## Getting Started

### 1. Setup the Review System

Initialize the review system with sample data:

```bash
# Setup sample workflows and reviewer profiles
npm run setup-review-system

# Validate the setup
npm run setup-review-system -- --validate
```

### 2. Create Reviewer Profiles

```typescript
// Create a new reviewer profile
const reviewerData = {
  userId: 'user123',
  name: 'John Smith',
  email: 'john.smith@company.com',
  title: 'Senior Business Analyst',
  department: 'Business Analysis',
  organization: 'ADPA Enterprise',

    workingDays: [1, 2, 3, 4, 5],
    maxConcurrentReviews: 4
  }
};

// API call to create reviewer
const response = await fetch('/api/v1/reviewers', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },

## Workflow Examples

### Example 1: Standard Document Review Process

1. **Document Generation**: System generates project charter
2. **Automatic Review Creation**: Review request created with priority "high"
3. **Reviewer Assignment**: System assigns project manager and compliance officer
4. **Review Process**: 
   - Stage 1: Project manager reviews for completeness (3 days)
   - Stage 2: Compliance officer reviews for PMBOK compliance (5 days)
5. **Feedback Collection**: Reviewers provide structured feedback
6. **Decision**: Document approved or revision requested
7. **Completion**: Document marked as approved and stakeholders notified

### Example 2: Technical Document Review with Parallel Stages

1. **Document Generation**: System generates technical architecture document
2. **Review Creation**: Technical review workflow triggered
3. **Parallel Assignment**: Technical reviewer and subject matter expert assigned simultaneously
4. **Concurrent Review**: Both reviewers work in parallel
5. **Consolidation**: System consolidates feedback from both reviewers
6. **Final Decision**: Document approved if both reviewers approve

### Example 3: Feedback-Driven Regeneration

1. **Initial Review**: Document receives feedback requesting major revisions
2. **Regeneration Request**: System triggers document regeneration with feedback context
3. **Enhanced Generation**: AI incorporates feedback into new document version
4. **New Review**: Fresh review created for regenerated document
5. **Approval**: Improved document meets quality standards and gets approved

## Review Criteria and Quality Gates

### Document Quality Assessment

The system evaluates documents based on:

- **Content Accuracy** (25%): Factual correctness and relevance
- **Technical Compliance** (20%): Adherence to technical standards
- **Completeness** (20%): All required sections and information present
- **Clarity** (15%): Clear and understandable language
- **Formatting** (10%): Proper structure and presentation
- **Stakeholder Alignment** (10%): Meets stakeholder expectations

### Quality Thresholds

- **Minimum Passing Score**: 70/100
- **Good Quality**: 80/100
- **Excellent Quality**: 90/100

### Escalation Triggers

- **Overdue Reviews**: 24 hours past due date
- **Quality Issues**: Score below threshold
- **No Response**: 48 hours without reviewer action
- **Multiple Rejections**: 3+ revision requests

## Performance Metrics

### Reviewer Metrics

- **Average Review Time**: Time from assignment to completion
- **Quality Score**: Average quality of feedback provided
- **On-Time Completion Rate**: Percentage of reviews completed by due date
