## Definition
RICE 是用于客观优先级排序的量化框架，通过四个维度计算分数：Reach（触达）、Impact（影响）、Confidence（信心）、Effort（努力）。

## Formula
**RICE Score = (R × I × C) ÷ E**

| Factor | Scale | Description |
|--------|-------|-------------|
| Reach | 用户数/季度 | 多少人受影响 |
| Impact | 0.25, 0.5, 1, 2, 3 | 对指标的影响倍数 |
| Confidence | 百分比 | 估计的信心水平 |
| Effort | 人力月数 | 需要多少时间 |

## Example Calculation
| Factor | Value | Notes |
|--------|-------|-------|
| Reach | 10,000 users/quarter | Source: analytics |
| Impact | 0.5 | half of 1x |
| Confidence | 80% | Based on: interviews |
| Effort | 4 person-months | M t-shirt |
| **RICE Score** | **100** | |

## Use Case
- 跨多个机会客观排序
- 支撑 build/defer/kill 决策对话
- 替代直觉式优先级排序

## Limitation
- 估算性质，结果应作为讨论起点而非绝对值
- 不捕捉战略重要性或风险
- 需要定期重新评估
