## Aliases
|
||||
- RICE
|
||||
- RICE Score
|
||||
- RICE Framework
|
||||
|
||||
## Definition
|
||||
RICE 优先级评分框架 —— 一个量化的四因子需求优先级评估模型,通过公式 `(R × I × C) ÷ E` 计算综合得分,以数据支撑优先级排序决策。
|
||||
|
||||
## Formula
|
||||
|
||||
| 因子 | 名称 | 定义 | 典型单位/范围 |
|
||||
|------|------|------|--------------|
|
||||
| **R** | Reach(触达) | 该功能一个季度内能影响多少用户 | 用户数/季度 |
|
||||
| **I** | Impact(影响力) | 对单个用户的影响力 | 0.25 / 0.5 / 1 / 2 / 3 |
|
||||
| **C** | Confidence(置信度) | 对假设的置信程度 | 百分比(50%–100%) |
|
||||
| **E** | Effort(工作量) | 完成所需的人力月数 | 人力月 |
|
||||
|
||||
**RICE Score = (R × I × C) ÷ E**
|
||||
|
||||
## Decision Threshold
|
||||
- 分数越高优先级越高
|
||||
- 通常与团队容量(capacity)结合,决定一个季度内可交付的数量
|
||||
- 分数需附带置信区间和敏感性分析
|
||||
|
||||
## Key Principles
|
||||
- **数据 + 判断结合** —— 数字提供框架,最终决策需要产品判断
|
||||
- **量化不确定性** —— C 因子显式记录假设的置信程度
|
||||
- **努力量化** —— 防止高影响力但无限工作量的小时级陷阱
|
||||
|
||||
## Usage
|
||||
由 [[Product Manager Agent]] 在 [[Opportunity Assessment]] 文档中使用,也用于 [[Product Roadmap (Now/Next/Later)]] 中的需求排序。
