• Define edge cases and error conditions
• Specify non-functional requirements

Story Splitting

• Split large stories into smaller ones
• Maintain value in each split
• Preserve story relationships
• Track split lineage

Story Estimation

• Estimate story points based on complexity

Usage Patterns

User Story Format

## Standard User Story Format

**As a** [user type/persona],
**I want** [goal/desire],
**So that** [benefit/value].

### Acceptance Criteria
- [ ] Given [context], when [action], then [result]
- [ ] Given [context], when [action], then [result]

### Notes
- [Additional context]
- [Technical considerations]

User Story Generation Example

## Input: Feature Requirement

**Feature**: Advanced Search Filters
**Description**: Users need to filter search results by date, category, and price range.

---

## Generated User Stories

### Story 1: Date Filter
**As a** shopper,
**I want to** filter search results by date range,
**So that** I can find recently added items.

**Acceptance Criteria**:
- [ ] Given I am on search results, when I select a date range, then results show only items added within that range
- [ ] Given I have a date filter applied, when I clear the filter, then all results are shown again
- [ ] Given I select an invalid date range (end before start), when I apply, then I see an error message

**Story Points**: 3
**Priority**: P1

---

### Story 2: Category Filter
**As a** shopper,
**I want to** filter search results by category,
**So that** I can narrow down to relevant items.

**Acceptance Criteria**:
- [ ] Given I am on search results, when I select one or more categories, then only matching items show
- [ ] Given multiple categories selected, when I view results, then items from any selected category appear (OR logic)
- [ ] Given I am on search results, when categories load, then I see a count of items per category

**Story Points**: 5
**Priority**: P1

---

### Story 3: Price Range Filter
**As a** budget-conscious shopper,
**I want to** filter search results by price range,
**So that** I only see items I can afford.

**Acceptance Criteria**:
- [ ] Given I am on search results, when I set min and max price, then only items in that range show
- [ ] Given I set only min price, when I apply filter, then items at or above that price show
- [ ] Given I set only max price, when I apply filter, then items at or below that price show
 [ ] Given I enter non-numeric values, when I try to apply, then I see a validation error

INVEST Validation Template

## INVEST Validation Checklist

### Story: [Story Title]

| Criterion | Pass | Notes |
|-----------|------|-------|
| **Independent** | [ ] | Can be delivered without other stories |
| **Negotiable** | [ ] | Implementation details are flexible |
| **Valuable** | [ ] | Delivers value to user or business |
| **Estimable** | [ ] | Team can estimate with confidence |
| **Small** | [ ] | Can be completed in one sprint |
| **Testable** | [ ] | Has clear acceptance criteria |

### Validation Result
- **Score**: 5/6
- **Issues**: Story too large (not Small)
- **Recommendation**: Split into smaller stories

Story Splitting Patterns

## Story Splitting Techniques

### 1. Split by Workflow Steps
Original: "User can complete checkout"
Split into:
- User can add items to cart
- User can enter shipping address
- User can enter payment info
- User can review and confirm order

### 2. Split by Business Rules
Original: "User can apply discount codes"
Split into:
- User can apply percentage discount
- User can apply fixed amount discount
- User can apply free shipping code

### 3. Split by Data Variations
Original: "User can export report"
Split into:
- User can export report as CSV
- User can export report as PDF
- User can export report as Excel

### 4. Split by Operations (CRUD)
Original: "User can manage their profile"
Split into:
- User can view their profile
- User can edit their profile
- User can upload profile photo
- User can delete their account

### 5. Split by Platform
Original: "User can view dashboard"
Split into:
- User can view dashboard on web
- User can view dashboard on mobile app
- User can view dashboard on tablet

Job Story to User Story Conversion

## Job Story Format
When [situation],
I want to [motivation],
So I can [expected outcome].

## Conversion Example

### Job Story
When I'm preparing for my weekly team meeting,
I want to quickly see project status updates,
So I can discuss blockers and celebrate wins.

### Converted User Stories

**Story 1**: Dashboard Overview
As a team lead,
I want to see a summary of all project statuses on one page,
So that I can quickly prepare for team meetings.

**Story 2**: Recent Activity Feed
As a team lead,
I want to see recent updates and changes to projects,
So that I know what happened since my last check.

**Story 3**: Blocker Highlighting
As a team lead,
I want blocked items to be visually highlighted,
So that I can prioritize discussion of blockers in meetings.

Best Practices

1. Focus on Value: Every story should deliver value to the user
2. Keep Stories Small: If estimate > 8 points, consider splitting
3. Write Testable Criteria: Each criterion should be verifiable
4. Avoid Technical Details: Focus on what, not how
5. Include Context: Provide enough detail for the team
6. Maintain Traceability: Link stories to requirements/research

Common Pitfalls

1. Technical Stories: "Refactor database" - frame as user benefit
2. Too Large: Break down epic-sized stories
3. Too Small: Don't create tasks disguised as stories
4. Missing Acceptance Criteria: Always include testable criteria
5. Vague Value Statement: Be specific about the benefit
