# Prioritization Quick Reference

## RICE Formula

```
RICE = (Reach × Impact × Confidence) ÷ Effort
```

| Factor | Type | Scale / Units |
|--------|------|---------------|
| Reach | Number | Users, events, or conversions per timeframe |
| Impact | 0.25–3 | 0.25 min, 0.5 low, 1 med, 2 high, 3 massive |
| Confidence | % | 50%, 80%, 100% |
| Effort | Person-months | Total team capacity |

**Higher RICE = higher priority.**

## MoSCoW Buckets

| Bucket | Meaning | Guideline |
|--------|----------|-----------|
| **M**ust | Launch blockers | ≤ 60% of scope |
| **S**hould | Important, not blocking | |
| **C**ould | Nice to have | If time permits |
| **W**on't | Out of scope | Capture for later |

## Impact Mapping Structure

```
Goal: [Business outcome]
├── Actor: [Who can help/block]
│   ├── Impact: [Behavior change needed]
│   │   ├── Deliverable: [What we build]
│   │   └── Deliverable: [...]
│   └── Impact: [...]
└── Actor: [...]
```

## Value vs Effort Matrix

| | Low Effort | High Effort |
|---|------------|-------------|
| **High Value** | Quick wins ✓ | Big bets |
| **Low Value** | Fill-ins | Avoid ✗ |

## Framework Comparison

| Use Case | Best Framework |
|----------|----------------|
| Ranked backlog, quantitative | RICE |
| Release scope, stakeholder alignment | MoSCoW |
| Goal alignment, assumption surfacing | Impact Mapping |
| Quick triage | Value/Effort |

## Communicating Priorities

1. **Show the model** — Don't hide; share how you scored
2. **Make inputs editable** — Disagreement? Change inputs, re-run
3. **Capture "Won't"** — Explicit out-of-scope prevents surprises
4. **Revisit often** — New info → new scores

## RICE Example

| Initiative | R | I | C | E | RICE |
|------------|---|---|---|---|------|
| Dark mode | 10k | 0.5 | 100% | 1 | 5,000 |
| Search | 8k | 2 | 80% | 3 | 4,267 |
| Export | 2k | 1 | 100% | 0.5 | 4,000 |
