Story 5: Multi-level Purchase Approval
Title: Multi-level Purchase Order Approval Workflow
As a procurement manager
I want purchase orders to route through appropriate approval levels
So that spending is controlled according to company policy
Acceptance Criteria:
- Given a PO is created for $1K-$10K
When the PO is submitted

Then it routes to department manager, then finance director
- Given a PO is created for >$50K
When the PO is submitted
Then it routes to department manager, finance director, then CFO
- Given an approver is out of office
When a PO requires their approval
Then it automatically routes to their designated backup
- Given an approver rejects a PO
When the rejection is submitted
Then the requester is notified with rejection reason
Approval Matrix:
- $0-$1K: Auto-approved
- $1K-$10K: Department Manager
- $10K-$50K: Department Manager → Finance Director
- >$50K: Department Manager → Finance Director → CFO

Story 6: Customer Identity Resolution
Title: Unify Customer Profiles Across Channels
As a marketing analyst
I want customer data from web, mobile, and CRM to be unified
So that I have a complete view of each customer
Acceptance Criteria:
- Given a customer logs in on web and mobile with same email
When identity resolution runs
Then both profiles are merged into single customer record
- Given a customer has multiple emails
When I manually link the profiles
Then all activities are consolidated under primary profile
- Given profiles are merged
When I view the customer record
Then I see all touchpoints across channels in timeline
- Given a merge conflict occurs (different names, addresses)
When the system detects conflict
Then it flags for manual review
Matching Rules:
- Email (exact match) - High confidence
- Phone + Name (fuzzy match) - Medium confidence
- Cookie ID + Email domain - Low confidence

Given-When-Then (Gherkin)
Given [context/precondition]
When [action/event]
Then [expected outcome]Example:
Given I am a logged-in customer
When I click "View Orders"
Then I see a list of my orders sorted by date (newest first)Checklist Format
- [ ] Criterion 1
- [ ] Criterion 2
- [ ] Criterion 3Example:
- [ ] Order list displays order number, date, total, status
- [ ] Orders are paginated (20 per page)
- [ ] User can filter by status (All, Processing, Shipped, Delivered)
- [ ] User can search by order number
- [ ] Clicking an order opens order detailsScenario-Based
Scenario 1: [Happy path]
Scenario 2: [Alternative path]
Scenario 3: [Error case]Story Splitting Techniques
When a story is too large (>13 points), split by:
1. Workflow Steps
- Original: "User can complete checkout"
- Split: "Enter shipping info", "Select shipping method", "Enter payment", "Review order"
2. Business Rules
- Original: "Calculate shipping costs"
- Split: "Standard shipping", "Express shipping", "International shipping"
3. CRUD Operations
- Original: "Manage products"
- Split: "Create product", "Update product", "Delete product", "View products"
4. Data Variations
- Original: "Import customer data"
- Split: "Import from CSV", "Import from Excel", "Import from API"
5. Platforms
- Original: "Mobile app checkout"
- Split: "iOS checkout", "Android checkout"
6. Simple/Complex
- Original: "Search products"
- Split: "Basic keyword search", "Advanced filters", "Faceted search"
Story Estimation
Story Points (Fibonacci: 1, 2, 3, 5, 8, 13, 21)
- 1 point: Trivial change (few hours)
- 2 points: Simple feature (half day)
- 3 points: Straightforward feature (1 day)
- 5 points: Moderate complexity (2-3 days)
- 8 points: Complex feature (3-5 days)
- 13 points: Very complex (5-8 days) - consider splitting
- 21+ points: Too large - must split
T-Shirt Sizing (Alternative)
- XS: 1-2 points
- S: 3-5 points
- M: 8 points
- L: 13 points
- XL: 21+ points (split required)

Story is ready for sprint when:
- User story follows INVEST criteria
- Acceptance criteria are clear and testable
- Dependencies identified and resolved
- Wireframes/mockups available (if UI work)
- Business rules documented
- Story estimated by team
- Priority assigned
- Technical approach discussed
Definition of Done (DoD)
Story is complete when:
- Code complete and peer reviewed
- Unit tests written (>80% coverage)
- Integration tests passing
- All acceptance criteria met
- Manual testing completed
- Documentation updated
- Deployed to staging environment
- Product owner approved
Best Practices
✅ Do:
- Write from user perspective
- Focus on value, not implementation
- Keep stories small and focused
- Include clear acceptance criteria
- Involve the team in writing stories
- Refine stories before sprint planning
- Link stories to epics and features
❌ Don't:
- Write technical tasks as user stories
- Make stories too large (>13 points)
- Skip acceptance criteria
- Write vague or ambiguous stories
- Include implementation details
- Create dependencies between stories in same sprint

Next Steps
After writing user stories:
- Refine with team during backlog grooming
- Create acceptance criteria (see
acceptance-criteriaskill) - Estimate during planning poker
