A method for identifying conflicting and duplicate rules in a decision support system is provided. The method includes establishing a first subsystem including a protocol of existing rules, each existing rule includes an input feature. The method also includes creating a new rule that includes an input feature, and comparing terminology in the input feature of the new rule against terminology in the input feature of each existing rule of the protocol using a second subsystem and determining whether the new rule and at least one existing rule from the protocol are similar.
