What is a directive that is specific, practicable, and testable, guiding behavior and decision-making?

A business rule serves as a directive that is specific, practicable, and testable, effectively guiding behavior and decision-making within an organization. Business rules are essential for ensuring consistency in the decision-making process and compliance with regulatory and organizational standards. They provide clear instructions on how to respond to various conditions within a business context, making them actionable and measurable.

For instance, a business rule might dictate how customer discounts are applied based on the volume of purchases or specific promotions, explicitly defining the criteria to be met. This allows employees to make informed decisions in real-time, ensuring their actions align with established policies and objectives.

In contrast, business requirements describe the needs of the business without the specificity needed for decision-making, a decision requirements diagram is a visual representation of the decisions needed without prescribing actions, and closed questions do not provide guidance for behavior but are simply a querying technique.
