Business rule
A business rule describes a business condition or decision that governs how an operation is handled.
Make business decisions explicit
A business rule states the conditions under which a particular handling of a case is intended. It can concern permissions, states or relationships. In a fictional example, a note must not automatically mark a cancelled service job as completed again; adding a note requires the defined clarification.
Formulate the rule with business owners so that it is understandable and checkable. Describe exceptions and what happens when information is missing. Whether implementation uses code, configuration or a manual decision is a further question. Automation does not make an unresolved business rule clear or correct by itself.
