Resolving Conflicts among Business Rules

In real-world of complex decision modeling, business analysts frequently face issues related to diagnostic and resolution of business rule conflicts. To avoid conflicts, business analysts have to add more and more rules making their maintenance a real problem. Today enterprise-level rule repositories achieved such a high level of maturity and internal complexity that absence of automatic conflict resolution tools will lead to unnecessary growth of rules and may potentially convert rule repositories into non-maintainable “monsters”.

At the recent BR conferences this topic was addressed by major open source BR vendors.
