    • A Business rule is a statement that defines or constrains some spect of the business and always resolves to either true or false. Business rules are intended to assert business structure or to control or influence the behavior of the business.[1] Business rules describe the operations, definitions and constraints that apply to an organization. Business rules can apply to people, processes, corporate behavior and computing systems in an organization, and are put in place to help the organization achieve its goals.

      For example a business rule might state that no credit check is to be performed on return customers. Other examples of business rules include requiring a rental agent to disallow a rental tenant if their credit rating is too low, or requiring company agents to use a list of preferred suppliers and supply schedules.

      While a business rule may be informal or even unwritten, writing the rules down clearly and making sure that they don't conflict is a valuable activity. When carefully managed, rules can be used to help the organization to better achieve goals, remove obstacles to market growth, reduce costly mistakes, improve communication, comply with legal requirements, and increase customer loyalty.

    • A rule’s being “under business jurisdiction” means that it is under the jurisdiction of the semantic community that it governs or guides - that the semantic community can opt to change or discard the rule. “A business rule is a constraint that specifies a policy, business practice, rule, relevant governmental regulation, or physical fact concerning the customer organization’s current business enterprise."
