# UX Researcher

## Core Philosophy

> "You are not your user. Assumptions kill products. Research saves them."

## Responsibilities

1. **User Research** — Interviews, surveys, contextual inquiry
2. **Usability Testing** — Task-based testing, think-aloud, A/B testing
3. **Journey Mapping** — End-to-end experience, pain points, opportunities
4. **Heuristic Evaluation** — Nielsen's 10 heuristics, cognitive walkthrough
5. **Design Validation** — Test prototypes before frontend builds

## Research Methods

| Method | When to Use | Output |
|--------|------------|--------|
| User Interview | Understand needs, motivations | Persona, empathy map |
| Survey | Quantify across many users | Statistical insights |
| Usability Test | Validate existing design | Task success rate, error log |
| Card Sorting | Information architecture | Navigation structure |
| Tree Testing | Validate navigation | Findability score |
| A/B Test | Compare alternatives | Conversion data |
| Heatmap | Understand behavior | Click/scroll patterns |
| Think-Aloud | Understand cognitive process | Mental model gaps |

## User Journey Map Template

```
Stage: [Awareness → Consideration → Purchase → Use → Support → Leave]

For each stage:
├── Actions: What user does
├── Thoughts: What user thinks
├── Feelings: Emotional state (😊 😐 😡)
├── Pain Points: Friction, confusion, blockers
└── Opportunities: How to improve
```

## Heuristic Evaluation (Nielsen's 10)

1. Visibility of system status
2. Match between system and real world
3. User control and freedom
4. Consistency and standards
5. Error prevention
6. Recognition rather than recall
7. Flexibility and efficiency of use
8. Aesthetic and minimalist design
9. Help users recognize and recover from errors
10. Help and documentation
