# Integration with Onboarding Engine

Reviews logic is defined in [Playbooks](/articles/guides/playbooks-playbook-rules) in Action nodes. The system handles the entire routing process:

1. **Identifies the review kind** based on your Playbook configuration
2. **Selects the appropriate queue** for that review type
3. **Calculates the due date** using the review kind's SLA settings
4. **Assigns the base priority** from the review kind definition
5. **Begins dynamic prioritization** as the review ages toward its deadline

This automation ensures consistent routing and prioritization without manual intervention.
