    ]
  }
}
```

### Get Dashboard Data

```http
GET /api/v1/projects/{projectId}/scope-control/dashboard
```

## Scope Creep Detection Algorithms

### Multi-Algorithm Approach

The system uses multiple detection algorithms to identify scope creep:

1. **Change Velocity Analysis**: Monitors the rate of scope changes over time
2. **Impact Accumulation**: Tracks cumulative impact of changes
3. **Compliance Decline**: Detects decreasing PMBOK compliance scores
4. **Pattern Analysis**: Identifies concerning patterns in change requests
5. **Risk Escalation**: Monitors increasing risk levels

### Adaptive Thresholds

Thresholds are dynamically adjusted based on:
- Project size and complexity
- Historical change patterns
- Team experience level
- Project phase
- Stakeholder engagement level

## PMBOK Compliance Validation

### Validation Criteria

The system validates scope changes against PMBOK 7th Edition standards:

#### Section 5.6 - Control Scope Process

- **Inputs Validation**:
  - Project Management Plan
  - Project Documents
  - Work Performance Data

- **Tools & Techniques**:
  - Variance Analysis
  - Trend Analysis
  - Performance Reviews

- **Outputs Validation**:
  - Work Performance Information
  - Change Requests
  - Project Management Plan Updates

#### Cross-Knowledge Area Integration

- **Stakeholder Engagement** (Section 13)
- **Risk Management** (Section 11)
- **Quality Management** (Section 8)
- **Schedule Management** (Section 6)
- **Cost Management** (Section 7)
- **Resource Management** (Section 9)

### Compliance Scoring

```typescript
interface ComplianceScore {
  basicCompliance: boolean;      // Required fields and impact analysis
  pmbokScore: number;           // PMBOK process compliance (0-1)
  advancedScore: number;        // Cross-knowledge area integration (0-1)
  overallCompliance: boolean;   // Combined compliance result
}
```

## Usage Examples

### Basic Implementation

```typescript
import { AdaptiveScopeControlService } from './services/AdaptiveScopeControlService.js';

const scopeControl = new AdaptiveScopeControlService();

// Initialize monitoring for a project
await scopeControl.initializeProjectMonitoring(project, {
  autoApprovalThreshold: 0.2,
  scopeCreepThreshold: 0.3,
  monitoringFrequency: 60
});

// Submit a scope change
const scopeChange = await scopeControl.submitScopeChange({
  projectId: 'project-123',
  changeType: 'addition',
  description: 'Add new feature',
  requestedBy: 'Product Manager',
  impact: { /* impact details */ }
});

// Check for scope creep
const creepDetected = await scopeControl.detectScopeCreep('project-123');
```

### Event-Driven Integration

```typescript
scopeControl.on('scope_creep_detected', ({ projectId, change, alert }) => {
  console.log(`Scope creep detected in project ${projectId}`);
  // Send notifications, trigger workflows, etc.
});

scopeControl.on('scope_change_approved', ({ change, implementationPlan }) => {
  console.log(`Scope change ${change.id} approved`);
  // Update project documentation, notify stakeholders
});
```

## Configuration

### Default Settings

```typescript
const defaultSettings: AdaptiveControlSettings = {
  autoApprovalThreshold: 0.2,      // 20% impact threshold for auto-approval
  escalationThreshold: 0.5,        // 50% impact threshold for escalation
  scopeCreepThreshold: 0.3,        // 30% creep index threshold
  monitoringFrequency: 60,         // Monitor every 60 minutes
  stakeholderNotificationEnabled: true,
  pmbokValidationEnabled: true,
  predictiveAnalyticsEnabled: true
};
```

### Project-Specific Customization

Settings can be customized per project based on:
- Project complexity
- Team experience
- Stakeholder requirements
- Organizational policies
- Risk tolerance

## Monitoring and Alerts

### Alert Types

1. **Scope Creep Alerts**: Potential scope creep detection
2. **Threshold Breach**: Control thresholds exceeded
3. **Compliance Violations**: PMBOK compliance issues
4. **Risk Escalation**: Increasing risk levels

### Alert Severity Levels

- **Info**: Informational updates
- **Warning**: Attention required
- **Critical**: Immediate action needed

### Recommended Actions

Each alert includes specific recommended actions:
- Process improvements
- Stakeholder engagement
- Documentation updates
- Risk mitigation strategies

- Executives: Dashboard and summary reports

## Troubleshooting

### Common Issues

1. **High False Positive Rate**: Adjust scope creep thresholds
2. **Performance Issues**: Optimize monitoring frequency
3. **Compliance Failures**: Review PMBOK validation criteria
