User Story Generation Workflow
Create INVEST-compliant user stories from requirements:
- Identify the persona (who benefits from this feature)
- Define the action or capability needed
- Articulate the benefit or value delivered
- Write acceptance criteria using Given-When-Then
- Estimate story points using Fibonacci scale
- Validate against INVEST criteria
- Add to backlog with priority
- 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:
- Define epic scope and success criteria
- Identify all personas affected by the epic
- List all capabilities needed for each persona
- Group capabilities into logical stories
- Validate each story is ≤8 points
- Identify dependencies between stories
- Sequence stories for incremental delivery
- 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:
- Calculate team capacity (velocity × availability)
- Review sprint goal with stakeholders
- Select stories from prioritized backlog
- Fill to 80-85% of capacity (committed)
- Add stretch goals (10-15% additional)
- Identify dependencies and risks
- Break complex stories into tasks
- 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 |
