# Analysis — Design Token Migration

## Topic
Migration from legacy SCSS variables to a unified JSON-based design token system (Style Dictionary) across web, iOS, and Android platforms.

## Key Themes
1. **Phased rollout** — 4 clear phases spanning Feb 2026 → Jul 2026
2. **Cross-platform unification** — one source of truth for web, iOS, Android
3. **Measurable progress** — strong metrics showing adoption, performance, and quality gains
4. **Automation-first** — codemods, CI pipelines, linter enforcement

## Data Points
- 847 total SCSS variables cataloged across 12 repos
- 623/847 auto-migrated via codemod (74% web adoption)
- Theme switch time improved from 3.2s → 0.4s
- Design-dev handoff errors dropped from 14/sprint → 5/sprint
- Unique color values reduced from 312 → 89 (target: ≤48)
- Visual regression incidents dropped from 6/month → 1/month

## Relationships
- Phases are sequential with dependencies (Phase 1 feeds Phase 2, etc.)
- Metrics track across baseline → current → target
- Phase 2 (current) is the focal point — mobile rollout approved for Phase 3

## Target Audience
All-hands meeting attendees — engineering leadership, product, design. Need high-level understanding of progress and plan, not implementation details.

## Layout × Style Recommendation
Content mixes a 4-phase sequential timeline with a metrics dashboard. Portrait orientation for slide. Best fits:
1. **`bento-grid` + `corporate-memphis`** — hero module for title/status, feature modules for each phase, detail modules for key metrics. Clean, vibrant, all-hands appropriate.
2. **`linear-progression` + `corporate-memphis`** — strong timeline narrative but harder to incorporate the metrics table elegantly.
3. **`bento-grid` + `craft-handmade`** — warm and approachable but may feel too casual for a leadership all-hands.
