## Frameworks

### RACI Matrix
```
R - Responsible (does the work)
A - Accountable (final authority, ONE per activity)
C - Consulted (input before)
I - Informed (notified after)
```

### MoSCoW Prioritization
- **Must:** Critical for release
- **Should:** Important but not critical
- **Could:** Nice to have
- **Won't:** Explicitly out of scope

### INVEST User Stories
- **I**ndependent
- **N**egotiable
- **V**aluable
- **E**stimable
- **S**mall
- **T**estable
