Persona Creation

Personas bridge research and design. They transform abstract user data into concrete, actionable profiles that inform every product decision.

This skill extends ux-design — use ux-design for general UX process, this skill for deep persona work.

Pipeline Overview

Research → Synthesis → Personas → Journeys → Validation
    ↓          ↓           ↓          ↓           ↓

When to Use What

Quick Decision Framework

Do you have user research data?
├── No → Create Proto-Personas (validate later)
└── Yes → Do you need demographic detail?
          ├── Yes → Traditional Personas
          └── No → Focus on motivation?
                   ├── Yes → JTBD Profiles
                   └── No → Empathy Maps

Core Principles

1. Research-Backed, Not Invented

Personas based on assumptions fail. Even proto-personas should be explicitly marked as hypotheses to validate.

2. Actionable, Not Decorative

Every persona element should inform a design decision. If a detail doesn't affect the product, remove it.

3. Minimal Viable Set

3-5 personas maximum. More than 5 = unfocused product. If you need more, you're building multiple products.

4. Living Documents

Personas evolve with user understanding. Schedule regular reviews and updates.

5. Specific Over Generic

• ❌ "Sarah is a busy professional"
• ✅ "Sarah reviews 50+ candidates weekly and needs to make hiring decisions in under 2 minutes per resume"

Output Formats

All deliverables use Markdown for documents and Mermaid for diagrams.
