What Are Acceptance Criteria?
Acceptance criteria are a set of predefined requirements that must be met for a user story to be considered complete. They define the boundaries of a story and establish a shared understanding between the product owner, development team, and stakeholders about what needs to be delivered.
Core Definition
Acceptance criteria are conditions that a software product must satisfy to be accepted by a user, customer, or other stakeholder. They serve as the "definition of done" for individual user stories.
Think of acceptance criteria as:
- • A checklist that confirms story completion
- • The foundation for test cases
- • A contract between stakeholders and developers
- • Clear boundaries that prevent scope creep
Why Acceptance Criteria Matter
Without clear acceptance criteria, teams operate in ambiguity. Developers make assumptions, testers aren't sure what to validate, and product owners struggle to determine if stories meet business requirements.
✅ With Good Criteria
- • Everyone knows what "done" means
- • Developers build the right features
- • QA can write effective test cases
- • Scope is clearly defined
- • Fewer surprises during review
❌ Without Clear Criteria
- • Constant clarification needed
- • Stories rejected during review
- • Scope creep is common
- • Testing is incomplete
- • Team frustration increases
Acceptance Criteria vs. Other Agile Concepts
It's important to understand how acceptance criteria differ from related agile concepts:
| Concept | Purpose | Scope |
|---|---|---|
| Acceptance Criteria | Define when a story is complete | Individual user story |
| Definition of Done | Team-wide quality standards | All work items |
| User Story | Describe user need and value | Feature from user perspective |
| Test Cases | Validate functionality works | Derived from acceptance criteria |
Key Distinction
The Definition of Done (DoD) is a general checklist that applies to all stories (code reviewed, tested, documented, etc.). Acceptance criteria are specific to each individual story and define its unique functional requirements.
Acceptance Criteria Formats and Templates
There are several proven formats for writing acceptance criteria. Choose the one that best fits your story type and team preferences.
1. Given-When-Then (Scenario Format)
The most popular format, based on Behavior-Driven Development (BDD). It clearly describes the context, action, and expected outcome.
Template Structure:
Given [some context or precondition]
When [an action is performed]
Then [expected result or outcome]
Real Example: Login Functionality
Scenario 1: Successful login
Given a registered user is on the login page
When they enter valid credentials and click "Log In"
Then they are redirected to their dashboard
Scenario 2: Invalid credentials
Given a user is on the login page
When they enter incorrect credentials
Then an error message "Invalid username or password" is displayed
And they remain on the login page
✅ Best for:
- • User interactions and workflows
- • Complex scenarios with multiple conditions
- • Teams practicing BDD
2. Checklist Format (Rules-Based)
A straightforward bullet-point list of conditions that must be met. Simple and easy to verify.
Template Structure:
• [Specific requirement or condition]
• [Another requirement or condition]
• [Edge case or validation rule]
Real Example: Password Reset
• User receives reset email within 2 minutes
• Reset link expires after 24 hours
• New password must be at least 8 characters
• New password cannot match last 3 passwords
• Success message displayed after reset
• User automatically logged in after password change
✅ Best for:
- • Configuration or setup stories
- • Stories with multiple independent requirements
- • Quick validation needs
3. Acceptance Test Format
Focuses on specific test scenarios with clear pass/fail criteria. More detailed than other formats.
Real Example: Search Functionality
Test 1: Basic search
Input: Search for "laptop"
Expected: Display all products containing "laptop" in title or description
Expected: Results sorted by relevance
Test 2: No results
Input: Search for "xyzabc123"
Expected: Display "No results found" message
Expected: Show suggestions or popular items
Test 3: Special characters
Input: Search with special characters "#@%"
Expected: System handles gracefully without errors
✅ Best for:
- • QA-focused teams
- • Stories requiring detailed test coverage
- • Complex validation scenarios
Real-World Examples by Story Type
Learn from practical examples across different types of user stories commonly found in agile development.
E-commerce: Shopping Cart
User Story:
As a customer, I want to add items to my shopping cart so that I can purchase multiple products in a single transaction.
Acceptance Criteria:
Given a customer is viewing a product page
When they click "Add to Cart"
Then the item is added to their cart with selected quantity and options
And cart icon shows updated item count
And a success notification appears
Given the same item already exists in cart
When customer adds it again
Then the quantity is increased rather than creating duplicate entry
• Cart persists across browser sessions for logged-in users
• Out-of-stock items cannot be added to cart
• Cart displays subtotal automatically
SaaS: User Dashboard
User Story:
As a project manager, I want to see a dashboard of team productivity metrics so that I can identify areas for improvement.
Acceptance Criteria:
• Dashboard loads within 3 seconds
• Displays tasks completed (current week vs. previous week)
• Shows average task completion time by team member
• Includes sprint velocity chart for last 6 sprints
• Metrics update in real-time when data changes
• Users can filter by date range (7/30/90 days or custom)
• Export functionality available as PDF or CSV
• Dashboard is responsive on tablet and desktop
Mobile App: Push Notifications
User Story:
As a user, I want to receive push notifications for important updates so that I stay informed without constantly checking the app.
