Business rules are specific guidelines or principles that dictate how a business operates. They help ensure consistency in decision-making and processes, guiding employees on how to handle various situations. For example, a business rule might state that all customer complaints must be addressed within 24 hours to maintain customer satisfaction. These rules can cover a wide range of topics, including sales, customer service, and compliance with regulations. By establishing clear business rules, organizations can improve efficiency, reduce errors, and create a more structured environment for both employees and customers.
