## Definition
|
||
|
||
WSJF 是 Scaled Agile Framework (SAFe) 中用于**排列工作优先级**的量化方法。通过将"延迟成本"（Cost of Delay）除以"工作规模"（Job Size），得到每单位工时的价值回报，优先做 WSJF 值最高的工作。
|
||
|
||
## Formula
|
||
|
||
```
|
||
WSJF = Cost of Delay (CoD) / Job Size
|
||
```
|
||
|
||
**Cost of Delay (CoD)** 由三部分构成：
|
||
- **Business Value**（业务价值）：对客户的直接经济影响
|
||
- **Time Criticality**（时间紧迫性）：推迟交付的价值损失
|
||
- **Risk Reduction / Opportunity Enablement**（风险降低 / 机会实现）
|
||
|
||
## Interpretation
|
||
|
||
| WSJF 值 | 优先级 | 含义 |
|
||
|---------|--------|------|
|
||
| 高 | 🔴 最高 | 价值高 + 工作量小，优先做 |
|
||
| 中 | 🟡 中等 | 价值与工作量平衡 |
|
||
| 低 | 🟢 低 | 价值低 + 工作量大，延后做 |
|
||
|
||
**核心理念**：`What we want to do is deliver the maximum value early back into the business for the least amount of effort.` — 以最小投入尽早交付最大价值。
