User Story Generation Workflow

Create INVEST-compliant user stories from requirements:

1. Identify the persona (who benefits from this feature)
2. Define the action or capability needed
3. Articulate the benefit or value delivered
4. Write acceptance criteria using Given-When-Then
5. Estimate story points using Fibonacci scale
6. Validate against INVEST criteria
7. Add to backlog with priority
8. Validation: Story passes all INVEST criteria; acceptance criteria are testable

User Story Template

As a [persona],
I want to [action/capability],
So that [benefit/value].

Example:

As a marketing manager,
I want to export campaign reports to PDF,
So that I can share results with stakeholders who don't have system access.

Story Types

Persona Reference

Acceptance Criteria Patterns

Write testable acceptance criteria using Given-When-Then format.

Given-When-Then Template

Given [precondition/context],
When [action/trigger],
Then [expected outcome].

Examples:

Given the user is logged in with valid credentials,
When they click the "Export" button,
Then a PDF download starts within 2 seconds.

Given the user has entered an invalid email format,
When they submit the registration form,
Then an inline error message displays "Please enter a valid email address."

Given the shopping cart contains items,
When the user refreshes the browser,
Then the cart contents remain unchanged.

Acceptance Criteria Checklist

Each story should include criteria for:

Minimum Criteria by Story Size

See references/user-story-templates.md for complete template library.

Epic Breakdown Workflow

Break epics into deliverable sprint-sized stories:

1. Define epic scope and success criteria
2. Identify all personas affected by the epic
3. List all capabilities needed for each persona
4. Group capabilities into logical stories
5. Validate each story is ≤8 points
6. Identify dependencies between stories
7. Sequence stories for incremental delivery
8. Validation: Each story delivers standalone value; total stories cover epic scope

Story Splitting Decision Logic

Apply these rules in order. Use the first rule that fits the story:

Split Output Format

For each split, document:

## Original Story
As a [persona], I want to [action] so that [benefit].
Points: 13 | Status: Too large for sprint

## Suggested Splits

### Split 1: By Workflow Steps
- **Story A:** As a [persona], I want to [step 1] so that [partial benefit].
  Points: 5 | Independently valuable: Yes
- **Story B:** As a [persona], I want to [step 2] so that [remaining benefit].
  Points: 5 | Independently valuable: Yes

### Risks & Tradeoffs
- [What coupling exists between the split stories]
- [What is lost by delivering them separately]

### Implementation Order
1. Story A (foundation) → 2. Story B (builds on A)

Splitting Techniques (Quick Reference)

Epic Example

Epic: User Dashboard

Breakdown:

Epic: User Dashboard (34 points total)
├── US-001: View key metrics (5 pts) - End User
├── US-002: Customize layout (5 pts) - Power User
├── US-003: Export data to CSV (3 pts) - End User
├── US-004: Share with team (5 pts) - End User
├── US-005: Set up alerts (5 pts) - Power User
├── US-006: Filter by date range (3 pts) - End User
├── US-007: Admin overview (5 pts) - Admin
└── US-008: Enable caching (3 pts) - Enabler

Sprint Planning Workflow

Plan sprint capacity and select stories:

1. Calculate team capacity (velocity × availability)
2. Review sprint goal with stakeholders
3. Select stories from prioritized backlog
4. Fill to 80-85% of capacity (committed)
5. Add stretch goals (10-15% additional)
6. Identify dependencies and risks
7. Break complex stories into tasks
8. Validation: Committed points ≤85% capacity; all stories have acceptance criteria

Capacity Calculation

Sprint Capacity = Average Velocity × Availability Factor

Example:
Average Velocity: 30 points
Team availability: 90% (one member partially out)
Adjusted Capacity: 27 points

Committed: 23 points (85% of 27)
Stretch: 4 points (15% of 27)

Availability Factors

Sprint Loading Template

Sprint Capacity: 27 points
Sprint Goal: [Clear, measurable objective]

COMMITTED (23 points):
[H] US-001: User dashboard (5 pts)
[H] US-002: Export feature (3 pts)
[H] US-003: Search filter (5 pts)
[M] US-004: Settings page (5 pts)
[M] US-005: Help tooltips (3 pts)
[L] US-006: Theme options (2 pts)

STRETCH (4 points):
[L] US-007: Sort options (2 pts)
[L] US-008: Print view (2 pts)

See references/sprint-planning-guide.md for complete planning procedures.

Backlog Prioritization

Prioritize backlog using value and effort assessment.

Priority Levels

Prioritization Factors

INVEST Criteria Validation

Before adding to sprint, validate each story:

Reference Documentation

• Standard story formats by type (feature, improvement, bug fix, enabler)
• Acceptance criteria patterns (Given-When-Then, Should/Must/Can)
• INVEST criteria validation checklist
• Story point estimation guide (Fibonacci scale)
• Common story antipatterns and fixes
• Story splitting techniques

Sprint Planning Guide

• Backlog prioritization framework (WSJF)
• Sprint ceremony guides (standup, review, retro)
• Velocity tracking and burndown patterns
• Definition of Done checklist
• Sprint metrics and targets

Tools

User Story Generator

# Generate stories from sample epic

Troubleshooting

Success Criteria

Scope & Limitations

In scope:

• User story generation with INVEST validation
• Acceptance criteria in Given-When-Then format
• Sprint planning with capacity-based loading
• Epic breakdown into sprint-sized stories
• Backlog prioritization frameworks (WSJF, value/effort)
• Velocity tracking and sprint metrics
• Definition of Done enforcement

Out of scope:

• Jira/Linear ticket creation (use JSON export with their APIs)
• Burndown chart visualization (use project management tool dashboards)
• Team member assignment and capacity by individual
• Cross-team dependency management (use program-level tools)
• Release planning beyond quarterly horizon
• Automated acceptance test generation (see engineering skills)
