Which of the following best describes a business rule?

A business rule is best described as a guideline for decision-making within a business process. This definition highlights the fundamental role that business rules play in defining the operations and constraints under which a business functions. Business rules serve as principles or criteria to guide employees in their decision-making and ensure consistency across the organization. They help in automating processes and ensuring that decisions align with the overall objectives and policies of the company.

While coded instructions for system processing are essential for software functionality, they don't encompass the broader notion of guidelines that can be interpreted and applied by business users. Similarly, a requirement for user interface design focuses specifically on the aspects of user interactions and does not relate to the decision-making processes or operational standards that business rules represent. Lastly, restrictions applied only to data storage pertain to data management and governance, which is a narrower focus than the broader decision-making and operational guidance provided by business rules.
