User Story Format

"As a [persona], I want to [capability], so that [benefit]."

INVEST Criteria

Story Levels

• Epic: Large feature area (weeks-months)
• Feature: Specific capability (days-weeks)
• Story: Single piece of work (hours-days)
• Task: Technical subtask (hours)

When to Use

• Sprint planning
• Backlog refinement
• Requirements handoff
• Feature scoping
• Acceptance testing prep

Instructions

Step 1: Identify Source Document

Read from:

• PRD in 03-docs/
• Initiative in 03-docs/
• Requirements summary

Step 2: Extract Requirements

List all capabilities mentioned:

• Functional requirements
• Non-functional requirements
• User needs
• Business rules

Step 3: Generate Stories

For each capability:

### Story: [Title]
**As a** [persona],
**I want to** [capability],
**So that** [benefit].
 
**Priority**: P0/P1/P2
**Estimate**: [Story Points]
 
**Acceptance Criteria**:
-[ ] Given [context], when [action], then [result]
-[ ] Given [context], when [action], then [result]
 
**Notes**: [Additional context]

Group related stories under epics:

• Epic 1: [Name]
• Story 1.1
• Story 1.2

• [ ] Independent from other stories
• [ ] Negotiable in implementation
• [ ] Valuable to user/business
• [ ] Estimable by team