Acceptance Criteria:
Given user has enabled notifications
When a relevant event occurs
Then push notification is sent within 30 seconds
And notification appears even when app is closed
Given user taps on a notification
When app opens
Then user is directed to relevant content
• Users can enable/disable notifications in settings
• Notification preferences persist across devices
• Quiet hours can be configured (no notifications 10pm-7am)
• Works on both iOS and Android platforms
API: Authentication Endpoint
User Story:
As an API consumer, I want to authenticate using JWT tokens so that I can securely access protected endpoints.
Acceptance Criteria:
• POST /auth/login accepts username and password
• Returns JWT token with 24-hour expiration
• Returns 401 status for invalid credentials
• Returns 200 status with token for valid credentials
• Token includes user ID and role in payload
• Rate limiting: maximum 5 attempts per minute per IP
• Response time under 500ms for 95th percentile
• Passwords are never logged or stored in plain text
• API documentation updated with request/response examples
Best Practices for Writing Acceptance Criteria
High-performing agile teams follow proven practices that make their acceptance criteria clear, testable, and valuable. Implement these techniques to elevate your story quality.
The INVEST Criteria Applied
Good acceptance criteria follow the INVEST principles just like user stories:
Independent
Each criterion can be tested separately without dependencies on others
Negotiable
Details can be discussed and refined during sprint planning
Valuable
Each criterion represents meaningful value to users or business
Estimable
Development team can estimate effort required
Small
Criteria are specific enough to be completed in a single sprint
Testable
Pass/fail determination is clear and objective
Essential Best Practices
1. Use Clear, Unambiguous Language
❌ Vague:
"System should be fast"
"Page should look good"
✅ Specific:
"Page loads in under 2 seconds"
"Responsive design works on screens 320px+"
2. Make Criteria Testable and Measurable
Every criterion should have a clear pass/fail outcome. Include specific numbers, timeframes, or observable behaviors.
Good measurable criteria include:
- • Specific numeric values (load time, character limits, file size)
- • Observable actions (displays message, redirects to page, sends email)
- • Concrete states (enabled/disabled, visible/hidden, success/error)
3. Cover Both Happy Path and Edge Cases
Don't just describe the ideal scenario. Include error handling, validation, and boundary conditions.
Happy path: User successfully completes action
Edge cases: Invalid input, network errors, concurrent users, empty states
Boundary conditions: Maximum/minimum values, character limits, timeout thresholds
4. Focus on "What" Not "How"
Describe the desired outcome, not the technical implementation. This gives developers flexibility in their approach.
❌ Implementation-focused:
"Use bcrypt to hash the password"
✅ Outcome-focused:
"Password is securely encrypted in database"
5. Keep Criteria Independent
Each criterion should be verifiable on its own without requiring other criteria to be completed first.
6. Involve the Whole Team
Acceptance criteria should be collaborative effort between product owner, developers, and QA during refinement sessions.
Team Input Benefits:
- • Developers identify technical constraints early
- • QA suggests additional test scenarios
- • Product owner ensures business value alignment
- • UX designer validates user experience requirements
Common Mistakes to Avoid
• Too many criteria: If a story has more than 10 criteria, it's likely too big and should be split
• Implementation details: Don't specify technical solutions unless absolutely necessary
• Vague language: Avoid words like "good," "fast," "user-friendly" without defining them
• Missing negative cases: Always include what should NOT happen
• Writing too late: Criteria should be defined before development starts
Advanced Techniques for Complex Stories
Some user stories require more sophisticated approaches to acceptance criteria. Here are advanced techniques used by experienced teams.
1. Example Mapping for Complex Scenarios
When stories have multiple rules and examples, use example mapping workshops to explore scenarios before writing criteria.
Process:
- Write the story on a yellow card
- Identify rules on blue cards
- Create examples on green cards for each rule
- Note questions or uncertainties on red cards
- Convert validated examples into acceptance criteria
2. Acceptance Criteria for Non-Functional Requirements
Performance, security, and scalability requirements need special consideration.
Example: Performance Optimization Story
• Dashboard loads in under 2 seconds for 95th percentile of requests
• System handles 1000 concurrent users without degradation
• Database queries complete in under 500ms
• Page size under 2MB including all assets
• Performance metrics tracked in monitoring dashboard
3. Acceptance Criteria for Spikes and Research
Technical spikes and research stories need different criteria focused on outcomes rather than features.
Example: Technical Spike
• Document comparing 3 authentication libraries (Auth0, Firebase, custom JWT)
• Performance benchmarks for each option with 10k+ users
• Cost analysis including licensing and infrastructure
• Proof of concept demonstrating feasibility
• Recommendation with reasoning shared with team
• Time-boxed to 2 days maximum
4. Using Acceptance Criteria Hierarchies
For epic-level stories, create hierarchical criteria with must-haves, should-haves, and nice-to-haves.
Must Have (MVP)
Core functionality required for story completion
Should Have
Important but can be deferred if needed
Nice to Have
Enhancements that add polish
