A method and system for externalization of rules for assessing bodily injury general damages. An insurance company may use an expert system to develop a knowledge base in the form of business rules to process insurance claims. The business rules may be executed to assist an insurance claims adjuster in assessing bodily injury general damages. The task of creation and maintenance of the business rules, used in the assessment of claims, may be automated by the externalization of rules. The user may create a rules data table, which includes data necessary to transform it to business rules, based on a rule syntax structure specified in the template table. The transformation method orchestrates the combining of the data from the rules data table and the rule syntax structure specified in the template table and line text table. The new business rule may be saved as text in an insurance database. Changing the data stored in the rules data table and using the transformation method may accomplish updating and/or customizing the business rules.
