Story Points: 5
Priority: Must Have
Sprint: Sprint 3

CRM Examples

Story 3: Automatic Lead Scoring

Title: Automatic Lead Scoring Based on Behavior

As a sales manager

So that I can check order details without internet connection

Acceptance Criteria:
- Given I have previously viewed orders while online
  When I open the app offline
  Then I can see my cached order history
- Given I am offline
  When I try to view order details
  Then I see the last synced information with "offline" indicator
- Given I regain internet connection
  When the app detects connectivity

ERP Examples

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 for approval
- Given a PO is created for $10K-$50K
  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 Points: 13
Priority: Must Have

CDP Examples

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

Story Points: 21

Acceptance Criteria Formats

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 3

Example:

- [ ] 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 details

Scenario-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)

Definition of Ready (DoR)

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:

Best Practices

Make stories too large (>13 points)
Skip acceptance criteria
Write vague or ambiguous stories
Include implementation details
Create dependencies between stories in same sprint
