What is a definitional rule?

Definitional rules are a type of business rule that form theories or produce information. They

represent something that is fundamentally true or untrue about some concept within the

organization. Unlike behavioral rules, which are about people’s behavior, definitional rules constitute

operational knowledge of the organization. They cannot be violated but can be misused. For

instance, a definitional rule might be used to classify different categories of customers based on

contractual agreements or order quantities.
