What Makes This Skill Different

• Capacity math that aligns with reality: sprint capacity is based on velocity × availability factor, not hope.
• Acceptance criteria scaled by story size: minimum AC counts map to story points to avoid under-spec'ing large items.
• Weighted prioritization that stays consistent: value 40%, impact 30%, risk 15%, effort 15% keeps tradeoffs explicit.
• Systematic epic splitting techniques: five concrete split patterns prevent oversized stories.
• INVEST validation baked into workflows: every story includes a validation step, not just guidance.

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

Type	Template	Example
Feature	As a [persona], I want to [action] so that [benefit]	As a user, I want to filter search results so that I find items faster
Improvement	As a [persona], I need [capability] to [goal]	As a user, I need faster page loads to complete tasks without frustration
Bug Fix	As a [persona], I expect [behavior] when [condition]	As a user, I expect my cart to persist when I refresh the page
Enabler	As a developer, I need to [technical task] to enable [capability]	As a developer, I need to implement caching to enable instant search

Persona Reference

Persona	Typical Needs	Context
End User	Efficiency, simplicity, reliability	Daily feature usage
Administrator	Control, visibility, security	System management
Power User	Automation, customization, shortcuts	Expert workflows
New User	Guidance, learning, safety	Onboarding

---

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:

Category	Example
Happy Path	Given valid input, When submitted, Then success message displayed
Validation	Should reject input when required field is empty
Error Handling	Must show user-friendly message when API fails
Performance	Should complete operation within 2 seconds
Accessibility	Must be navigable via keyboard only

Minimum Criteria by Story Size

Story Points	Minimum AC Count
1-2	3-4 criteria
3-5	4-6 criteria
8	5-8 criteria
13+	Split the story

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

Splitting Techniques

Technique	When to Use	Example
By workflow step	Linear process	"Checkout" → "Add to cart" + "Enter payment" + "Confirm order"
By persona	Multiple user types	"Dashboard" → "Admin dashboard" + "User dashboard"
By data type	Multiple inputs	"Import" → "Import CSV" + "Import Excel"
By operation	CRUD functionality	"Manage users" → "Create" + "Edit" + "Delete"
Happy path first	Risk reduction	"Feature" → "Basic flow" + "Error handling" + "Edge cases"

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

Scenario	Factor
Full sprint, no PTO	1.0
One team member out 50%	0.9
Holiday during sprint	0.8
Multiple members out	0.7

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

Priority	Definition	Sprint Target
Critical	Blocking users, security, data loss	Immediate
High	Core functionality, key user needs	This sprint
Medium	Improvements, enhancements	Next 2-3 sprints
Low	Nice-to-have, minor improvements	Backlog

Prioritization Factors

Factor	Weight	Questions
Business Value	40%	Revenue impact? User demand? Strategic alignment?
User Impact	30%	How many users? How frequently used?
Risk/Dependencies	15%	Technical risk? External dependencies?
Effort	15%	Size? Complexity? Uncertainty?

INVEST Criteria Validation

Before adding to sprint, validate each story:

Criterion	Question	Pass If...
Independent	Can this be developed without other uncommitted stories?	No blocking dependencies
Negotiable	Is the implementation flexible?	Multiple approaches possible
Valuable	Does this deliver user or business value?	Clear benefit in "so that"
Estimable	Can the team estimate this?	Understood well enough to size
Small	Can this complete in one sprint?	≤8 story points
Testable	Can we verify this is done?	Clear acceptance criteria
