A business rules management system (BRMS) centralizes business rules so organizations can author, manage, test, govern, and automate complex decisions separately from application code. It evolved from expert systems, which assess data through if-then rules created by domain experts. section 2.2 section 2.6
A BRMS commonly combines:
- A rule repository for defining, organizing, and storing business rules. section 2.2
- A rule-authoring environment for creating, modifying, and testing rules through interfaces usable by business users or analysts. section 2.2
- A rule coherence module for assessing new or changed rules and preventing contradictions. section 2.2
Loan eligibility
A financial institution can automate loan decisions with a rule such as: if an applicant exceeds a credit-score threshold and has stable income, approve the application automatically. Similar rule-based decisions support tax preparation, hospital admissions, and vehicle responses to traffic conditions. section 2.2
BRMSs help organizations streamline decision-making by keeping complex rules centralized and manageable. Their decisions depend on the quality, consistency, and suitability of the rules supplied by domain experts. section 2.2 section 2.6
