I.e., customers usually don't give you a step-by-step, "well, first I check if the customer has an outstanding balance before I ship them anything." They say, "Don't ship stuff to people with an outstanding balance."

In my experience, customers often give you a vague, incomplete and even contradictory set of rules. It takes a lot of careful thought to refine them into something complete and coherent, and it requires considering all the rules together to see how they interact with each other.

The GF approach encourages scattering the rules over different parts of the program, and I can't see how that helps with this process.
