Human-in-the-Loop

AI should not always make the final decision.

Some workflows require human expertise.

Example:

AI analyzes insurance claim
        ↓
Risk assessment
        ↓
Human Review
        ↓
Approve / Reject
        ↓
Continue workflow

A workflow can pause:

Step Functions
      ↓
AI analysis
      ↓
Approval required
      ↓
WAIT
      ↓
Human decision
   /       \
Approve   Reject
   ↓        ↓
Continue   Stop

This is useful for:

• financial decisions
• sensitive operations
• compliance
• high-risk actions
• exceptions

API Gateway can expose an endpoint for human feedback.

Human augmentation means AI enhances human capability instead of necessarily replacing human decision-making.
