│  3. Sprint Execution → Daily standups, development          │
│  4. Sprint Review → Demo completed work                     │
│  5. Sprint Retrospective → Identify improvements            │

User Story Format

Standard Template

Copy code
As a [type of user],
I want [some goal]
So that [some reason].

Acceptance Criteria:
- [Criterion 1]
- [Criterion 2]
- [Criterion 3]

Estimate: [Story Points]
Priority: [High/Medium/Low]

Example

Copy code
As a registered user,
I want to reset my password
So that I can regain access if I forget my password.

Acceptance Criteria:
- User can request password reset via email
- Email contains time-limited reset link
- Reset link expires after 1 hour
- User can set new password with validation
- Password must be at least 8 characters

Estimate: 5
Priority: High

Acceptance Criteria Guidelines

INVEST Principle

Good Acceptance Criteria

• Specific: Clear and unambiguous
• Testable: Can be verified
• Realistic: Can be implemented
• Complete: All requirements covered

Prioritization Techniques

MoSCoW Method

Value vs Effort Matrix

Copy code
High Value
    │    ●    ●
    │  ●
    │
    └───────────────► Low Effort

RICE Scoring

Copy code
RICE Score = (Reach × Impact × Confidence) / Effort

Where:
- Reach: Number of people affected
- Impact: Effect on users (1-3)
- Confidence: Estimate certainty (0-100%)
- Effort: Person-months required

Sprint Planning

Pre-Planning Checklist

• Product backlog is groomed
• User stories have acceptance criteria
• Stories are estimated
• Dependencies are identified
• Team capacity is known

Planning Meeting Agenda

1. Sprint Goal (15 min)

   • Define clear, measurable goal
   • Align with product vision

2. Story Selection (30 min)

   • Review high-priority stories
   • Estimate effort
   • Commit to achievable amount

3. Task Breakdown (30 min)

   • Break stories into tasks
   • Assign task owners
   • Identify risks

Backlog Grooming

Regular Session Template

• Frequency: Weekly, 60-90 minutes
• Attendees: Product Owner, Tech Lead, Team
• Agenda:
  1. Review completed items (10 min)
  2. Prioritize new requests (20 min)
  3. Refine upcoming stories (30 min)
  4. Estimate new stories (20 min)
  5. Identify dependencies (10 min)

Story Refinement Checklist

• User story follows template
• Acceptance criteria are clear
• Dependencies identified
• Story is sized appropriately
• Technical approach discussed
• Estimates updated

Velocity Tracking

Velocity Calculation

Copy code
Velocity = Average of completed story points over last 3 sprints

Example:
Sprint 1: 24 points
Sprint 2: 28 points
Sprint 3: 22 points
Velocity: 25 points

Capacity Planning

Copy code
Team Capacity = Velocity × (1 - Buffer)

Where Buffer accounts for:
- Meetings and ceremonies (15%)
- Unplanned work (10%)
- Learning and research (5%)

Common Mistakes

❌ Bad: Vague User Stories

Copy code
As a user,
I want a better interface
So that I can use the app better.

Problems:

• "Better" is not measurable
• No specific features defined
• Cannot verify completion

✅ Good: Specific User Story

Copy code
As a registered user,
I want to filter products by price range
So that I can find products within my budget.

Acceptance Criteria:
- User can set min and max price
- Filter applies to product list
- Price range is optional
- Results update in real-time

❌ Bad: Skipping Acceptance Criteria

Copy code
Story: Implement login feature
Estimate: 3
Priority: High

Problems:

• No clear definition of done
• Team may implement different features
• Testing becomes guesswork

✅ Good: Complete Story

Copy code
Story: Implement login feature

As a registered user,
I want to log in with email and password
So that I can access my account.

Acceptance Criteria:
- User can enter email and password
- Invalid credentials show error message
- Valid credentials redirect to dashboard
- Session persists across page reloads
- Logout clears session

Estimate: 5
Priority: High

Real-World Impact

Before this skill:

• Backlog disorganized
• Unclear priorities
• Sprint planning reactive
• Features miss target

After this skill:

• Backlog groomed and prioritized
• Clear sprint goals
• Predictable delivery
• High-value features first
