Card          — Brief description on index card
              → Captures essence, not details
              → Placeholder for conversation

Conversation  — Discussion between team members
              → Explore edge cases
              → Clarify assumptions
              → Uncover hidden requirements

Confirmation  — Acceptance criteria
              → Defines "done"
              → Testable conditions
              → Given-When-Then format

Independent   — Story stands alone, minimal dependencies
Negotiable    — Details emerge through conversation
Valuable      — Delivers value to users or business
Estimable     — Team can estimate effort
Small         — Completable within one sprint
Testable      — Clear acceptance criteria

## Good User Stories

### Feature: Password Reset
As a user who forgot my password,
I want to reset it via email,
So that I can regain access to my account without contacting support.

**Acceptance Criteria:**
- Given I'm on the login page
- When I click "Forgot Password"
- Then I see a form requesting my email address

- Given I've entered my registered email
- When I submit the form
- Then I receive a password reset link within 2 minutes

- Given I click the reset link within 24 hours
- When I set a new password (min 8 chars, 1 number, 1 symbol)
- Then I'm logged in automatically

### Feature: Bulk Upload
As a content manager,
I want to upload multiple products via CSV,
So that I can save time compared to manual entry.

**Acceptance Criteria:**
- Given I'm on the products page
- When I click "Bulk Upload" and select a CSV file
- Then the system validates the file format (max 10MB, .csv only)

- Given the CSV has 1000 rows
- When I start the upload
- Then I see a progress bar showing completion percentage

- Given the upload completes
- When I view the results
- Then I see: success count, error count, downloadable error report

❌ Too technical
"As a user, I want the API to return a 200 status code"
→ Focus on user benefit, not implementation

❌ Too vague
"As a user, I want the system to be fast"
→ Define measurable performance targets

❌ Missing the "so that"
"As a user, I want to filter products by price"
→ Add the value: "so that I can find items within my budget"

❌ Too large (Epic)
"As a user, I want a complete e-commerce checkout experience"
→ Break into smaller stories: cart, address, payment, confirmation

Given [precondition/context]
When [action/trigger]
Then [expected outcome]

And [additional context/outcome]

✓ Keep scenarios focused (one behavior per scenario)
✓ Maintain clear separation of Given/When/Then
✓ Avoid UI-specific details (test behavior, not implementation)
✓ Make criteria testable and measurable
✓ Include both happy path and edge cases
✓ Use real user interactions, not hypothetical

## E-commerce Checkout

Scenario: Successful payment with saved card
  Given I have items in my cart
  And I'm logged in with a saved payment method
  When I click "Place Order"
  Then I see an order confirmation page
  And I receive a confirmation email within 2 minutes
  And my cart is emptied

Scenario: Payment declined
  Given I'm at the payment step
  When I submit payment and the card is declined
  Then I see an error message: "Payment declined. Please try another card."
  And I remain on the payment page
  And my cart items are preserved

Scenario: Session timeout during checkout
  Given I've been idle for 30 minutes
  When I attempt to place an order
  Then I'm redirected to login
  And my cart items are preserved after re-authentication

## Search Feature

Scenario: Search with results
  Given I'm on the homepage
  When I search for "laptop"
  Then I see results within 500ms
  And results are ranked by relevance
  And I see result count: "Showing 1-20 of 156 results"

Scenario: Search with no results
  Given I'm on the search page
  When I search for "xyznonexistent"
  Then I see "No results found for 'xyznonexistent'"
  And I see search suggestions or alternative queries

For simpler features, use a checklist:

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

Reach      — How many users affected per time period?
             (users/quarter, transactions/month)
Impact     — How much does it improve their experience?
             3 = Massive, 2 = High, 1 = Medium, 0.5 = Low, 0.25 = Minimal
Confidence — How certain are we?
             100% = High data, 80% = Medium, 50% = Low
Effort     — Person-months required
             (engineering + design + PM time)

ICE Score = (Impact + Confidence + Ease) / 3

Impact     — 1-10: How much business/user value?
Confidence — 1-10: How certain are we?
Ease       — 1-10: How easy to implement? (10 = very easy)

Must Have      — Critical for launch, non-negotiable
                 Without this, the product fails

Should Have    — Important but not vital
                 Painful to omit, but workarounds exist

Could Have     — Nice to have, "vitamins not painkillers"
                 Include if time/resources allow

Won't Have     — Explicitly out of scope
                 Defer to future releases

Basic Needs       — Must-haves, assumed by users
                    Absence = dissatisfaction, presence = neutral
                    Example: Website loads, checkout works

Performance       — More is better, linear satisfaction
                    Example: Faster page load, more payment options

Delighters        — Unexpected features that wow
                    Absence = neutral, presence = delight
                    Example: Free shipping, personalized recommendations

Indifferent       — Users don't care either way
                    Example: Animated logo, theme customization

Best practice: Combine frameworks

1. Use MoSCoW to define release scope
   → Separate must-haves from nice-to-haves

2. Use RICE to rank must-haves
   → Sequence within release based on impact

3. Use Kano to ensure balance
   → Don't over-invest in basics, under-invest in delight

Example:
- All "Must Have" items → Score with RICE → Build in RICE order
- Validate with Kano → Ensure we have delighters, not just basics
