Creating a business rule
Before you create business rules, formulate your rules by asking yourself the following questions:
♦What business problems do I want to address?
♦Are there any procedures that my system must respect?
♦Do any specifications dictate the scope of my project?
♦Do any constraints limit my options?
♦How do I describe each of these procedures, specifications, and constraints?
♦How do I classify these descriptions: as definitions, facts, formulas, or validation rules?
