What is a business rule?

Answer 1

A business rule typically defines an action based on a corresponding and completed action. For instance, when an account becomes delinquent in an accounting system a business rule can send an email to the account owner requesting payment. Think of business rules as requiring two key parts: 1. What criteria must be met to qualify for a specific business rule (an account has become delinquent based on the last payment received date in the account system) 2. What action must be taken when the business rule criteria is met (when an account becomes delinquent send an email to the account owner requesting the amount owed) Typically, business rules are very specific in nature and can use a waterfall approach to specify the order in which a series of business rules are executed. When X happens, execute business rule Y, then business rule Z. For a more explicit description of business rules visit: http://kellyrshort.com/lpbusinessprocessmgmt.html A common definition of a business rule is: "Business rule is a statement that defines or constrains some aspect of the business. It is intended to assert business structure or to control or influence the behavior of the business. Individual business rules that describe the same facet of an enterprise are usually arranged into business rulesets. Business rules describe the operations, definitions and constraints that apply to an organization in achieving its goals." (Wikipedia.org)
