# Step 6.2: Create Design Delivery

## Your Task

Package your complete testable flow into a Design Delivery YAML file.

---

## Before You Start

**Ensure you have:**

- ✅ Completed step 6.1 (flow is complete)
- ✅ All scenario specifications ready
- ✅ All component definitions ready
- ✅ Clear understanding of user value

---

## Create Design Delivery File

### Step 1: Choose Delivery ID

**Format:** `DD-XXX-name.yaml`

**Examples:**

- `DD-001-login-onboarding.yaml`
- `DD-002-morning-dog-care.yaml`
- `DD-003-calendar-view.yaml`

**Numbering:**

- Start at DD-001 for first delivery
- Increment for each new delivery
- Use leading zeros (DD-001, not DD-1)

---

### Step 2: Copy Template

**Template location:** `templates/design-delivery.template.yaml`

**Create file:** `deliveries/DD-XXX-name.yaml`

```bash
# Create deliveries directory if it doesn't exist
mkdir -p deliveries

# Copy template
cp templates/design-delivery.template.yaml deliveries/DD-001-login-onboarding.yaml
```

---

### Step 3: Fill Out Delivery Metadata

```yaml
delivery:
  id: 'DD-001'
  name: 'Login & Onboarding Flow'
  status: 'ready' # ready | in_development | in_testing | complete
  priority: 'high' # critical | high | medium | low
  version: '1.0'
  created_at: '2024-12-09T12:00:00Z'
  updated_at: '2024-12-09T12:00:00Z'
```

---

### Step 4: Define User Value

**What problem does this solve? What value does it deliver?**

```yaml
user_value:
  problem: |
    Users need to access the app securely and set up their
    family structure before using core features.

  solution: |
    Streamlined onboarding flow that guides users through
    account creation, family setup, and initial dog addition.

  success_criteria:
    - 'User completes signup in under 2 minutes'
    - '90% onboarding completion rate'
    - 'User satisfaction score > 4.5/5'
    - 'Zero critical errors during onboarding'
```

---

### Step 5: List Design Artifacts

**Reference all scenarios and components for this flow:**

```yaml
design_artifacts:
  scenarios:
    - id: '01-welcome'
      path: 'C-Scenarios/01-welcome-screen/'
      description: 'Initial welcome screen with value proposition'

    - id: '02-login'
      path: 'C-Scenarios/02-login/'
      description: 'Login flow for returning users'

    - id: '03-signup'
      path: 'C-Scenarios/03-signup/'
      description: 'Account creation for new users'

    - id: '04-family-setup'
      path: 'C-Scenarios/04-family-setup/'
      description: 'Family/household configuration'

  user_flows:
    - name: 'New User Onboarding'
      path: 'C-Scenarios/flows/new-user-onboarding.md'
      entry_point: '01-welcome'
      exit_point: '04-family-setup'

  design_system_components:
    - component: 'Button'
      variants: ['Primary', 'Secondary', 'Text']
      path: 'D-Design-System/03-Atomic-Components/Buttons/'

    - component: 'Input'
      variants: ['Text', 'Email', 'Password']
      path: 'D-Design-System/03-Atomic-Components/Inputs/'

    - component: 'Card'
      variants: ['Default', 'Elevated']
      path: 'D-Design-System/03-Atomic-Components/Cards/'
```

---

### Step 6: Define Technical Requirements

```yaml
technical_requirements:
  platform:
    frontend: 'React Native 0.72'
    backend: 'Supabase 2.x'
    database: 'PostgreSQL 15'

  integrations:
    - name: 'Supabase Auth'
      type: 'required'
      provider: 'Supabase'
      purpose: 'User authentication and session management'

    - name: 'Email Verification'
      type: 'required'
      provider: 'Supabase'
      purpose: 'Verify user email addresses'

  data_models:
    - model: 'User'
      fields: ['id', 'email', 'name', 'created_at']
      path: 'A-Project-Brief/data-models.md#user'

    - model: 'Family'
      fields: ['id', 'name', 'owner_id', 'created_at']
      path: 'A-Project-Brief/data-models.md#family'

  performance:
    - 'Screen load time < 1 second'
    - 'Form submission response < 500ms'
    - 'Smooth 60fps animations'

  security:
    - 'Password must be hashed (bcrypt)'
    - 'Email verification required'
    - 'Session tokens expire after 30 days'
```

---

### Step 7: Define Acceptance Criteria

```yaml
acceptance_criteria:
  functional:
    - 'User can create account with email and password'
    - 'User receives verification email'
    - 'User can log in with verified credentials'
    - 'User can set up family/household'
    - 'User can skip dog addition during onboarding'

  non_functional:
    - 'All screens load in under 1 second'
    - 'Forms validate input in real-time'
    - 'Error messages are clear and actionable'
    - 'Design system components used correctly'
    - 'Accessibility: WCAG 2.1 AA compliance'

  edge_cases:
    - 'Handle email already exists error'
    - 'Handle network timeout during signup'
    - 'Handle app close mid-onboarding (resume state)'
    - 'Handle invalid email format'
    - 'Handle weak password'
```

---

### Step 8: Add Testing Guidance

```yaml
testing_guidance:
  user_testing:
    - 'Recruit 5-10 new users who have never used the app'
    - 'Observe onboarding completion without assistance'
    - 'Measure time to complete onboarding'
    - "Ask: 'Was anything confusing?'"
    - 'Target: 90% completion rate, < 2 minutes'

  qa_testing:
    - 'Test all happy paths'
    - 'Test all error states'
    - 'Test all edge cases'
    - 'Test on iOS and Android'
    - 'Test with slow network'
    - 'Test with no network'

  design_validation:
    - 'Verify design system compliance'
    - 'Verify accessibility'
    - 'Verify animations and transitions'
    - 'Verify copy matches specifications'
```

---

### Step 9: Estimate Complexity

```yaml
estimated_complexity:
  size: 'medium' # small | medium | large | xlarge
  effort: '2-3 weeks'
  risk: 'low' # low | medium | high

  dependencies:
    - 'Supabase project setup'
    - 'Email service configuration'

  assumptions:
    - 'Supabase Auth SDK is stable'
    - 'Design system components are reusable'
    - 'No major technical blockers'
```

---

## Validation

**Before proceeding, verify:**

- [ ] Delivery ID is unique and follows format
- [ ] All required fields are filled
- [ ] All scenarios are referenced
- [ ] All components are listed
- [ ] Technical requirements are clear
- [ ] Acceptance criteria are testable
- [ ] Complexity estimate is realistic

```
[C] Continue to step-6.3-create-test-scenario.md
```

---

## Success Metrics

✅ Design Delivery file created
✅ All required fields filled
✅ All scenarios and components referenced
✅ Technical requirements documented
✅ Acceptance criteria defined
✅ Testing guidance provided
✅ Complexity estimated

---

## Failure Modes

❌ Missing required fields
❌ Incomplete scenario references
❌ Vague acceptance criteria
❌ Unrealistic complexity estimate
❌ Missing technical requirements

**Remember:** This Design Delivery is the contract between design and development. Be thorough!
