Business rules are a set of instructions that determine how a process is performed, guiding decision-making by establishing rules that everyone must follow when carrying out certain activities. They describe the operations, definitions, and constraints that apply to an organization, and can apply to people, processes, corporate behavior, and computing systems in an organization. Business rules are intended to assert business structure or to control or influence the behavior of the business, and are put in place to help the organization achieve its goals.

Business rules can be used for a variety of use cases, which can be based on either internal or external constraints. Some of these include approvals, customer orders, shipping, and discounts. By implementing business rules across an organization, a business can save time and money by streamlining work to the right stakeholders and reducing churn.

Business rules can be simple or complex, and can be implemented using checklists or a business rules engine, which transforms one or more business rules into business logic that functions in a runtime production environment. The easiest way to get started with business rules is to create checklists, but a better way to implement them is to use a business rules engine, usually as part of a software platform.
