Flpbalada User Story Fundamentals

User Story Fundamentals - Capturing User-Centered Requirements

A structured framework for capturing product requirements from the user's perspective. User stories help teams understand who needs a feature, what they want to accomplish, and why it matters.

When to Use This Skill

• Writing backlog items
• Defining feature requirements
• Prioritizing development work
• Communicating with development teams
• Breaking down epics into actionable work
• Ensuring user focus in product decisions

User Story Format

THE STANDARD TEMPLATE

"As a [type of user],
 I want [some goal],
 so that [some reason/benefit]."

Components:
┌─────────────────────────────────────────────────────┐
│  WHO: The user persona or role                      │
│  WHAT: The desired functionality or goal            │
│  WHY: The business value or user benefit            │
└─────────────────────────────────────────────────────┘

This format shifts focus from WRITING about requirements
to TALKING about them, with users at the center.

Core Components

WHO - User Persona

Specificity Spectrum:

Generic (avoid):
├── "As a user..."
└── "As a customer..."

Better:
├── "As a first-time visitor..."
├── "As a returning customer..."
├── "As an admin user..."
└── "As a mobile user..."

Best (with job context):
├── "As a marketing manager who needs weekly reports..."
├── "As a parent shopping for school supplies..."
├── "As a developer debugging production issues..."
└── "As a sales rep preparing for a client meeting..."

WHAT - Desired Functionality

Focus on GOALS, not IMPLEMENTATION:

❌ "I want a blue button in the header"
   (prescriptive, limits solutions)

✓ "I want to quickly access my saved items"
   (goal-focused, enables creativity)

❌ "I want a REST API endpoint"
   (technical implementation)

✓ "I want to integrate my data with external tools"
   (user goal, flexible implementation)

WHY - Business Value

The "So That" Connection:

This part explains:
├── What pain it solves
├── What value it creates
├── Why this matters to the user
└── How it connects to business goals

Without "so that":
"As a user, I want to filter search results"
→ Why? What's the actual need?

With "so that":
"As a user, I want to filter search results
 so that I can find relevant items faster
 when browsing large catalogs"
→ Clear value, enables better solutions

INVEST Criteria

QUALITY CHECKLIST FOR USER STORIES

I - Independent
│   Can be developed and delivered separately
│   No tight coupling to other stories
│
N - Negotiable
│   Details open to discussion
│   Not a rigid contract
│
V - Valuable
│   Delivers real value to user or business
│   Not just technical tasks
│
E - Estimable
│   Team can estimate effort
│   Clear enough to size
│
S - Small
│   Fits within single sprint
│   If too big, split it
│
T - Testable
│   Has clear acceptance criteria
│   Can verify when complete

Acceptance Criteria

Definition

ACCEPTANCE CRITERIA (AC)

Purpose: Define what makes the story "done"
Format: Specific, testable conditions

Example Story:
"As a user, I want to reset my password via email
 so that I can regain access if I forget it"

Acceptance Criteria:
□ User can request reset from login page
□ Email sent within 60 seconds of request
□ Reset link expires after 24 hours
□ Link works only once
□ Password must meet security requirements
□ User receives confirmation after successful reset

Writing Good AC

Prioritization Framework

RICE Scoring

RICE = (Reach × Impact × Confidence) / Effort

Reach: How many users affected per time period?
       (100 users/month, 1000 users/quarter)

Impact: How much will it move the needle?
        3 = Massive, 2 = High, 1 = Medium, 0.5 = Low, 0.25 = Minimal

Confidence: How sure are we about estimates?
            100% = High, 80% = Medium, 50% = Low

Effort: Person-months of work
        (0.5, 1, 2, 3...)

Higher RICE score = Higher priority

MoSCoW Method

CATEGORIZATION FOR RELEASE PLANNING

MUST Have (Non-negotiable)
├── Critical for release
├── Legal/compliance requirements
└── Core value proposition

SHOULD Have (Important)
├── High value but not critical
├── Workarounds exist
└── Strong user demand

COULD Have (Nice to have)
├── Desired but not necessary
├── Easy wins if time permits
└── Lower user impact

WON'T Have (Not this time)
├── Explicitly out of scope
├── Future consideration
└── Documented for later

Story Splitting Techniques

When to Split

SPLIT IF:
├── Can't complete in one sprint
├── Story points > 13 (or team max)
├── Multiple distinct user values
├── Contains "and" connecting features
└── Too many acceptance criteria

Splitting Methods

1. BY WORKFLOW STEPS
   Original: "User can complete purchase"
   Split:
   ├── User can add items to cart
   ├── User can enter shipping info
   ├── User can enter payment info
   └── User can confirm and place order

2. BY USER TYPE
   Original: "User can view dashboard"
   Split:
   ├── Admin can view full dashboard
   ├── Manager can view team metrics
   └── User can view personal stats

3. BY OPERATIONS (CRUD)
   Original: "User can manage contacts"
   Split:
   ├── User can create contact
   ├── User can view contact details
   ├── User can edit contact
   └── User can delete contact

4. BY DATA VARIATIONS
   Original: "User can import data"
   Split:
   ├── User can import CSV files
   ├── User can import Excel files
   └── User can import from API

5. BY ACCEPTANCE CRITERIA
   Original: "User can search products"
   Split:
   ├── User can basic keyword search
   ├── User can filter by category
   ├── User can sort results
   └── User can save search

Definition of Done vs. Acceptance Criteria

DEFINITION OF DONE (DoD)        ACCEPTANCE CRITERIA (AC)
────────────────────────        ────────────────────────
Universal checklist             Story-specific conditions
Same for all stories            Unique per story
Quality standard                Functional requirements

DoD Examples:                   AC Examples:
□ Code reviewed                 □ User can X
□ Tests written                 □ System does Y
□ Documentation updated         □ Data validates as Z
□ No critical bugs              □ Performance meets N

Common Mistakes

ANTI-PATTERNS TO AVOID

❌ Implementation as story
   "Create database table for users"
   → Not user value, technical task

❌ Missing "so that"
   "As a user, I want to search"
   → Why? What problem does this solve?

❌ Too vague
   "As a user, I want a better experience"
   → What specifically? Not actionable

❌ Too large
   "As a user, I want full account management"
   → Multiple features, needs splitting

❌ Solution prescribed
   "As a user, I want a dropdown menu"
   → Describes UI, not user goal
