidence | Effort | RICE Score |
|------|-------|--------|-----------|-------|------------|
| 用户注册优化 | 5000 | 2 | 100% | 2 | 5000 |
| 支付流程简化 | 2000 | 3 | 80% | 4 | 1200 |
| 暗模式支持 | 3000 | 1 | 50% | 3 | 500 |
## 与 MoSCoW 的关系
RICE 分数高 ≠ Must-Have。MoSCoW 分类RICE分数 + 战略/合规考量)决定是否纳入当前 SprintRICE 仅排序在 MoSCoW Must/Should/Could 中的条目。
