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?
