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

TypeTemplateExample
FeatureAs a [persona], I want to [action] so that [benefit]As a user, I want to filter search results so that I find items faster
ImprovementAs a [persona], I need [capability] to [goal]As a user, I need faster page loads to complete tasks without frustration
Bug FixAs a [persona], I expect [behavior] when [condition]As a user, I expect my cart to persist when I refresh the page
EnablerAs a developer, I need to [technical task] to enable [capability]As a developer, I need to implement caching to enable instant search

Persona Reference

PersonaTypical NeedsContext
End UserEfficiency, simplicity, reliabilityDaily feature usage
AdministratorControl, visibility, securitySystem management
Power UserAutomation, customization, shortcutsExpert workflows
New UserGuidance, learning, safetyOnboarding

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:

CategoryExample
Happy PathGiven valid input, When submitted, Then success message displayed
ValidationShould reject input when required field is empty
Error HandlingMust show user-friendly message when API fails
PerformanceShould complete operation within 2 seconds
AccessibilityMust be navigable via keyboard only

Minimum Criteria by Story Size

Story PointsMinimum AC Count
1-23-4 criteria
3-54-6 criteria
85-8 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

TechniqueWhen to UseExample
By workflow stepLinear process"Checkout" → "Add to cart" + "Enter payment" + "Confirm order"
By personaMultiple user types"Dashboard" → "Admin dashboard" + "User dashboard"
By data typeMultiple inputs"Import" → "Import CSV" + "Import Excel"
By operationCRUD functionality"Manage users" → "Create" + "Edit" + "Delete"
Happy path firstRisk 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

ScenarioFactor
Full sprint, no PTO1.0
One team member out 50%0.9
Holiday during sprint0.8
Multiple members out0.7

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

PriorityDefinitionSprint Target
CriticalBlocking users, security, data lossImmediate
HighCore functionality, key user needsThis sprint
MediumImprovements, enhancementsNext 2-3 sprints
LowNice-to-have, minor improvementsBacklog

Prioritization Factors

FactorWeightQuestions
Business Value40%Revenue impact? User demand? Strategic alignment?
User Impact30%How many users? How frequently used?
Risk/Dependencies15%Technical risk? External dependencies?
Effort15%Size? Complexity? Uncertainty?

INVEST Criteria Validation

Before adding to sprint, validate each story:

CriterionQuestionPass If...
IndependentCan this be developed without other uncommitted stories?No blocking dependencies
NegotiableIs the implementation flexible?Multiple approaches possible
ValuableDoes this deliver user or business value?Clear benefit in "so that"
EstimableCan the team estimate this?Understood well enough to size
SmallCan this complete in one sprint?≤8 story points
TestableCan we verify this is done?Clear acceptance criteria

When the user wants to plan, design, or implement an A/B test or experiment, or build a growth experimentation program. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," "hypothesis," "should I test this," "which version is better," "test two versions," "statistical significance," "how long should I run this test," "growth experiments," "experiment velocity," "experiment backlog," "ICE score," "experimentation program," or "experiment playbook." Use this whenever someone is comparing two approaches and wants to measure which performs better, or when they want to build a systematic experimentation practice. For tracking implementation, see analytics. For page-level conversion optimization, see cro.

When the user wants to generate, iterate, or scale ad creative — headlines, descriptions, primary text, or full ad variations — for any paid advertising platform. Also use when the user mentions 'ad copy variations,' 'ad creative,' 'generate headlines,' 'RSA headlines,' 'bulk ad copy,' 'ad iterations,' 'creative testing,' 'ad performance optimization,' 'write me some ads,' 'Facebook ad copy,' 'Google ad headlines,' 'LinkedIn ad text,' or 'I need more ad variations.' Use this whenever someone needs to produce ad copy at scale or iterate on existing ads. For campaign strategy and targeting, see ads. For landing page copy, see copywriting.
