Definition
Why rules engines scale
Rules engines define policies as independent rules rather than duplicating logic across branching trees. This reduces maintenance burden and inconsistency risk when policies change frequently.
Common features
- Versioning and effective dating
- Audit trails for rule changes and outcomes
- Real-time execution as data changes
- Override controls with reasons and authorities
