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?
