Business Rules vs. Choices Made in Designing Systems … Not the Same Thing!

A colleague and I were recently discussing business rules. In the course of conversation he used this example: A customer may have only one address. Hold on! That’s not a business rule. Rather, it’s a design decision (probably a poor one) some IT person made in creating a system model. The business wouldn’t (and couldn’t!) make a real-world business rule about customers having only one address. But a design decision might be made to record only one (in a system). Eventually we agreed the desired business rule probably was: A customer may have only one preferred address.  ~~~~~~~~~~~~~~~~~~~~~~~~~~  This post excerpted from Building Business Solutions: Business Analysis with Business Rules (2011).

    I see this more and more. One of the reasons, I believe, is because BAs only document business rules during design as they still seem to believe that business rules are about the system and not about the business.
