# Business Analyst

## Purpose
Provides expertise in requirements gathering, business process modeling, and translating stakeholder needs into actionable technical specifications. Bridges communication between business stakeholders and development teams.

## When to Use
- Gathering and documenting requirements
- Writing user stories and acceptance criteria
- Modeling business processes with BPMN
- Creating functional specifications
- Analyzing stakeholder needs
- Defining product requirements documents (PRDs)
- Mapping current vs future state processes

## Quick Start
**Invoke this skill when:**
- Gathering and documenting requirements
- Writing user stories and acceptance criteria
- Modeling business processes with BPMN
- Creating functional specifications
- Translating business needs to technical specs

**Do NOT invoke when:**
- Designing system architecture (use solution-architect)
- Managing project timeline and resources (use project-manager)
- Conducting user research (use ux-researcher)
- Defining product strategy (use product-manager)

## Decision Framework
```
Requirements Type:
├── New feature → User stories + acceptance criteria
├── Process improvement → AS-IS/TO-BE BPMN models
├── System integration → Interface specifications
├── Compliance need → Regulatory requirements matrix
└── Stakeholder request → Impact analysis + prioritization
```

## Core Workflows

### 1. Requirements Gathering
1. Identify all stakeholders
2. Conduct discovery interviews
3. Document current pain points
4. Define success metrics
5. Draft initial requirements
6. Validate with stakeholders
7. Prioritize using MoSCoW or similar

### 2. User Story Creation
1. Identify user personas
2. Map user journeys
3. Write stories in standard format
4. Define acceptance criteria (Given/When/Then)
5. Estimate complexity with team
6. Refine through backlog grooming

### 3. Business Process Modeling
1. Map current state (AS-IS) process
2. Identify bottlenecks and pain points
3. Design future state (TO-BE) process
4. Define transition requirements
5. Create RACI matrix for roles
6. Document process metrics

## Best Practices
- Use standard user story format: "As a [user], I want [goal], so that [benefit]"
- Write testable acceptance criteria
- Maintain requirements traceability matrix
- Validate requirements with real users
- Keep documentation living and updated
- Use visual models to communicate complex processes

## Anti-Patterns
| Anti-Pattern | Problem | Correct Approach |
|--------------|---------|------------------|
| Solution in requirements | Constrains implementation | Focus on the "what", not "how" |
| Missing acceptance criteria | Unclear definition of done | Every story needs testable criteria |
| No stakeholder validation | Building wrong thing | Regular stakeholder reviews |
| Waterfall requirements | Can't adapt to change | Iterative refinement |
| Technical jargon | Business can't validate | Use business language |
