+# Decision Framework
+
+## The First Questions
+
+### 1. Purpose?
+
+| Purpose | Approach | Priority |
+|---------|----------|----------|
+| Draw attention | Scale, color, pulse | Responsiveness |
+| Guide sequence | Stagger, directional flow | Clarity |
+| Provide feedback | Immediate response | Speed |
+| Create atmosphere | Subtle, continuous | Subtlety |
+| Explain relationship | Position, connection | Legibility |
+| Celebrate/reward | Overshoot, particles | Delight |
+
+### 2. Audience?
+- Stressed → calm motion; Browsing → richer motion
+- Task-focused → fast, minimal; Exploring → can be dramatic
+- Seen 100x/day → fast, subtle; Seen once → can be dramatic
+
+### 3. Context?
+- Busy layout → simpler motion; Empty → can be dramatic
+- Other animations active → coordinate or stagger
+- Small container → small motion
+
+## 4-Level Decision Hierarchy
+
+### Level 1: Motion Category
+
+| Category | When |
+|----------|------|
+| Revealing | Content appearing |
+| Concealing | Content disappearing |
+| Transitioning | Between states/views |
+| Emphasizing | Drawing attention |
+| Responding | Reacting to interaction |
+| Ambient | Background atmosphere |
+
+### Level 2: Motion Personality
+Match to brand. See [motion-personality.md](motion-personality.md).
+
+### Level 3: Motion Direction
+
+| Direction | Communicates |
+|-----------|-------------|
+| Upward | Growth, aspiration |
+| Downward | Settling, completion |
+| Leftward | Regression, departure |
+| Rightward | Progression, arrival |
+| Outward (scale up) | Importance, emergence |
+| Inward (scale down) | Dismissal, removal |
+| Center-seeking | Focus, convergence |
+| Center-fleeing | Distribution, release |
+
+### Level 4: Implementation Properties
+Choose animated properties. See [property-selection.md](../reference/property-selection.md).
+
+## Decision Quick-Path
+
+```
+1. PURPOSE → What does this motion DO?
+   ├── Feedback → short, ease-out, minimal
+   ├── Entrance → ease-out, personality-matched
+   ├── Exit → ease-in, 70% of entrance
+   ├── Emphasis → scale or color pulse
+   └── Ambient → slow, continuous, sine
+
+2. PERSONALITY → Match keywords
+   ├── Fun/bouncy → Playful
+   ├── Elegant/luxury → Premium
+   ├── Clean/professional → Corporate
+   └── Bold/dynamic → Energetic
+
+3. PROPERTIES → Minimum needed (two = sweet spot)
+
+4. TIMING → Check duration table, adjust for distance/weight
+
+5. EASING → Entering=ease-out, Leaving=ease-in, On-screen=ease-in-out, Looping=sine
+```
+
+## Evaluation Before Delivery
+
+| Check | Question |
+|-------|----------|
+| Purpose | Clear function? |
+| Personality | Matches brand/context? |
+| Repetition | Fine on 100th viewing? |
+| Attention | Respects viewer's focus? |
+| Hierarchy | Reinforces importance? |
+| Layers | Primary + secondary + ambient? |
+| Timing | Duration appropriate? |
